摘要 研究了联苯胺对大型溞(Daphniamagna)的急性毒性和慢性毒性.急性毒性试验结果表明,联苯胺对大型溞的ρLC50, 24h、ρLC50, 48h值分别为 1. 73mgL-1和 0. 89mgL-1. 21d生活周期试验结果表明,大型溞的生殖是对该化合物最为敏感的慢性毒性指标.联苯胺对大型溞生殖的无可见效应浓度(NOEC/Reproduction)为 0. 004mgL-1,最低可见效应浓度(LO EC/Reproduction)为 0. 012mgL-1.并据此计算出该毒物的最大允许浓度(MATC)为 0. 008 9mgL-1. 表 3参 The acute and chronic toxicities of benzidine to Daphnia magna were studied. The ρ LC50,24h,ρ LC50,48h values of benzidine to this species were 1.73 mg L -1 and 0.89 mg L -1, respectively. The results of a 21 d life cycle test showed that the reproduction of D. magna was the most sensitive indicator of chronic toxicity of this chemical. The non-observed effect concentration on reproduction (NOEC/Reproduction) and lowest observed effect concentration on reproduction (LOEC/reproduction) values of benzidine to this species were 0.004 mg L -1 and 0.012 mg L -1, respectively. The maximum acceptable toxicant concentration (MATC) of benzidine to D. magna was 0.008 9 mg L -1, which was estimated by the above two values. Tab 3, Ref 19
