Benthic communities are particularly vulnerable to pollutants because they have very limited mobility. [1] Contaminants are usually associated to particles. These particles are often very small, and can therefore stay in solution for a very long time. Nevertheless, concentrations of heavy metals in the soil are often 10 to 100 times higher than those in solution. They can become biologically available when benthic organisms eat them. [2] Metals in soils can also become more available for uptake by zoobenthos due to changing physico chemical processes. [3] Because of their limited mobility, benthic communities are of special interest for monitoring pollutants. Changing concentrations of pollutants in zoobenthos typically reflect changes in the local environment. This is because, although zoobenthos acquire pollutants through food, most of the pollutants contaminate the animals directly; they are adsorbed to its tissue while the animal acquires oxygen. Particularly mussels (the mussel watch program) have been widely used as a bioindicator to detect trends in pollutant concentrations. [2]

TBT

Many zoobenthos species have been effected by the extensive use of TBT in antifouling paints. Because TBT can seriously affect their reproduction, its use nearly caused the collapse of oyster farms of Arcachon bay in France in the 1970s. [4] In gastropods, TBT is known to cause imposex; the presence of male reproductive organs in females, which causes female sterility. These effects caused many gastropod species to became locally extinct in the Wadden Sea and the Eastern Scheldt bay. Eventually this resulted in an international ban to apply TBT on ships starting from 2003, and the obligation to remove all TBT on ships by 2008. [5] [6]

Below you can find some links to Belgian case studies on ecotoxicology in zoobenthos.
