Abstract/OtherAbstract:
We conducted an investigation of heavy metal concentrations in Manila clams (Ruditapes philippinarum) and surface sediments after the Dalian Port oil spill. Samples were collected from three mariculture zones (Jinshitan, Dalijia, and Pikou) along the Dalian coast. Heavy metal concentrations in R. philippinarum were consistent and ranked in decreasing order of Zn > Cu > As > Cr > Pb > Cd > Hg, while concentrations in surface sediments were ranked as Zn > Cr > Cu > Pb > As > Cd > Hg, respectively. Bioaccumulation of Zn, Cd, and Hg had obviously occurred in R. philippinarum. Statistically significant correlations (p < 0.05) between concentrations of Pb, Cd, and Hg in R. philippinarum and in surface sediments were observed. Except for Cr and As, heavy metal concentrations in R. philippinarum were well within the legal limits for human consumption.
