I am deeply shocked. Thank you for this crucial information - that alcohol may not be healthy. I may need a drink to help process this information...
A shot of heroin would be far less carcinogenic.
Same :/
I think I need a smoke..
Cheers🍻
Way ahead of you bro
As someone who accidentally ate a moldy cherry tomato yesterday, my body very quickly notified me of the potential health risk
my sides
That's terrible. Top of tier list with it
I accidentally ate about 20 mg of 2-methoxy-4-nitroaniline (a known mutagen) last year. Is this bad?
@@kobold7763 he should ask us all to submit dangerous mistakes we've made and rank them on tier list.
@@kobold7763 the best/worst part about your comment is i cant even tell if this is real or not 💀
The idea of a “Carcinogen Tier List” is just so ridiculously funny to me.
Why?
@@MrRUSINAIt's unexpected considering how to a normal person, ranking carcinogens could make you look like a psycho.
@@Newguyatworkim a psyco and I want to know all of the carcinogens out there😂
if keeping tabs on how deadly substances are makes you a psycho then its better than being a dead idiot. even within dumbass capitalism you can sue over your now shortened lifespan
So funny you could 💀
Radiation therapist here. The most common exogenous factors we see strongly contributing to cancer development are: heavy smoking, heavy alcohol consumption, HPV, and high sun and exposure.
Here’s common examples:
I smoked a pack a day for 25 years.
I drink 5-6 drinks a week.
I do both of the above. (This one is far and away the biggest cause of preventable fatal cancer)
I got HPV in my throat, and never knew until I got cancer.
I tan or get prolonged sun exposure a couple times a week.
Avoid these risks and you’ll skip everything you could possibly prevent on your own. The rest is luck.
Just don’t eat cadmium or whatever. Also, quit vaping. We don’t know what it does to the human body, yet.
I think vaping is probably worse for you than cigarettes tbh
Bu…b..but what about my artificial fruit rings that taste worse than fruit?!
5-6 drinks a week? 😂 I'm getting cancer
Dude I know it's apples to oranges but a pack a day gotta correlate to like 3 drinks/day
Reminder that this is usually the case for white people. People of color have better protection to sun rays. In fact, the recommended sun exposure may vary depending on your skin. For white people, it's around 15-45 minutes minimum in order to generate vitamin D (and higher doses of sun rays may prevent eyesight issues; there's evidence that show that children who spend 1-2 hours outside are less likely to develop eyesight problems), whereas black people may require a few more minutes of exposure to the sun.
Also, another issue is vegetation and trees. If you're able to protect yourself from the sun with trees, you're able to be out for a longer period of time. This is an issue in car centric cities as there may not be green areas nearby, and sun exposure may be more harmful to all forms of life.
I have to say, out of all the warning labels for safety, carcinogen has to be the most eerily creepy/terrifying
It’s so well designed
Creeping death
I feel like safety warning labels might be a good future tierlist???
@@toastothetoaster7949 GHS tier list would be fun for sure.
Im quite unhappy with this symbol, it also labels comparatively benign things, it's not for carcinogenes specifically, but for all kinds of lasting damages, from dry skin to allergies to heart failure to cancer.
A specific symbol for carcinogens would have been greatly appreciated.
I feel it's a step back from labeling carcinogens with a skull in the old system together with acutely very toxic compounds.
Fun fact: most carcinogens have multiple aromatic rings because they intercalate between DNA base pairs through Pi stacking. This often leads to gene silencing by blocking translation
Fun fact for people with PhDs maybe
So basically it stops the gene from geneing, truly a carcinogen of all time
@@danthompson5797 this requires a basic biology class, and 1 (maybe 2) semesters of basic organic chemistry in college
@@zachingram04 thank you for leaving this comment, I'm going into college and interested in what classes I should take and this helped me think
@@angelopauli1961 best of luck! its a lot of fun
For the mold one, I am disappointed you didn’t mention how prevalent black mold is in buildings across the world. Obviously no one will purposely eat a ton of moldy food. But I myself have experienced living in an apartment infested with black mold and within 2 months I became extremely sick, constantly had respiratory issue, extreme brain fog especially when entering my bedroom (where the mold was most concentrated), mood disturbances and even developed asthma. I would cough up phlegm that would literally, no exaggeration, have spores inside it. When I saw that in the bathroom sink I couldn’t stop crying. When I saw how much black mold was in my AC unit alone I was terrified. Everyone I show the pictures to I have to give a warning because it’s that disturbing. And that common.
I know so many other people who have experienced the same-this being NYC, which is supposably the best city in the world. There is very little tenant protection for this despite mold being a huge tenant’s rights violation in NYC. I am so lucky I was able to move out of my lease. Many people don’t have that option and have to live for years in toxic environments. There’s even a phenomenon called “Sick building syndrome” where people who feel extremely ill inside their apartment buildings feel better once they go outside. This is due to toxins such as black mold and water damage as well as a lack of airflow or light in many “modern” apartments, which in all seriousness rival tenement housing in terms of toxicity. Mold is a huge human rights issue that remains ignored in favor of landowner profit.
Damn. Well now if literally The Last of Us starts happening, we know who to blame 💀
❤
This is the case in my building in Vancouver as well. It is milder in my home but I am constantly sniffling and coughing phlegm because of it. I can't wait to move so my pets aren't affected any longer
Mannnn I live in nyc, if y’all don’t start getting that bleach vinegar water (majority should be water to prevent making dangerous gas) combo with a scrubber with a mask and start scrubbing☠️the type of mold I had was brown n had no long term effects (I think) but every time I spot one, I get to scrubbing!
Mold is underrated as a problem that people always underestimate.
Thank you for this comment.
22:50 completely agree. It always pissed me off that cleaning chemicals, and other products that can be bought at hardware stores, grocery stores, and so on, never list the chemicals included. If food products are required to list ingredients, then so should other products. I always try to find an ingredient list for chemicals I buy that I’m not familiar with, but it should 100% be listed on the package
Most of them have an MSDS sheet you can look up if you’re truly determined to find out. Most people wouldn’t care enough to read a label, let alone look up the MSDS, but to me it seems like “survival of the fittest.” Let Darwin do his job!
@@Sniperboy5551 Alot of things have blank or near blank datasheets, if they dont have to list an ingredient because its not recognized as having a danger, they wont.
@@JohnSmith-fq3rg true but plenty of cleaning supplies got em. Plus can't have the Gen public knowing anything at all
@@eank3429 It's not so much a concern about the general public knowing, as much as the competition. If you show the exact chemical end product of your "secret recipe," reverse engineering your profitable and efficient process becomes trivial for industrial r&d chemists.
@@Sniperboy5551 true. I try to use the MSDS sheet to find alternatives to expensive or namebrand products when online searches fail me. (some examples are removing burned tar/wax buildup on moulder bits, dealing with surface rust on different materials, non Teflon/silicon dry lubricants that won't fisheye stain or paint finishes)
This video has been know to cause cancer in the state of California
“…and birth defects or other reproductive harm”
California is cancer.
Also, if you’re of asian descent and/or cannot process alcohol normally (like red flushing other side effects), acetaldehyde stays in your system far too long and in essence, drink for drink (vs normal process) increases your exposure to cancer :/
Important UPDATE: While the ALDH2 enzyme primarily targets acetaldehyde, it is also involved in detoxifying other aldehydes, including 4-HNE (associated with cancer, etc). So, individuals with the ALDH2 mutation may have a reduced capacity to metabolize and eliminate 4-HNE effectively. 4-HNE essentially comes from the oxidation of Polyunsaturated Fatty Acids (PUFA) and is derived from Omega-6's. So we suck at alcohol, but we also suck at foods high in PUFA's. Lol.
My partner is filipinx and I have to keep nagging them to avoid alcohol because they're in denial about having the Asian flush because it's not super visible with their darker skin tone. But I can definitely see their face change in color and look a little puffy when they drink
@@Alex-fc8xn I took took way too long to realize I shouldn't be drinking alch, but it definitely is damaging. Giving up alch is hard when everyone around is drinking, so I would say, there are other stuff out there when consumedd in very careful moderation should be relatively safe.
@@L3uX Like cannabis products, depending on method of consumption and how your body reacts to it. Considering it's literally prescribed as medical treatment, and shown to have benefits, it's a good alternative. Smoking/vaping it isn't good for the lungs, but edibles and sublingual oils/tinctures are pretty safe and can help with social lubrication without causing the same sort of disinhibition or risking overdose unless you are truly consuming ridiculous quantities
note!: This does not apply to everyone of Asian descent. My dad is Korean and he can drink alcohol like it's water, I have literally never seen him blush.
@@Alex-fc8xnplease dont use filipinx. filipino is already gender neutral.
as a filipino, (im very sensitive to alcohol overall too) its a pretty similar case for me
As someone who works in a lab, I'm always super surprised (and terrified) how many people handle carcinogenic chemicals without the proper ppe. I've also made it a point to avoid any and all shampoos or body products with include any sort of variation of formaldehyde becuause that is also just crazy to me that that's even allowed. This was such an interesting and fun video to watch!
That is allowed?
Can you list some variations?
@@xXDESTINYMBXx Do you mean about formaldehyd being in cosmetics? I'm aware that Diazolidinyl Urea, Quaternium-15 and DMDM Hydantoin are products that are based off formaldehyd and are often used in Shampoos (like Maui Moisture, Axe, OGX, but also many others). Some of these ingredients are banned in the EU (like Quaternium-15).
I worked at NIH in 1966. The labs were full of radioactive material in giant glass bottles. Since practically all the scientists were heavy smokers, the radioactive stuff was small potatoes.
You clearly missed the whole "it's the dose that makes the poison" and benefits vs risk explanation at the beginning. As for formaldehyde, I'd rather have those negligible effects than die of mould poisoning. Like the dose is so little it's safe for even babies. I mean would you never drink coffee or sit by a campfire again as well? Sounds ridiculous cause it is. Heck the friggin sun is a cracinogen and people don't just cancel the sun lmao
You can avoid carcinogens for your entire life and there is still a very real chance that some cell somewhere decides that it is having a bad day and decides to make that your problem. no amount of caution will ever reduce your odds of cancer to 0 (obviously there is merit in reducing your risk). In my mind it's far more productive to improve your odds of surviving it if it happens, and chances are most of those are things you should probably be doing anyway.
And if you do manage to dodge both cancer and heart disease, congratulations! You win the grand prize of getting to die from Alzheimer's.
All it took for me to develop skin cancer was getting sunburnt too many times but I got lucky and had surgery to remove the skin cancer from my chest (upper left corner) and I still have regular skin checks every six to twelve months as a precaution or more regularly than every six to twelve months if I find any lumps or legions that I am concerned about but so far no sign of any skin cancer. It wasn't major surgery having the skin cancer removed from my chest just done under a local anesthetic at my GP's (doctor) clinic and I only needed three stitches
@@craigpater6278 may I ask you what latitude you live?
@@r.guerreiro140 I'm not sure about what latitude as I'm not familiar with latitude but I can tell you that I live in Adelaide, South Australia (South Australia is a state in Australia and Adelaide is a city in South Australia)

Up to now I can name 5 people who had skin cancer
I do my best trying to follow a sunsafe attitude
hey i remember one of my organic chem professor told us about a time when someone stored benzene incorrectly and, because of the fumes, the cancer cases at her university skyrocketed
I have a couple of interesting anecdotes for ya:
1. I have Crohn’s disease, and most/all treatments for the disease require using immunosuppressant drugs. The first one I took was called Azathioprine, and increased risk of skin and bone marrow cancers
2. Lemme tell ya, you’ll be happy to wash your hands with a solvent if you’ve ever spent any amount of time handling roofing tar barehanded. I remember probably scrubbing hard with dish soap 5-6 times before one of my old bosses came by and said “hey, try some kerosene.” The tar came right off with one simple rinse and wipe.
Obviously, don’t try this at home.
I can recommend vegetable oil for that kind of contamination. Dilutes/mixes with greasy stuff, doesn't penetrate the skin so quickly, and is then easily washed off with soap.
Work wonders also for paint - even if dried (but not yet hardened).
UC and liver transplant recipient here. I'm pretty much just waiting for the shit show down the line......
Dish soap itself is toxic too lol
Can't help but wonder if point 2 is why point 1 is a thing.
@@RichXVIII almost definitely not. I was diagnosed with Crohn’s at the age of 8, and the “washing hands with kerosene” event happened maybe once or twice, around the age of 23. Definitely no correlation.
Hypochondria makes it basically impossible to ignore that feeling that everything is out to kill me. However I do like things like this, because it at least helps me to understand what not to concern myself about so much. Thanks for the extremely informative video!
That NNN joke almost had me choke on the smoke from my joint too. Yes, I know, it's horribly carcinogenic. Irony is my friend.
I used to work for a shoddy company in the UK that made printer inks. We were instructed to clean ourselves with MEK ( Methyl-ethyl-ketone ) . i trusted my supervisors as a young man. I know now that it is toxic, causing neurological illnesses. No long term studies exist for it's carcinogenic effects. I felt nausea often after finishing our shift. Thank you Lyson Fluids ! I'll be seeing you in court soon if you are reading this.
MEK is extremely flammable, and vapors in certain concentrations are explosive. If you were wearing synthetic clothing you could have discharged static electricity and caught fire, or worse.
Go get em!
Good luck! That sounds terrible 🤢

I used to work as a health and safety officer at a university. I once did a breakdown of what's wrong with wd 40 sds to teach researchers what to look for and how to find missing information. A video on how dangerous is the chemical in your home would be great. WD40 btw is pretty dangerous. That sds is downright criminal in my opinion.
I'm a health and safety officer as well and I'm always laughing when I look at wd40 sds
It's insane how they are getting away with it
where is league of legends
Due to its deadly affect, it was banned so be talked about in his country (jok)
I work in pharmaceutics and the impact of pure suspicion of being carcinogenic can be the death sentence for any otherwise harmless and usefull drug

You conspiracy theorists need to stop attacking health care.
I’m surprised you didn’t put benzene higher since we treated this as one of the worst things you could get exposed to in the lab. We pretty much treated it as liquid leukemia.
Lab exposure to pure benzene ≠ the exposure risks normal people face from trace amounts in gasoline.
tbh most of the public outcry over benzene when its carcinogenicity was discovered was just how frequent occupational exposure was for so many workers who used it daily such as dry cleaning workers. occupational risks dwarf the risks of single exposures by many orders of magnitude.

@@dieSpinnt I think you replied to the wrong comment
Surprised you didn't include ethidium bromide since every student running a DNA gel has been told this stuff is concentrated cancer.
One of the professors I worked with said that if I dumped my hand into a bucket of ethidium bromide, it would be equivalent in terms of cancer to smoking a pack of cigarettes. So not great, but not a complete disaster. No idea exactly how true this is, but interesting nonetheless.
I can’t believe vinyl chloride wasn’t classified as a hazardous chemical and was allowed to be in the crash that Norfolk southern’s neglect and mismanagement caused. I wish the best and hope help can come to the people who will suffer because of it.
I had an uncle who was a career Marine. He spent a lot of time at Camp LeJeune. Once I saw all the ads for legal defense regarding the polluted water at LeJeune. I googled his name, and discovered an obituary. He had lived in an assisted-living facility before his death, and cause of death was "complications of Alzheimer's." The last time I saw him was at my wedding, 49 years ago. But he had five kids.

One of my coworkers used to wash his hands with naptha at the metal shop I worked at. We worked with soldering lead daily, there was a custom order that thought required a "soak" in "cleaning vinegar. So what they actually used was GLACIAL ACETIC ACID, and they used this to wash parts every time despite me trying to convince them it was stupid (I don't wanna get into the nuances of lead chemistry, but just know we already used hydrocloric and it worked better). These guys didn't know chemistry, anyways on that custom order we left a mixture of acetic acid and some other things and lead pipes soaking over the weekend. I told them not to, but we ended up growing lead acetate crystals. That place fucking sucked lol
Wow!
We'd use shit tons of that naphtha in commercial roofing. We use it to clean surfaces and since we'd spread it so often on such large areas we had fun breathing it, it evaporated quick like minutes. And we had giant tar melting furnace. I worked with a guy who exclusively loaded, mixed and dropped hot tar from this furnace. It doesn't smoke so much in small bucket amounts and in transport but near the furnace it's terrible. This guy would stand there with a stick stirring it with a cig in his mouth and would cough and spit into the hot tar. His face was yellow like Bart Simpson yellow. I think that dude is gonna die he's the only one who'll do it get paid allot for it.

Came back to this video after hearing about the vinyl chloride spill in Ohio. I thought it sounded familiar and you had covered it here! Scary stuff, I wonder what the remediation process is supposed to look like and how well they're actually following it through.
Do you know anyone affected by the incident? What is the main concern/anxiety you have surrounding the incident?
@@That_Chemist I'm worried they may be sending people (who have no other options) back to their homes too soon. Even if the general air, water, and soil measurements are as safe as they say, they should be doing a much better job communicating these results and reassuring residents. The EPA's power as a regulatory body, especially in recent years, is worthy of scrutiny and I understand people's mistrust. I do think there's a lot of misinformation out there, though, especially on the remediation process.
The real question is how much exposure is necessary for a significant effect size.

My grandfather that died at 44 of multiple organ failure but the lung cancer killed him first... He grew up in auto body shops in the 50s -90s always washed they're arms and hand with xylene or lacquer thinner. Supposedly both enter the bloodstream within milliseconds of exposure to the skin. They think that partly why he had so many issues. Plus they painted and sanded without masks.
In 2000 I was a 21 year old apprentice in an auto body shop. As the young apprentice I got the crappy jobs of cleaning stuff like paint guns. We use a strong industrial paint thinner for this that was "Not To Be Sold to Consumers". The rubber gloves we had in the shop were useless against thinners and just bulged up and broke within 60 seconds of exposure so all cleaning took place with bare hands. I spent hours with my hands soaked in these paint thinners that were a mix of acetone, toluene, benzine, methyl ethyl ketone, xylene and dozens of other highly volatile organic compounds. After 6 months of doing that the skin on my hands was thick, dried out and cracked. I started having nervous system issues, shaking hands, inability to sit still, high anxiety, loss of concentration. I didn't even realize this was what was happening until about a year or two after I left the job when all the symptoms went away after I was no longer being exposed to these chemicals. That was 24 years ago and I still don't have liver or kidney cancer but the chronic exposure only lasted for about 12 months. Working in the auto body shop some of the guys used to joke that you don't see old body men, they don't live into old age. Today, all the paints are water based and can be cleaned up with low VOC polar molecules, AKA H2O.
Im glad to hear you made a recovery! I hope we can help stop people who might otherwise be exposed
I have to stop fucking with automotive paints and solvents. It is such a hobby of mine but after covid and long term exposure to this stuff you just really opened my eyes to problems I've been having and chalked up to "stress" or "after effects of long covid." :/
@@KenzertYT Yeah dude, it's no joke. These things can ruin or end your life. Take precautions. Take care of your body, you don't often get second changes with organ damage.
We use acetone heavily in our composite shop to clean tools and tables after wetting out cloth with epoxy. We always wear gloves. I can't imagine using a mix of all those solvents with bare hands. Admittedly I've gotten acetone on my hands before once or twice and it really dries them out.
I had a landlord that liked to spray paint in the basement where me and another person lived
The basement would smell like spray paint and we inhaled this shit constantly
My grandfather developed stomach cancer a couple of years after retirement. He had been an engineer all his working life using milling machines and lathes so he had long exposure to cutting oil mist, now considered to be carcinogenic.
A lot of older cutting oils contained chlorinated components as extreme pressure additives. Machining makes a lot of heat, no doubt decomposing those compounds to all kinds of nasty stuff...

Formaldehyde story, a colleague told me that when he started his research career in the marine biology, they would go on the sea and catch fish and other animals and put them in buckets of formaldehyde. When they came on land the animals were transferred to new containers and when they went to the sea the next time, they would pour the buckets of used formaldehyde into the sea... We're talking here about like 30 years ago in a Western country... Crazy...

Okay, so,
1. Go into the field to apply old fashioned pesticides to your obscure mushroom and wild ginger garden, and wash your hands off with some some beneze.
2. Wait for the food to mold while you apply antique makeup generously to the face and smoke vape pens.
3. Collect the moldy food and preserve it with numerous additives, until you are ready to eat it, at which point, burn it until completely blackened.
4. Tend to your garden near a coal-burning power plant for warmth in the winters. This will place you near the railroad lines you must lick on a daily basis with your tongue in order to meet dietary iron requirements. If the taste is too strong, preceed with a few good puffs from a cigar.
5. Experiment with numerous industrial chemicals you find in that abandoned warehouse over there, because you have watched X-Men, and figure your odds are looking pretty good. Plus, you remember that one of them (you don't remember which) is supposed to treat lice, and you recall that you have those too now as punishment for crimes against life and reason.
As long as you aren't working with vinyl chloride you shouldn't be exposed to it...

Having worked with 2-Naphtylamine: You have to synthesize it yourself cause no one sells it. It's an autoclave synthesize and you get greeted with a red paste, it is impossible to filter creeps up the walls of everything you want it to recrystallize from (steel, glass, filterpaper and plastic) crystallizing on the edges and falling eventually of them in the fumehood. The crystals are so fine, they immediately spread over your entire fumehood, breaking apart into much finer dust that manages to simultaneously stick to everything yet also aerosolising really quickly, this and the articles i read about it, conveniently causing bladder cancer in like every subject it comes across makes me never want to work with it again :3

Hey That Chemist, some of us laymen who work in construction and or machining deal with toxic inhalants. Would you ever do a tier list of such chemicals as may be common in such industries, e.i silica, solvents, aerosols, asbestos, MDF and/or wood dust, metal coatings, compounds with lead, etc
I second this
Omg this would be great
Especially silica - it's become the new asbestos in Aus.

I am a motorcycle mechanic, and it just didn't occur to me that being in contact with gasoline was a cancer hazard. I always went out of my way to wash my hands after being in contact with gas, oil, engine grime, etc. I guess I'll start using gloves way more often now. Thankfully, I only do it as a hobby, or a side hustle. But still. Better safe than sorry.
Greatly appreciated the bloopers at the end of the video! Excellent tier list, as always. As a non-chemist, i appreciate knowing what I should avoid and what is safer than I thought.
My home town has massive agricultural fields called bogs for a mono-crop berry. Helicopters would drop pesticides and herbicides and we'd be informed to stay inside as it catches in the wind and fields are right next to, in front of, or behind most houses. They used round-up heavily for many years, not sure if they still do. But as a small town everyone also uses wells for drinking water. Additionally the cranberries are harvested every fall by flooding the bogs via pump houses that pull from the numerous ponds around town (berries float). After winter the water is emptied from bogs and pumped back into the ponds. In high school pretty much the entirely English department got cancer and librarian died of cancer too. I have friends from high school who got cancer and one had testicle removed shortly after graduation. My dad just finished 6 months of chemo for a blood cancer. Round up is no joke, especially chronic exposure to it..

Couldn't agree more on the listing of ingredients, especially in consumer markets. I realized how little information there was when I was trying to find information on what I could use to clean and lubricate tools properly and there's really nothing.
It used to be fairly common for people to buy used railroad ties to use for projects, since the pentachlorophenol basically makes the wood last forever without breaking down. My grandparents bought some a few decades ago and used it to build a tiered garden in their backyard. I grew up eating home-grown veggies from that garden, and when I found out that railroad ties have toxic chemicals in them, I of course freaked out and started Googling. Thankfully, from what I've read pentachlorophenol doesn't really leach into the ground after the ties are laid, and even if it does it isn't absorbed by plant roots. So the danger of exposure to humans comes mostly from the manufacturing process.
Dude I'd have been super worried too. Did you know people used to use an oil and solvent mixture to preserve fence posts and other in-ground posts? It totally works but it freaks me out.
You should do a tier list, based on absolutely nothing other than your own opinion, on what the overall best chemicals are. Not sure why but it’d be cool
Pretty sure he already did that.
Given how popular Betel chewing is in southeast Asia, arecoline is actually a risk to a significant population.
Worse yet, it's commonly chewed with tobacco... Which is also known to cause cancer.
Thank you for the time you put into this, I had tried to do something similar a few years back for my personal use and was overwhelmed by the time to do the research. Here you have done it for us and this certainly is a keeper as it may help so many people if they will head the advice. Godspeed for the valuable information ❤.
15:25 I heard from a friend that he told someone how well brake cleaner and chemtool works at cleaning things. The guy he told worked as a manager in some sort of factory locally and he ended up having the employees use chemtool to wash up when they got grease/grime on them. My friend said he talked to the guy a few months later and the guy said that they had to stop using it to wash their hands because of how many employees started urinating blood. He was shocked when he realized that the guy thought "cleaning things" included "cleaning your hands"
Take that with a grain of salt because it's second hand info from a guy who is self aware of being "dim witted" and "not very bright"
I knew an old mechanic guy who liked using volatiles to clean his machined parts. One time after doing a port/polish on a little lawnmower engine he just doused the thing with gasoline and started rubbing it down like we weren't in a little garage. Fumed out the whole shop until we got everything opened up. My dad worked on the California offshore rigs I'm sure he has some wild stories.
The SDS for gasoline is actually pretty scary, especially for something we interact with regularly.
There are volatiles that give you cancer and there are volatiles that set you on fire and incidentally can give you cancer. Choose the former not the latter.
When I used to build aircraft, we would soak bearings in gasoline to clean them (we basically put them in a tub outside the hanger where no one was working, and used gloves to handle them after, but still)
There's a safer alternative in the form of shellite (aka 'white gas'), it has similar volatility to gasoline/petrol but minimal aromatics content. Not a good substance to put in engines however, the octane rating is around 60 so most engines will 'knock' if you use it as fuel.
In some parts of Australia service stations only sell 'opal' fuel which is similarly a low aromatics petrol, albeit with an octane rating equal to normal fuel. This was introduced to combat the petrol sniffing epidemic, the aromatics in regular fuel are responsible for most of the intoxicating effect so sniffing Opal won't get you high.
@@nerd1000ify fascinating and good to know.
In my case it was less a "this is the exact thing we need for this job" and more a "we had it to hand and it works." Was also not a job and was about 15 or so years ago.
Really enjoyable, though, small aircraft are really interesting. Lots of cool simple, yet ingenious, engineering on them.
And skin dope was probably more dangerous than the gasoline.
As a little kid I was at some time forbidden to play in the garden behind our house. The reason was that some of the flower beds had edgings made of - wait for it - old wooden railway sleepers that someone had gotten hold of somehow. This was in the early 80s. No idea how old those ties were but it looked nice. And when it rained there were beautiful shimmering puddles of water all over our garden. Looked nice but smelled awful as far as I remember. It turned out the wood was treated with a cocktail that included Pentachlorophenol and Lindane. The garden was off limits for the entire summer and heavy machinery was brought in to take off much of the top soil.
Interesting to know, given that a lot of my garden uses old railway sleepers as retaining walls and we had a big old stack that we used to play on as kids 😮
Vinyl Chloride became very popular this year

30 years ago, before the internet, I wanted to try out an old synthesis I found in the library. Went to the chemistry shop, asked for a bottle of benzene, not knowing sales of the stuff had been restricted decades ago. They did sell toluene, which was fine, since the benzene was only needed as solvent, not a reagent.
Ten years later, when I did my military service in the military pharmacy in Evere (Belgium), I came across bottles of pure formaldehyde. The doctors prescribed it as treatment for sweaty feet: dilute with water, and soak your feet for 15 minutes every day.
you can still buy it, you can buy almost anything, they just hike the prices up

For years, I was the sole Chemical inspector for Ortho-toluidine coming into the Houston ship channel. I remember a few times the whole plant was being evacuated into inside safe zones because I was just getting samples from the ship. One time while the ship was in port, myself and the ship “pumpy” were pulling the samples and my SCBA ran out of air midway in sampling. But I’ve worked hundreds of chemicals in my career so it was nothing extraordinary. We transported them in rubber coated bottles for in case they broke. And it’s MSDS numbers were all 4 to the max. The best thing that ever happened to me was leaving that career field.
The formaldehyde comment made me laugh, because nothing about funeral directing/embalming was mentioned! Loved the video :)
I really like this tierlist, but I would have formaldehyde at least in A tier. I worked as a chemist in the polyurethane and polycarbonate production and know that this stuff is everywhere. And if you’re not an Amish person it’s just really hard to avoid it in modern times
Yeah a LOT of stuff produces it when breaking down, I remember reading that it's also frequently used in clothing production to prevent molding while the clothes are stored before sale
I worked at the pathology department of a large hospital for a short time. Almost all tissue samples were treated with and stored in formaldehyde before dissection. This is why I know that baby brains turn curry yellow after a few days in formaldehyde.
Vegetable oils contain aldehydes and McDonald's frying oil contains a preservative that breaks down into formaldehyde. Stay away from fried foods unless it's peanut oil, olive oil or coconut oil but coconut oil is higher in fat.

I was exposed to formaldehyde through floral foam. We had gloves, but no masks. I had to leave the room because my lungs felt like they were burning. I suppose I might just be more sensitive than others because only two other people had to leave, but we should at least have been given masks.
Please do a video on addiction. It strays a bit from chemistry into human behavior but I think it'd be really interesting to learn about the pharmacology of known addictive compounds.

I actually work in Formaldehyde testing for particleboard. I regularly use Bis(chloromethyl) Ether at least twice a week in order to test formaldehyde levels using a spectrophotometer. Most products released to market are well below the limit required (which sits around 0.1600 ppm/m³) and even before they are released all particleboard (that we make at least) is quarentined for several days to allow as much Formaldehyde to escape as possible. Fortunately most products by the time they get to a consumer will be below 0.0900 ppm/m³.
You make a good point about thinking critically and considering factors like exposure time. Sunlight is a carcinogen because of UV rays, but no doctor is going to advice against going outside, or going for a walk in the park.

I've worked with ethylene oxide at production scale on an occasion. Our attitude towards it was a breach of containment, and accidental exposure would guarantee cancer. Who knows when? We joke that way about a lot of the reagents we worked with; however, we were serious about using supplied air when feeding, sampling, purifying, and so on.
34:37 - "Death occurred as soon as 14 days after treatment and continued throughout the 35-day observation period."

32:29 I absolutely believe your hypothesis. I used to have a few cigarettes per year, and nicotine salt vapes definitely feel much more like a cigarette than freebase nicotine vapes.
This may also be because the natural form of nicotine in tobacco is the salt. It's nicotine tartrate. Freebase nic is much harsher to the throat than salt nic is. The older box mods vaporize a lot more liquid so the freebase nicotine could be used at lower concentrations and it wasn't too acrid. The newer small vapes work at much lower wattages so to deliver the same amount of nicotine per draw, the concentration had to be greatly increased. Freebase nicotine would be too harsh at those concentrations so they switched to salt nic.
@@SafetyLucasTobacco also has other phytochemicals with mild MAOI activity and other stimulating mechanisms.
I'm glad I was able to quit nicotine, I liked it way too much
When I was a flooring contractor a few years ago I'd hear stories of some of the old timers that would wash their hands daily with acetone and their hands and forearms would end up pitted as the acetone would leach through their skin and disolve the fats beneath their skin.

Acetone is a very good solvent for many lipophilic compounds, like mitragynine and Delta-9-THC.

regarding 24:03 i believe a study has recently came out stating that sucralose is in fact carcinogenic but the concentrations that cause cancer are around 8,000 times greater than can be found in a can of fizzy drinks.
Yes there's a metabolite of sucralose that is inherently carcinogenic when applied directly to a cell on a petri dish and you would need to drink hundreds if not thousands of cans to equal the serum concentration of the metabolite.

@@That_Chemist I heard about a stomach/digestive tract yeast, that sounds more logical.

Like 90% of my snacks have prop 65 warnings on them (acrylamide I think).
I find this very interesting! One day could you talk about it? It seems like a sizable amount of the Korean and Japanese processed foods at the mart have cancer warnings!?
Almost every CA product seems to have those warnings (I'm European, don't live there, luckily). Either literally everything is toxic, or they needlessly slap that on everything. Ironically, it probably causes a "boy who cried wolf" effect with people ignoring it altogether.
It’s on a lot of imported foods. I’m part Chinese and live in California so I get you lol. I’ve heard that it’s there just to keep lawyers happy and that there’s little actual danger, but I still eat those things in moderation just in case.
I would absolutely not worry about that label. Humans have eaten burned food for a long time, there is a huge selection pressure for humans to tolerate that stuff better then lab animals. Some of the most carcinogenic compounds in the world seem to have no effect on humans, as far as epidemiological studies could find.
I would, however, worry about heating up meat that was preserved with nitrite salts.
@@stefangadshijew1682 I’d strongly suggest looking into acrylamide and similar advanced glycation end-products, the prop 65 label is often a bit overblown but potato chips specifically are by far and large the single most potent dietary source of acrylamide.
@@TheBoxOfRocksFTW Hey there :) Oh yeah, thanks for the suggestion, it seems I'm not up to date. To explain my previous scepticism: Last time I checked, state of the art was that acrylamid is a probable human carcinogen based on animal studies, but it couldn't be shown to be one for humans. It was however suggested that acrylamid is a reliable indicator for the formation of four specific heterocyclic amines that are among the most potent carcinogens known in certain animals, but again, it couldn't be shown that this is the case for humans - and furthermore, it was demonstrated that the mechanism of carcinogenicity (further metabolism by specific gut bacteria) does not apply to humans at all.
So that seems to be old news, I'm going to read up of the glycidamid.
This is very fascinating and interesting information! 14:09 I want to make one note though, betel nut chewing is actually extremely common in other parts of the world.. It was a major thing in my grandmother's village, all of the older generation would usually be chewing these nuts. Many of them had obvious mouth sores and mouth problems due to this. Luckily my grandmother never developed cancer before her passing, but the inside of her mouth was really messed up. While I know it isn't a big problem in the west, it definitely still is a major problem elsewhere. I'm no expert on the situation as I moved to the west when I was young myself but I still remember how it affected my grandmother.
Agh. As a chemist working in an environmental lab and frequently running a GC/MS that's calibrated (by yours truly) to detect many of these semivolatile carcinogens (and more)...this hurts. I mean, I knew I was fucked, but just hearing this from another chemist really drives it home. Thankfully the fume hoods work when I'm making the calibration mixes and I always replace the GC vial caps of the calibration standards immediately after they're injected, but damn. I'm probably being exposed below occupational exposure limits, but in non-zero amounts. Can't wait to hit my 40s/50s/60s and develop a rare as fuck cancer that's untreatable/late-stage. Good times.

I want this in a video! I remember a long time ago I tried to make ferric chloride with HCL and nails, in summer time outside, I noticed that it was so hot outside that the HCL was fuming this white smoke out of the bottle, I APPARENTLY breathed in WAY TOO MUCH HCL and basically what happened was this damaged the cartilage in my ribs to the point that breathing in made my ribs pop lock a knuckle and EVERY millimeter of breath I took was the most painful thing I've experienced, kinda like if someone beat your ribs with a baseball bat, after about a week later the pain started going down and my lungs/ribs started to heal, but to this day my sternum pops like a knuckle. 0/10 do not recommend breathing in fuming HCL
Things I actually knew about:
* Benzopyrene. The author Francis Spufford wrote a chapter as part of a novel which stepped through the (or one likely) pathway benzopyrene causes cancer. Fantastic writing, also, absolutely terrifying.
* Cyclosporine. Remember it as "that immunosuppressant drug that was isolated from Norwegian dirt".

My uncle was an alcoholic and he got cancer of the liver, pancreas and it spread to his bones. He died so i’ve seen the destructive effects of alcohol in my own life

@@Yourcheerz Yeah there’s many factors that could lead to cancer, environmental factors, or simple bad luck and aging. That’s unfortunate she got it so severely and passed away, typically you wouldn’t expect to get such an aggressive cancer if you aren’t a drinker, but it can happen to any of us.
I used to drink but I decided to stop entirely so I almost never drink anymore and if I do then only in moderation. I’ve seen people ruin their lives from alcohol, and it really is a poison and makes me feel like shit even from a few drinks. It’s disgusting shit and will take years off of your life

cyclosporine was one i definitely knew as i have to handle it sometimes for work. we do special training to handle it and dispose of it and any waste someone consuming it creates
"death was observed 13 days in and continued for rest of the 30 day trial"
I'm happy that by watching this, I assured myself that my graded unit about the toxicity of different aromatic hydrocarbons last year was accurately presented.
I feel even better about the A it got me now :)
Excellent!
watching this channel revived my love for chemistry as a comp sci major, thank you for these videos!
Great to hear :)
I didn't understand 90% of this video, but I think my main takeaways are don't smoke and make sure your shampoo isn't releasing formaldehyde
I am on a pharmacy rotation through an oncology clinic right now, so a chemotherapy video would be very interesting to me. Can't wait for it! Thanks for the nod to cyclosporine and tylenol. Cyclosporine is used as an eyedrop for dry eyes branded as Restasis! I was hoping cyclophosphamide was going to make the cut in the video.
Me too.. im sure its cytotoxic.
I am your #1 fan (and used to wash my hands with toluene to remove tar), but there are a number of misunderstandings in this otherwise great video. I shall not address the intrinsic problems with IARC classification (which someone really, really should), but rather:
1 - the areca nut is not obscure: I can buy it from a local speciality store 50 m from my home, and I live in Denmark. In E and SE Asia, probably around one billion people chew it daily. It's the only thing that really competes with tobacco for mass cancer causation.
2 - AFLatoxin (not aLPHatoxin) is not in every mould, it is in a very specific one, Aspergillus flavus, which grows almost only on nuts and grains. A. flavus is unable to grow under 5 °C, so the many moulds that spoil food in fridges are basically guaranteed to be free from it. It is true that there are other, more obscure carcinogenic mycotoxins in, e.g., some strains of A. niger, but one shouldn't assume something as terrifying as aflatoxin is present in all mouldy food, some of which is eaten intentionally (think soy sauce and blue cheese).
3 - where are the nitrites?
Vinyl Chloride was what was in those tanker that derailed in East palestine Ohio. Something like 6 full rail cars were left just to burn because of fear of an explosion not to mention all of the treated wood rail planks that you also spoke of being treated with a carcinogenic.
In my lab, a women was working on a sulfur mustard "mimic" (like less active, only one chlorine). The purpose of the study was to find good inhibitors to this S-CH2-CH2-Cl pattern and so a possible treatment of mustard gaz intoxication.
She ended up being in contact with a low dose of one of those mustard "mimic" substrate probably because she didn't wear gloves for a short time. Her hands and cheeks (because she probably touched her face) started to swell, blisters appeared on the exposed area, this was horrible. And it took several days to return to normal.. Now she can't work on those compounds anymore.
That is terrifying
I remember being splattered (?) on in the eye with formaldehyde in an anatomy and physiology class. I was wearing PPE but i guess i didn't wear eye protection properly. It hurt so bad I thought I was going to go blind.
Ha, we used dip cigarettes in it and smoke it when about Jr High.
@@krisreddish3066 formaldehyde cigarettes? xd
@@MrDanielsahne I was told it increases the availability of nicotine. Personally I wouldn't do it,
I'm happy adding a drop of nicotine extract to my cigarettes... boost content a mg or 2..
@@petevenuti7355 It does things to your brain. Caused really odd time loss for me. I mean most of them probably tried the adult version later, but I am allergic to PCP so I never tried wet.
