This was incredibly helpful! well spoken and put together. incredible work sir. Thank you for this! very helpful for my course work. I got almost all of them right at the end when i paused the video!
Dear sir, I didn't understand the last point i.e. "The big problem with this is that we are removing the water upstream and dropping sewer downstream but then there is going to be another city just down the way." Please elucidate!
wouldn't it be possible to take advantage of the nitrification / nitrification ( alga bloom ) by harvesting alga and press it into pellets - as poultry feed / OR , plant kelb forests ( other see weed ) at our coast line - and also use it as animal feed , or fertilizer on our farms ?
Actually some are taking advantage of algae to create biofuels. Even though I'm not sure if you could use algae growing in conditions like eutrophic oceans, there are algae farms that create a source of energy. Algae are very inexpensive to cultivate, and the combustion of the resulting biofuel releases no net carbon dioxide.
At 3:14 you said the BOD measures how much oxygen is "produced" by the decomposers; I think it should be how much oxygen is consumed...Great video though!

The main effect of pharmaceutical drugs is that they are endocrine disruptors. That means that the natural sex hormones in organisms such as frogs get out of balance. Males can develop female anatomy and therefore be unable to reproduce. Pharmaceuticals don't affect humans as much since our hormone levels require more to disrupt our endocrine system, but they do affect small animals.
Paul, I don't understand why the O2 increases in polluted water (healthy = 1mg/L vs. EU polluted = 600mg/L) if the bacteria require and is using oxygen thus depleting it from water? Example - eutrophication is oxygen depletion from bacteria consuming dead algae
This comment is very old and I'm not paul, but to answer your question, the oxygen doesn't increase. The oxygen *demand* increases. When he's talking about the measure of BOD increasing, he's describing the amount of oxygen that the water's organisms require. A high number results in less oxygen available in the water after the decomposition process.
I hate edpuzzle. I hate I can not skip around and forces me to rewatch a whole fucking hour of the same shit in loops and ask a specific question of the tiniest section of the video!!!! This is why i rely on the youtube video cause i can skip around to look for the asnwer to save time. Honestly...
jesus is coming soon. jesus is only savior and judge Look at the crossmoon in my clips Psalms 50chapter 15. And call upon me in the day of trouble: I will deliver thee, and thou shalt glorify me.

Please continue with your videos, they are extremely helpful, especially as I have my exams coming up! Thank you.
Love your videos for AP Environmental Science! Thank you.
your video was pretty helpful, thanks for taking the time to make it
you are my inspiration sir...u r great....best teacher of world
Great videos, extremely well done.
Good job!
This was great! Perfect crash course in water pollution

All has to do with poop on top, and how articulate your country is.

Thanks a lot I am a new Science teacher and It is very helpful for me to explain as you do. Blessings!
Very helpful! Thanks
The albatross was the saddest.
Don't try to convince me otherwise.
At 3:14 you said the BOD measures how much oxygen is "produced" by the decomposers; I think it should be how much oxygen is consumed...Great video though!
In the very next sentence, professor clarifies it by saying "dissolved oxygen USED per liter for 5 days at around room temperature"
Outro game weak but good video

Water had to be clean, now a dual work, clean already contaminated and stop adding onward. Let's talk more on it
I always wonder, how are all the pharmaceutical drugs affecting water and can oxygen and bacteria dissolve them?

Wow it is so nice
why these pollutants are harmful what are their effects?
"water polluion"
it's insane how we spend billions of dollars trying to discover water on other planets yet we pollute and destroy our very own.
that was helpful
