摘　　要：收集了13种二苯甲酮类紫外防晒剂对3种水生生物(发光菌、大型溞、真涡虫)的毒性数据,建立了生物毒性与辛醇/水分配系数、Abraham参数的相关模型,并分析了二苯甲酮类紫外防晒剂对水生生物的毒性作用机理.同时对Abraham方程的回归系数进行主成分分析,发现了二苯甲酮类紫外防晒剂对3种水生生物的毒性机理具有一定的差异性,通过对3种水生生物种间相关分析发现,物种的种间相关性并不理想,进一步说明其毒性机理存在差异.The toxicity data of 13 benzophenone UV filters to 3 aquatic organisms(P.phosphoreum,D.magna and D.japonica)were collected.The linear relationships between the toxicity data and octanol/water partition coefficient,Abraham parameter were established.The mechanisms of toxic action to 3 aquatic organisms were analyzed.At the same time,the principal component analysis carried out on the regression coefficients of Abraham equations shows that there are interspecies differences.The interspecies correlations of benzophenone UV filters to 3 aquatic organisms were analyzed.The results show that the interspecies correlation is not ideal,further indicating that there are interspecies differences in the mechanisms of toxic.
