The bioconcentration of alkyllead compounds from water and from contaminated sediments by freshwater mussels ( Elliptio complanata ) has been investigated. Higher levels of trimethyllead than triethyllead species are accumulated for 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 sediments.
