Accumulation of butyltin compounds in cobia Rachycentron canadum raised in offshore aquaculture sites.

Butyltin residues (monobutyltin, MBT; dibutyltin, DBT; tributyltin, TBT; tetrabutyltin, TeBT) in the sea water and in the cobia (Rachycentron canadum) from aquaculture sites located offshore of Penhu island, Taiwan, were collected and quantified. The average concentrations of MBT, DBT, TBT and TeBT in sea water were n.d.

Accumulation of organotin compounds in Pacific oysters, Crassostrea gigas, collected from aquaculture sites in Taiwan.

Butyltin and phenyltin residues were quantified in Pacific oysters (Crassostrea gigas), which were collected from several aquaculture sites along the west coast of Taiwan during different seasons. Butyltin compounds were detected in all of the samples, except in the oysters collected from the Wanggung site in November 2002. Monophenyltin and diphenyltin compounds were not detected in any of the samples.
