Abstract : This study better defines the long-term toxicity and bioaccumulation potential of tributyltin released from antifouling paint to marine species. Because of the increasing evidence of the presence of tributyltin in environmental samples, the eastern oyster (Crassostrea virginica), the bay mussel (Mytilus edulis), and the flatfish (Citharichthys stigmaeus) were tested at low and sub-ppb tributyltin concentrations for a 65-67 day chronic test period. Additionally, the hatching success of fish eggs (California grunion, Leuresthes tenuis) exposed to tributyltin and subsequent larval fish survival at low tributyltin concentrations were also tested. Acute toxicity tests (96 hours) were conducted with mysid shrimp (Acanthomysis sculpta) to assess the toxicity of tributylin to this sensitive marine species. The data clearly indicate sublethal growth effects and mortality to some marine species occur at tributyltin concentrations of 1 ppb and less. (Author)
