摘要
采用现场培养实验,研究了铜对中肋骨条藻(Skeletonema costatuma)的生态毒性效应.结果表明,胶州湾内铜抑制中肋骨条藻生长的非观察效应浓度(NOEC)为3.9μg/L,生长抑制效应浓度EC05、EC10和EC50分别为4.8,5.7,9.6μg/L.在分析比较浮游植物常规生态毒性反应终点的敏感性、可靠性及生态学意义的基础上,探讨了logistic生长模型的参数——环境容纳量作为反应终点在生态毒性研究中的应用.现场培养实验与实验室实验的分析比较表明,现场培养实验获得的生长抑制浓度低于实验室获得的数据,铜在实际环境中的毒性更大.
The ecotoxicological effects of copper on Skeletonema costatuma adopting the method of in situ incubation test were studied. The no observed effective concentration （NOEC） of copper inhibition on Skeletonema costatuma growth was 3.9μg/L in Jiaozhou Bay, EC05, EC10 and EC50, the effect concentrations of growth inhibition, were 4.8, 5.7 and 9.6μg/Lrespectively. The application of the parameter of logistic growth model - environmental capacity as end point in the studies of ecotoxicology was probed into based on the analysis and comparison of sensitivity, reliability and ecological signification of ecotoxicological end point of phytoplankton. The analysis comparing of in situ incubation test and laboratory test showed that in situ incubation test obtained growth inhibition concentration was lower than the laboratory obtained data. The toxicity of copper in actual environment was greater seemingly.
