Fingerling rainbow trout (Salmo gairdneri Richardson) were used to determine the lethal toxicity of Matacil 1.8 F and Matacil 1.8 D ready-to-use formulations. The 96-h LC50s were 21.3 mg/l for water-based Matacil 1.8 F; 19.1 mg/l for oil-based Matacil 1.8 F; and 0.36 mg/l for Matacil 1.8 D. Aminocarb (4-dimethylamino-m-tolyl N-methylcarbamate) and MA (4-methylamino-m-tolyl N-methylcarbamate) were detected in fish tissue 96 h after exposure. More than 50% of the total residue (Aminocarb + MA) were the parent compound. The bioaccumulation ratio ranged from 1.70 to 3.32 at different concentrations of aminocarb. Both aminocarb and MA were rapidly eliminated after the fish had been transferred to clean water; the total residue declined by more than 90% in 72 h and became non-detectable in 96 h.
使用虹鳟鱼苗(虹鳟,Richardson)来测定Matacil 1.8 F和Matacil 1.8 D即用型制剂的致死毒性。水基Matacil 1.8 F的96小时半数致死浓度(LC50)为21.3毫克/升;油基Matacil 1.8 F为19.1毫克/升;Matacil 1.8 D为0.36毫克/升。暴露96小时后,在鱼组织中检测到灭害威(4-二甲基氨基间甲苯基N-甲基氨基甲酸酯)和MA(4-甲氨基间甲苯基N-甲基氨基甲酸酯)。总残留量(灭害威+MA)的50%以上为母体化合物。在不同浓度的灭害威下,生物累积率在1.70至3.32之间。将鱼转移到清洁水中后,灭害威和MA均迅速消除;总残留量在72小时内下降了90%以上,并在96小时内变得无法检测到。
