This study assessed potential human health risks posed by tributyltin in se
afood purchased from U.S. seafood markets. In 1989 and 1990, samples of fis
h, bivalve molluscs and crustacea were purchased at local markets along the
Atlantic, Gulf and Pacific coasts of the United States and along the Great
Lakes (Lake Michigan). Samples were then analyzed for tributyltin, and the
concentrations observed used to evaluate potential human health risks from
consumption of market-bought seafood on the basis of available mammalian t
oxicology data. The assessment indicated health effects were unlikely from
exposure to tributyltin in market-bought seafood during 1989 to 1990, short
ly after peak tributyltin usage in antifoulant bottom paints on vessels in
the United States.
