摘要	To assess the potential toxicity of polycyclic aromatic hydrocarbons and polychlorinated biphenyls on the early development of Meretrix meretrix, the effects of benzo[a]pyrene (Bap) and Aroclor1254 on embryogenesis and larval development were investigated using static laboratory toxicity tests at nominal concentrations of 6.25-1,600 mu g/L. Even at 1,600 mu g/L, Bap and Aroclor1254 only caused minor reductions in embryo development rates. The 96 h LC50 values for D-shaped larvae were 156 mu g/L for Bap and 132 mu g/L for Aroclor1254, respectively. The most sensitive toxicity endpoint in this study was metamorphosis, with an EC50 value of 20 mu g/L for Bap and 35 mu g/L for Aroclor1254. Aroclor1254 was more toxic than Bap to embryos and larvae. Our results indicate that Bap and Aroclor1254 do not show extreme toxicity to M. meretrix embryos and larvae. These data provide information for evaluating the toxicity of Bap and Aroclor1254 on bivalve embryos, especially over the entire larval stages.
