Your explanation is great, thank you 💜

clean and simple!

I was looking for this explanation and suddenly found this ! Thanks you

great explanation..tq so much

Very helpful!! Thank you!!

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.

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!

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!

How do you remove radionuclides from the Pacific ocean?

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

@elleszabo8655

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.

why these pollutants are harmful what are their effects?

I always wonder, how are all the pharmaceutical drugs affecting water and can oxygen and bacteria dissolve them?

@elleszabo8655

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.

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...

Point non point, water

it's insane how we spend billions of dollars trying to discover water on other planets yet we pollute and destroy our very own.
