Concentrations and human health implications of heavy metals in wild aquatic organisms captured from the core area of Daya Bay's Fishery Resource Reserve, South China Sea.
Heavy metal concentrations in edible organisms from the core area of Daya Bay's Fishery Resource Reserve, South China Sea, were determined. Samples of 14 crustacean, fish, and shellfish species were collected and analyzed. The As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn concentrations were 0.18-1.16, 0.002-0.919, 0.40-2.85, 0.07-4.10, 0.004-0.055, 0.14-1.19, 0.014-0.070, and 4.57-15.94μg/g wet weight, respectively. The As concentrations were higher than the Chinese maximum permissible levels in all of the fish and shellfish species and two crustacean species, indicating that consumption of these wild species by humans may pose health risks. However, calculations of the health risks posed to humans indicated that no significant adverse health effects would be associated with consuming these species.
