英文摘要	以真鲷和平鲷幼体为实验材料，采用联合指数相加法，研究了重金属和农药对真鲷和平鲷幼体的急性毒性和联合毒性效应.实验结果表明：铜、锰、甲胺磷和甲基异柳磷对真鲷和平鲷幼体的毒性顺序是：甲基异柳磷＞锰＞铜＞甲胺磷.甲胺磷和Mn对真鲷和平鲷幼体毒性相同；Cu对2种鱼的毒性几乎相同；而甲基异柳磷对真鲷的96HlC50为0.02Mg/l，对平鲷幼体的96HlC50为0.0014Mg/l，前者是后者的14倍.对真鲷，甲基异柳磷的毒性比甲胺磷毒性大175倍，而对平鲷幼体，甲基异柳磷的毒性比甲胺磷毒性竟大2500倍.联合毒性实验结果表明：铜-锰、铜-甲基异柳磷对真鲷和平鲷幼体的联合毒性为拮抗作用，甲基异柳磷-甲胺磷的联合毒性为协同作用; The additive index of coeFFects was used to study the toxicities of Cu Mn,Cu isofenphos methyl and methamidphos isofenphos methyl on Pagrosomus major and Rhabdosargus sarba. The acute toxicities of the Four pollutants were in the sequence of isofenphos methyl>Mn>Cu>methamidphos.Mn and methamidphos were equivalently toxic to P.major and R.sarba, Cu was almost equivalently toxic to them,while the 96h median lethal concentrations of isofenphos methyl were 0 02mg/L For P.major, and 0.0014mg/L For R.sarba, respectively.The toxicity of isofenphos methyl For P.major was 13 times higher than that For R.sarba. The toxicity of isofenphos methyl were 174 times higher than that of methamidphos For P.major. The toxicity of isofenphos methyl was 2500 times that of methamidphos For R.sarba. The additive toxicity of Cu Mn and Cu isofenphos methyl For two species Fishes was shown to be antagonistic, while that of methamidphos isofenphos methyl was synergism.; 福建省自然科学基金
