Decomposers feed on decaying organic matter, which can ofter contain high concentrations of pollutants. [1] This causes decomposers, like crabs, to have a higher pollutant contents than other zoobenthos.
Crabs, especially larvae, appear to be vulnerable to pesticides [2] So did the crab fishery of Chesapeake Bay in the 1960s collapse due to a pesticide called keptone.
