what are persistent organic pollutant
This term describes the process by which pollutants accumulate in organisms at higher trophic levels.
Biomagnification
Runoff of agricultural waste products are this type of pollutant source.

These are two of the 4 methods to remove oil from water that we discussed.
1. Skimmer boats
2. Chemical treatment / absorbents
3. Burn the oil

Mercury can enter aquatic ecosystems by
combustion of coal releases particulates with mercury attached that can be deposited in downwind aquatic ecosystems by particulates or precipitation, coal ash ponds can overflow which releases mercury into nearby surface water
The loss of wetlands and mangroves can lead to a decrease in this type of biodiversity, which refers to the variety of different species in an ecosystem.
What is species biodiversity?
