摘  要:
[目的]研究2甲4氯和2甲4氯异辛酯对水生生物的生物富集性。[方法]通过建立2甲4氯和2甲4氯异辛酯在水体和鱼体中残留量的检测方法,采用静态法和半静态法分别研究2甲4氯和2甲4氯异辛酯在斑马鱼体内的富集效应。[结果]鱼体对2甲4氯和2甲4氯异辛酯处理8 d后的生物富集系数BCF值分别为1.61~1.82和16.3~22.3。[结论]根据《化学农药环境安全评价试验准则》农药生物富集性划分等级标准,2甲4氯属于低生物富集性农药,2甲4氯异辛酯属于中等生物富集性农药。

摘  要:
[Aims]The aims were to study the bio-concentration of MCPA and MCPA-isooctyl ester in aquatic organisms.[Methods]The detection methods of MCPA and MCPA-isooctyl ester residues in water and fish were established,the bio-concentration of MCPA and MCPA isooctyl ester in Brachydonio rerio was studied by static and semi-static method.[Results]The bio-concentration factors(BCF,8 d) of MCPA and MCPA-isooctyl ester in B.rerio were 1.61-1.82 and 16.3-22.3,respectively.[Conclusions]According to Test Guidelines on Environmental Safety Assessment for Chemical Pesticides,MCPA was classified as low bio-concentration pesticide,MCPA-isooctyl ester was classified as medium bio-concentration pesticide.
