The pollutants within Oyster cultured in the coastal water of Shenzhen, Cu、Pb、C、Zn、Ni、total Cr、total Hg、inorganic As and oil were determined from Apr.25th to Aug. 22th of 2002. The contents of pollutants and thebioconcentration ability Oysster on seawater pollutants were analyzed, and quality state of organisms and seawater wereevaluated. The results showed that the pollutants contents in Oyster in Daya Bay were lower than that collected in Shenzhen Bayand the Pearl river estuary.The samples of Daya Bay are eatable in case of adopting reasonable culturing depurative methods,while the samples of Shenzhen Bay and the Pearl river estuary were deeply effected by pollutant.The order of concentrationfactor within Oyster was Zn>Cu>Cd>Pb>total Cr>Ni>total Hg. The concentration factors of Zn、Cu、Cd were more higherthan 1000.
