Heavy metals 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 are often 10 to 100 times higher than those in solution. The can become biologically available when benthic organisms eat them. [1]


Because correlations exist between metal concentrations in the tissues of organisms and the water and sediments, several estuarine benthic species (seaweed, mussel, brown shrimp,...) have been used as sentinel species for inputs of metals and other pollutants.[1]

TBT nearly caused collaps of oyster farms of Arcachon bay in France[2]

TBT causes imposex in gastropods, which affects female strility. as a consequence many gastropods became locally extinct in the Wadden Sea and the Eastern Scheldt bay. International ban in 2003, remove all TBT by 2008 [3]

Has been shown that due to physico chelical processes metals in soils can become available for uptake. [4]


Case studies

Case study 1: Heavy metal content of mussels in the Western Scheldt estuary[5]

Case study 2: Common starfish can act as a bioindicator for heavy metal pollution[6]

Case study 3: Heavy metals in various Belgian benthic invertebrates[7]

Case study 4: Effects of heavy metals on the sperm quality and the larvae survival of sea urchins[8]

Case study 5: Effects of copper-based antifouling paints on brine shrimp[9]

Case study 6: TBT and intersex in periwinkles[3]

Case study 7: Levels of PCBs and organochlorine pesticides in various benthic species in the Belgian North sea and the Western Scheldt estuary[10]

Case study 8: PCBs and organochlorine pesticides in shrimp from the Belgian North Sea[11]
