%X With recent investigation and historical data the contents of polychlorinated biphenyls (PCBs) in Jinjiang oysters (Crassostrea rivularis) were studied along coast of South China. The results determined by gas chromatography with micro electric capture detector indicated that the contents of PCBs in the oysters were 0.003-0.253mg/kg (wet wt.) in 2006 and 2007, which is below shellfish hygiene standards of China and other major countries. The spatial distribution of PCBs was very uneven place to place in range of 82-1243ng/g (dry wt.) in 2006-2007. The contents of PCBs in dry-weight oysters ranged from 30?041ng/g with average of 171ng/g in 2003-2007, while that of in 1989-1991 was only 0.35-1.43ng/g with average of 0.62ng/g. The mean PCBs content in region from high to low was in the order of East Guangdong coast, Pearl River Estuary and West Guangdong coast during 2003-2007, but Pearl River Estuary, East Guangdong coast and West Guangdong coast during 1989-1991.
