摘　　要：采用现场培养实验的方法,研究了Cu、Pb、Zn和Cd重金属对东海原甲藻(Prorocentrum donghaiense Lu)的生态毒性效应。计算结果表明:重金属Cu、Pb、Zn、Cd对东海原甲藻生长的非观察效应浓度(NOEC)分别为3.7、32.6、133.2和128.0μg/L;生长抑制效应浓度EC05分别为4.6、56.3、142.8和151.3μg/L。估算了我国东海海水中重金属Cu、Pb、Zn和Cd的生态基准浓度分别为4.6、0.1、28和0.3μg/L。我国Cu、Pb和Cd的一类海水水质标准高于东海海水生态基准。The ecotoxicological effects of copper, lead, zinc and cadmium on Prorocentrum donghaiense Lu were studied by means of incubation test in situ. The results showed that the effective concentration of copper, lead, zinc and cadmium on Prorocentrum donghaiense Lu were not found to be 3.7,32.3, 133.2 and 128.0 g/L, and effect concentrations of growth inhibition EC05 were computed to be 4.6, 56.3, 142.8 and 151.3 g/L, respectively. The ecological benchmark concentrations of seawater in East China Sea were estimated to be 4.6, 0.1,28 and 0.3 g/L. The national first class of seawater quality standards for copper, lead and cadmium were higher than ecological criterion concentration of seawater in East China Sea.
