S. Kanatireklap et al., CONTAMINATION BY BUTYLTIN COMPOUNDS AND ORGANOCHLORINE RESIDUES IN GREEN MUSSEL (PERNA-VIRIDIS, L.) FROM THAILAND COASTAL WATERS, Environmental pollution, 97(1-2), 1997, pp. 79-89
In order to elucidate marine pollution by butyltins and organochlorine
residues in coastal waters of Thailand, green mussels (Perna viridis)
were collected in 1994 and 1995 and analyzed. Butyltin compounds, suc
h as tributyltin (TBT), dibutyltin (DBT) and monobutyltin (MET), were
detected in most mussel samples, ranging from 4 to 800 ng g(-1) wet wt
(as total). The composition of butyltin derivatives in green mussel w
as in the order of TBT > DBT > MBT. The results indicated that butylti
n contamination was widespread, particularly in high boating areas and
in coastal aquaculture facilities. Concentrations of organochlorine r
esidues were much lower than of butyltin compounds. Among organochlori
ne residues examined, dichlorodiphenyltrichloroethane compounds (DDTs)
were found to be the highest, followed by polychlorinated biphenyls (
PCBs) > chlordane compounds (CHLs) > hexachlorocyclohexanes (HCHs) > h
exachlorobenzene (HCB). To our knowledge, this is a first report on th
e detection of butyltin residues in Thailand coastal waters. (C) 1997
