Decomposers typically live on the sea floor and include species like crabs, opossum shrimps, whelks and starfish.[1] They feed primary on decaying organic matter, which can often contain high concentrations of pollutants. [2] This causes decomposers to have a higher pollutant contents than other zoobenthos.
Crabs, especially their larvae, appear to be vulnerable to pesticides [3] This vulnerability caused the crab fishery of Chesapeake Bay in the 1960s collapse due to a pesticide called keptone.
Below you can find some links to Belgian case studies on ecotoxicology in marine scavengers.
Case studies
Case study 1: Flame retardants organotin compounds and surfactants in opossum shrimps of the Scheldt estuary.[4]
Case study 2: Effects of endocrine disrupting compounds on embryonic development of opossum shrimps.G[5]
