Tributyltin analyses in association with NOAA's national status and trends mussel watch program Conference Paper uri icon


  • The concentration of butyltins, including tributyltin (TBT), dibutyltin (DBT), and monobutyltin (MBT), were determined in bivalves and sediments from 36 U.S. coastal sites. Bivalves (oysters and mussels) from 97% and sediment from 75% of these sites were contaminated with butyltins. The average bivalve total butyltin concentration (640 ng/g as Sn) was 18 times higher than the average sediment concentration (36 ng/g as Sn). The most toxic butyltin, TBT, accounts on average for 75% in bivalves and 80% in sediments of the total butyltins present. Sediments may be a long-term chronic source of butyltins to estuarine ecosystems even after TBT inputs cease. Temporal concentration changes were found for Gulf of Mexico oysters, but no seasonal trends were apparent.
