title: The influence of dissolved selenium compounds on the accumulation of inorganic and methylated mercury compounds from solution by the mussel Mytilus edulis and the plaice Pleuronectes platessa.
abstract: In laboratory experiments, the effects of dissolved selenate and selenite (2 and 200 micrograms Se l-1) on the accumulation of inorganic and methylated mercury (1 microgram l-1) from solution by mussels (Mytilus edulis) and plaice (Pleuronectes platessa) have been studied. In mussels, selenate, and to a lesser extent selenite, markedly reduced the accumulation of inorganic mercury in gills, mantle, kidney and digestive gland. Selenate at 2 micrograms Se l-1 inhibited methylmercury accumulation in most organs, but the same effect was not observed at 200 micrograms l-1. Selenite had little effect on methylmercury accumulation. In plaice, selenate (2 and 200 micrograms l-1) and selenite (200 micrograms l-1) enhanced the accumulation of inorganic mercury in muscle only, but neither compound had any effect on the accumulation of methylated mercury.
