Note
Molluscs have been identified as sensitive nontarget organisms to tributyltin (TBT) released from antifouling coatings. Special concerns have focused on commercially important bivalves. The purpose of our research was to examine risks of TBT to the hard shell clam, Mercenaria mercenaria, and the oyster, Crassostrea virginica. We were particularly interested in clams because there had been no published information about effects of TBT on them.
