Elliptio complanata

Chau and coworkers133 investigated the bioaccumulation of alkyllead compounds from water and from contaminated sediments by freshwater mussels, Elliptio complanata. Higher levels of trimethyllead than triethyllead species were accumulated after the same exposure period. In vivo transformation of the trialkyllead species by a series of dealkylation reactions giving dialkyllead and inorganic lead(II) species appears to take place. Rates of accumulation are higher for the more contaminated sediments133.

In recognition of enviromnental problems by effluent from fish farms, freshwater mussel, Elliptio complanata, has been used to treat pond water by removing cyanobacterial blooms of Microcystis from aquaculture systems (Stuart et al., 2001). Similar studies have been carried out to treat effluent from shrimp farms and other aquaculture operations.
