Question

question 17 0.5 pts why are bfrs so toxic to the ecosystem? they are found at very high concentrations at every food chain level they are resistant to biodegradation and accumulate up the food chain they are toxic to all organs and organ systems question 18 0.5 pts why doesnt the american public see or come in contact with the toxic by - products of and wastes from industrial production? most of the toxic compounds are recycled and never make it out of the system there are not a lot of toxic compounds produced most of the toxic compounds are treated and managed on site and out of the public eye most of the toxic compounds are shipped off to other countries

Explanation:

For Question 17, brominated flame - retardants (BFRs) are toxic to the ecosystem mainly because they resist biodegradation and accumulate up the food chain, leading to higher concentrations in higher - level organisms. For Question 18, the American public doesn't see or come in contact with industrial toxic by - products and wastes because most of these toxic compounds are treated and managed on site away from public view.

Answer:

Question 17: They are resistant to biodegradation and accumulate up the food chain
Question 18: Most of the toxic compounds are treated and managed on site and out of the public eye
