11:41 m/s - This statement is incorrect. The state of Minnesota sued 3M for illegal dumping in waterways throughout the state. Just because you live in say, Bemidji, MN, does not mean your tap water is safe.
You're allowing Google to censor your comments? Shame on you.
I wanted to draw your attention to my comment where I ask permission to use portions of your excellent video in a PSA type media to inform my community. I think the message would be better received if I gave a local history and cut in some entry level information from your video over drone footage of our PFAS generators and the Lamprey River it seems to be seeping into. Most of your video will be too cerebral to begin with but your narrative is very approachable for novices to PFAS , and the credibility of the experts is far more compelling than me reading it off of a page. Thank you for the best video I have watched in this area . Very well done, congratulations.
Dr, Seheult, this is John Pennington 🙏 You know I know how to eradicate these chemicals from the body😁 I'm building a supplement that your going to consume yourself 🙏 Just saying my friend and you have a blessed night 🙏
I can go on and on and on . Dr Seheult, can you do saturation level labs?
I think the companies who developed these, should be held responsible for cleaning up the environment and damage they have caused. Perhaps that would force them to change their actions in the future. This is the same thing on repeat, some company creates some chemicals or has some environmental disaster. They never seem to be liable for their actions. I think the only way to start changing the future for the better and avoid the same thing from happening again, is to start having these companies be financially and legally responsible.
Sadly, they made millions and they've always used money to buy their way out. It would be great if they would clean up their mess. Greedy goes so far as to pollute the mind of men. They're blind to see that it affects every living thing. Including their families.
@@Writer102385 Freeze their bank accts till we see action
I've actually been exposed to the two chemicals. Years ago I visited a great aunt of mine in Sutton. Sutton is two hours away from Parkersburg. I drank water from an old water pump. Never knew about these chemicals until I saw a documentary.
Possibly indicative of the low T caused by these chemicals.
Very little was known about pfas when they first starting using them & the others picked up on it so there's no one company to blame.
These inventors/scientists could have thought of that, that these chemicals don't break down, ahead of time. Instead, they cared about the bottom line. This presentation was excellent. Some of us are born teachers, others not.
Great vid Doc! I'm a ChE and when I saw that they replaced BPA a decade or so ago, I immediately thought "what with? ". At the time I found it was BPB. I got the reverse osmosis dual carbon and resin filter for under my sink and stopped buying so many canned foods as BPA is used in the lining.
Europe has a chemical registration system called REACH. It already banned PFAS and a whole host of other chemicals shipping within and to the EU.
Thank you for this information!
What system do u use for RO? I recently got a distiller and I've been distilling the water I plan to consume. Wondering if distillation gets rid of those chemicals...
@@kittykittysoftpaws You'll also get rid of all minerals. Not sure that's good. Prolonged drinking of distilled water can cause problems. Be smart.
@@ms-jl6dl I'm already addressing that by adding the minerals I want and electrolytes to the water I'm going to drink. I'm smart. 😎
@@kittykittysoftpaws I am trying to figure this out also.
On the whole chemical whack a mole issue: banning a single chemical is bad, it's better to apply analog laws to these bans so similar chemicals get banned along, just like what is done with drugs.
However, the superior policy in terms of protecting the people's health, the precautionary principle should be applied, wirtten in law and enforced upon.
I have a system that can remove the "forever chemical" 100% We havent launched yet but stay tuned!
Like a Council of Testosterone Protections. Yeah that's it..
Have replaced nearly all plastics in my house for metals, woods, glasses, and ceramics... ceramics im half suspicius due to the glazes used but getting there. No non stick crap and so forth.
Sadly its impossible to get entirely rid of plastics but a step there at least...
This has to be consumer driven, make them fail and flop if they keep using them, reward those who dont. No other way around it. Governments are too slow, corrupt, incompetent, or simple have no time or budget to test everything. Best path forward is us taking ownership of it.
With developing technology we can create physical micro/nano structures that mimic a lot of the benefits offered by this chemicals, no longer needing them
Convenince truly is the greatest fall...
what about your controller and toothbrush
@@IPursuePeppers-CTH Controller?
Toothbrush is bamboo, the bristles are some plant fiber material.
computer periferals are pretty much the only plastic things left around, more out of having no choice in the matter.
Might look into metal keycaps and magnesium mouse plate at some point.
Even the mousepad is glass now.
There should be regulation.
Loved how Dr Allen took a drink from a glass while Kyle is showing a water bottle.
Something to think about. Every time you go to a restaurant and ask for water, you're getting unfiltered water which may or may not contain PFAS, along with thousands of other chemicals.
Not unfiltered, just hasnt gone through a secondary form of filtration
Even filtered water is likely to contain a small amount of pfas. It's everywhere. The filters that stop pfas, are probably not used in filtered water production yet.
@@k.h.6991 Yep. It's pretty awful. RFK wants to take fluoride out of water but not for scientific reasons. He's not a scientist. It's about power and what he likes and dislikes. RFK won't touch pfas, however. Industries make too much money and have lobbied Congress for decades to use pfas.
The companies should be held criminally liable for making these chemicals.
They only make them because the public demands conveniences, such as non stick pans, non-stain fabrics, various waterproofs, etc. If you all renounced these conveniences there would be no demand, hence no production. Until the public does this, they are equally criminally liable. Can't have your cake and eat it too.
That's Big Pharma.
Unfortunately the water in the Twin Cities MN is heavily contaminated especially in the east metro. 3M was dumping the stuff all over the place even after they knew it was dangerous.
One of the problems home filters is they go to the landfill. I work at a place that uses pfas because no suitable replacement has been found. We use multi-stage carbon filtration to remove pfas from the water. The spent carbon goes to a hazardous waste landfill, but of course when a household disposes of a filter it's straight to the regular garbage.
Good point. Another reason why we need to stop this at the top.
When you say no suitable replacement. What are they using pfas for? Not so long ago, we did not have any of these chemicals and humans lived perfectly fine.
People are too lazy and wanting too much to make meaningful changes to alternatives. That would mean not buying most anything plastic, it takes an intelligent and willful individual to live in a more natural way, importantly, discipline. I don't see America changing this, I don't see poorer nations changing this either. @@jakec5618
I read a study that there are many pharmaceuticals containing PFAS. Many I have taken myself. It’s quite discouraging.
@@jakec5618 chromium plating. Honestly it's OSHA fault they require a fume suppressant even when you have adequate air removal and a scrubber. There are a couple emerging technologies that will likely remove all pfas, but it will likely take a couple years to scale the technology up.
Yet another eye opening video Doc and one that I will be sending to as many family & friends as I can! Thanks for keeping us informed about toxic substances and other important medical topics! 👍👍
Watch dark waters!
You can’t avoid them, they end up in meat all the time, especially fish. Being sick is an American industry.
Please try to organize an interview with Dr. Shanna Swan regarding the developmental toxicity of these forever chemicals.
Thanks
Unfortunately technology’s ever-uncovered concealed harm outweighs its proclaimed benefits. Thanks for an-as usual-elegant, scientific, and eloquent talk.
Thank everyone in these projects pressing every company they can ❣️
I'm so glad I got an under-sink reverse osmosis system a couple years ago. I dont know if my experience is the same but i find it more cost effective than other options.
We should also consider the food we eat that has an added water like canned soups milk is also diluted and all other liquids that you buy in the supermarket including sodas, soft drinks, etc. etc. I’m sure that’s a source also because we don’t know how much filtration used or what’s the quality of it before they add the water.
This is the best video I've come across this topic so far.
It sounds like we are doomed to suffer from the effects of these chemicals for ever. Car upholstery, our clothing and the pans we cook have been bathed in this stuff for decades. It’s no wonder that cancer rates are so high.
The human species is doomed
Does this mean we should go back to glass and metal drinking vessels? If so, which is best, stainless steel?
"Ceramic" Material
Go back to? What were you using?
@@Wes-Tyler "glass or metal"
Porcelain?
@@Wes-Tyler
Plastic?
Very informative. Love your channel and content Dr. Seheult and Dr. Kyle. ❤️🙏
Yes, we all should read lebels and fully understand the ingredients or chemicals in your food, clothing, water, etc. If there are no ingredients or chemicals listed on the products that is a red flag.
Drink from glass, who cares if your clothes stain, and scrub your iron skillet. That will help, but must hold company and EPA feet to the fire. Consumer protection has been eroded in this country.
We have a plastic straw ban in my state. (Why was it so hard to get that passed?)
Some fast food places will fill your own cup if you bring it, rather than giving you a plastic cup. A few even sell metal cups with their logo, and give you your first drink from it free, plus a discount in the future if you offer your own cup with their logo.
Great video! One important question for you. How do we detox from these chemicals?
We dont..
They are forever
@@miss.behaving That's what they say, for convenience, but there is always a way, we just have to find it.
@@ImYourHuckleberry205
You're correct! Its hard sometimes to not feel/get lost in the doom & gloom of so many oversights that cause so many such turmoil!
But you are correct! We must come together to find these new methods! 🙏
@@miss.behaving so they pretty much gave us the hiv virus of chemicals because everyone in America prettty much has pafas in there blood
@@ImYourHuckleberry205
Do you believe scientists are lying for “convenience” and these are not really forever chemicals?
Good job, this is an important topic. Prevention of contamination, while ideal, seems to be all but impossible. What options exist for detoxification?
Wait for 1,000 years?
This stuff is very prevalent in fast food wrappings.
Thankfully some have switched away. BK and McD for example. Now if people could switch away from fast food we’d be getting some progress.
As usual, superb presentation and invaluable info. Thank you
I feel vindicated. I had an allergic reaction to a new car I bought back in the mid-2000's and have been a chemical fearing crackpot all by myself for such a long time. Now the question is, how can I convince my wife to stop buying and using nonstick pans!? Her actual stance is "we're all going to die anyway so what does it matter"... mindblowing.
Get her a couple nice carbon steel pans (very light compared to cast-iron, but the seasoning principle is the same), and try to wean her off non-stick by only keeping one pan around for perfect eggs or something.
A couple of questions spring to mind. 1. What harmful chemicals may we end up finding in the RO filters? How ironic would it be if the cure also was harmful?
2. Does distilling remove these chemicals? That would be a process that would be feasible if not super convenient.
I think it is high time that we make lifestyle choices to eliminate as much plastic and synthetic materials as possible from our lives. If we can get pickle relish in glass containers go that way etc. Time for cast iron to make a comeback.
I was also wondering about the RO filters. It seems to be me that g.ovt(andBiigFarma) always find a away to sabotage something that is suppose to be good for us.
I work in the environmental research field and have projects looking at PFAS removal from water.
Citing "99.9% removal" by various home water systems is moot when the EPA is calling for drinking water limits of 4 parts per QUADRILLION (let alone when they say "no safe level")... NO treatment can achieve these limits, and even measuring these concentrations in a routine manner is near impossible
I would greatly appreciate documents (PDFs or links) about the specific toxicities of firefighting foams containing PFAS.
Did you ever receive those links or pdfs?
May I suggest a stainless steel percolator to those who brew coffee in the morning. No plastic parts.
But water with pfas.
No you crossed the line with that
Thank you Medcram, Dr. Seheult, and Kyle for continuing to educate us and the medical people around the world🔥❤️🔥
the largest areas that are for surly known to have extreme concentrations of these toxins can be and will be found around military bases both active and closed down. sadly though there's not much said about this fact other than mentions at times. Instead the companies and EPA will say its the chemical companies that are to blame largely when they've known for awhile now that the bases are a major source as well.
Under the Toxic Substances Cleanup Act adopted in the 1970s, PCBs were banned from manufacture, new use, transport, etc. This included the entire class of PCBs and not just certain ones. While TSCA has its problems, it worked. Maybe our Congress should put forth a new law to ban these classes of chemicals in the same way TSCA did.
Than why cant regulatory bodies classified substance like BPA or BPS or BPF...etc under a general Bisphenol group rather than allowing mutations of this substances to go unregulated?
I thought of that too. But there’s so many combinations how would you know when that sub group ends and another begins. You’d have to define it.
PFAS is detected around the world, at high concentrations in rainwater and sea spray.
Excellent presentation! Thank you.
Wack-a-mole with bisphenyls has been so much fun. The use of these chemicals in food containers (cans, tupperware, etc.) I think is significant. So the new TSCA legislation has not shifted some of the burden testing to industry?
You mean the "Frank R. Lautenberg Chemical Safety for the 21st Century Act"?
This issue should reach its popularity and I think ...
I have to admit some of this is initially over my head, although I’m trying to learn the language of medical studies as I learn the content inside. As a plumber in an industry where POU filters are becoming more common and who wants to be able to inform his clients on the most safe practices, what would be an good alternative to plastic water bottles, BPA, S, etc. free or not?
Thank you so much Doctor, and all those who help produce these videos. What a priceless service you are providing.
Doctors are fictional. Why would you lie about a human slave? (Are you being kept as a slave?)
Every single chemical needs to be tested by numerous third party safety agencies long before it's allowed in the market. If any chemical gets onto the market causes harm to people, water, animals or the environment the company responsible should be shut down indefinitely.
I live in NC and have upholstered for 27 years. I'm now concerned about how much of these chemicals are in my body.
The bonds are Carbon-Fluorine not Carbon-Fluoride.Fluoride is an ionic substance with a -ve charge.
Thank you
You also need to check the level of detection being used by the lab.
I am currently doing active research on PFAS leachate from a source and it's something we need to seal onsite
Excellent information and presentation. Thank you.
In late April, researchers at the University of Texas at Austin announced Thursday that they had used artificial intelligence to successfully engineer a type of enzyme, called a hydrolase, that can break down PET plastic into its component molecules. I wonder if the same or another enzyme could break these down.
Also, when the Exxon Valdez accident occurred, a bacteria discovered in the Hudson River near N.Y.C., was used successfully to break down crude oil with no negative known effects. Curious if they or other bacteria could break down these forever chemicals.
I would confirm that the perfluorocarbon chains are exceptionally inert, and they can be only destroyed by high heat. But it doesn't remove all that fluorine. To do so, we need to burn it with a metal (e.g. magnesium). The perfluoroalkyl substances act as an oxidizer, and we end up with metal fluorides and magnesium. For this reason, PTFE is actually an oxidizer used in some forms of flash photography.
The deep life or bacteria in oil uses arsenic instead of phosphate to join the base pairs together on the DNA backbone . Also there will almost certainly be radioisotopes in oil as there are in fracking.
This is excellent information, may I use portions to help inform my community? We have an emergent PFAS issue that has been flying under the radar and it is past time to make folks aware . Jim McLeod Raymond , NH . Water Planning Committee, Chair Raymond d Planning Board, member.
Sure. May use!
@@Medcram Thank you, that’s brilliant!
What about synthetic MRNA?
I first heard of these compounds from the Institute of Functional Medicine years ago. I remember hearing about POPs- persistent organic pollutants, which are a class of "forever chemicals". What's scary is that some can be passed through breast milk to the next generation.
Proof stop spreading misinformation like god you’re such a Debbie downer
These are great informative videos. Is there one on glyphosate? There seems to be no regulation on how much enters our food system. Crops are doused with it right before harvest. What kind of disease could this be contributing to? Lymphoma or digestive issues? It seems that every other person is suffering from digestive issues and a depleted microbiome. Thank you.
Thank you for sharing such important information!
Our city water department installed a large tank next to the well that apparently filters out some chemicals. This may include some of the chemicals mentioned. I'm thinking about getting a RO filter for my drinking water.
Professor Seheult, your going to be impressed with me sir
Please- a video on immunosenescnce vs spike protein w/or w/o vaccines
Excellent talk thanks. I live in the EU but know the US very well having lived and worked their for a while. This whack-a-mole game played between the regulators and manufacturers in the US illustrates the difference between the fundamental attitude of the EU regulatory system and the US system. In the EU a company must prove a chemical is safe before it can be used whereas in the US its the other way round - if something is 'Generally Regarded As Safe' (GRAS) as stated by the company ...then it can be used until its proven unsafe and its not the responsibility of the manufacturer to check this.
We see it very graphically in the market for supplements ('Nutraceuticals') which is the US is essentially unregulated by an Act of Congress pushed through by lobbyists so in the US its now a 50 billion a year (2021) market in the US whereas cross the border into Canada and you find that supplements (and what the manufacturers claim they do) are tightly regulated. and the same in the EU.
One of the ongoing fights between the US and EU (and between the US & Canada) is that the US considers these regulations as 'unfair barriers to US companies' trying to export. Fortunately the EU is a big market and quite able to tell the US to step off.
We have a lot of criminals in the Government over here.
Excellent report.
Great video for general education purpose
All these chemicals/compounds are relatively modern inventions. Humans lived perfectly fine before developing these. Profit is starting to become more important than human health and nature. Very short sighted thinking. It's time that these corporations who develop such products are held accountable. Far too often, they create these, know very well the dangers of these, and yet still legally pump these out. And then they just get bailed out by the government. People used to live more harmoniously with nature. We need to start valuing our health more, our greatest asset and and most valuable wealth.
Oh if Americans would stop eating slop and research what is going into their mouths…. Won’t happen
GenX: Hexafluoropropylene oxide dimer acid 4:35
Thanks for this post.
I am a ChemE and MD , always worried about thousands these chemicals , sometime in the food chain, sometime in the trash or environments, may be time to think about global effort to clean up or find good alternatives, before we get to point of no return. Starting to put these research ahead of“ global warming” is good direction.
Well, soon global warming will mean these chemicals have no one left they can make sick, cause we’ll all be dead. It doesn’t matter what we put ahead of what.
My question is: If you eliminate these substances, can the body eventually clear them after many years, thus gradually reducing the accumulated health risks? The reduced blood levels seems to imply this? But can they be stored in fat and organs etc?
Just check out the half life lol
this is the topic of my thesis
What is the water filter you mentioned that filtered PFOAS? Thank you
What containers for storing water and food are safe? Is glass safe? How about stainless steel?
Yes. Both glass and stainless steel is free of these compounds.
Can u do a video on cigarettes and cancer then relate to this video? Thank u for what u do.
Another good one! Thank you Dr.
Done at 4:11. Just more industry waste products turn in to money. Thanks you explain well the structures.
This sounds worse than covid! 😳
Awesome! Thank you!
Thats it! God, im ready. Fr..this is just insane
Home Builders nowadays use soft plastic water piping. What is the best way to remove the BPA, and the family of forever chemicals for the water supply within the house?
I wonder if these forever chemicals are the reason why Dr Rhonda Patrick found Finland people live longer and healthier lives with sauna. She said it activated heat proteins but maybe there is more than one reason
It’s so sick that governments don’t ban non stick cookware and anything else where non stick is useless
I'm waiting on my LLC professor Seheult
Wow dude thank you! Big ups my enviro teacher taught a bit abt this but they are nasty stuff
As a good dumb driller ;) who drills all types of wells everyday of his life ...including having to retrieve pfass ground samples everyday of his hard life . This stuff is everywhere and I now have good job security thank you God . 🤠😎
I grew up in Brunswick County and lived there for over 20 years. where are my genx side effects?
INCORRECT! They are regulated now and have indeed been proven to be direct causes. This was legally changed in 2024, so he's actually 100% correct at the time of recording, but of course like we talked about above that changed
The Australian Government should stop these chemicals being used in Australia if they really care about sustainability and Australian citizens exposed to them, costing Australia billions of dollars to clean up, composations, hospital treatments and the loss of Australian lives.
what a great lecture to watch as I enjoy my processed foods cooked with nonstick plastic pan, Simply orange juice, and bottled tap water
What about using non-stick pans where the surface is deteriorating? There is no warning label on the pans.
That's not intended. However, ceramic non-stick layers are generally a safer alternative, as long as the ceramic doesn't contain heavy metals. That can be checked with X-ray spectrometry or LA-ICP-MS (a mass spec system that measured metals on surfaces, minimally destructive and highly sensitive).
Ceramic will deteriorate in a long run.
From my own experience, using one has been more convenient compared to non-stick based on polymers, which deteriorates overtime
I bought a pan that was labeled as "ceramic" then I noticed the coating was peeling and looked just like when Teflon peels....so I got rid of it and now I just cook on stainless steel. Also my instapot came with a coated bowl and I bought a stainless steel one to replace it.
I was reading a research paper from PubMed from 2010 which stated that there was a decrease in the median ng/mL but that was due to the increase in people testing their blood for “forever chemicals”, was that the same paper you used as a reference?
Forever young
Can we use its to make the fibers?
Do you have anything in shower filters? They are going to be in our food as well.
How do we help our bodies🥲
Better living through cancer
finally this year eu reach and usa epa made the regulations to monitor pfas and till 2030s most countries in Europe wanna be zero pfas , will see if we can live till then, so the monitoring and the detection of these pfas forever chemicals is more and more important
The question is, how do we combat bad science? We live in an environment that has severe consequences for questioning bad science.
Are any of these forever chemicals in pex tubing?
No.
what about PTFE?
Iluminating.
Why is distilling hardly ever mentioned? Some of us poor peeps distill our water to remove toxins. I found conflicting info on it removing PFAS however.
That's the reason why Echa works to restrict a entire group of Bisphenols with related derivat right know.
On the study on RO filters, how well would a 5 stage filter system, which includes activated carbon and RO systems perform?
Has anyone explored whether these PFAs can lead to psychosis and possible auditory hallucinations / intrusive thoughts? I am just curious whether this has been researched. With the recent increase in mental health issues, I can't help but to wonder if the two are linked.
DOES PFAS LEAK FROM PAN OR DOES EXPOSERY NEARLY ONLY COME FROM WATER? What about stratched pans?
We are very careful in our consumption. We use a water distiller and the source is city water. We test for particles with an Amazon water tester. It usually has 1 to 4 particles compared to 0 with bottled distilled water from grocery. Would you recommend we continue or try something else. Our made distilled wated makes coffee, tea, drinking water, and anything used in the cooking process. We are also concerned about nanoplastics. Please respond. Thanks
We also did a video on nano plastics too.
