摘　　要：在实验室条件下研究了邻苯二甲酸二丁酯对多刺裸腹溞的急性毒性和连续作用四个世代的慢性毒性。研究结果表明:邻苯二甲酸二丁酯对多刺裸腹溞的生长和繁殖具有显著的毒性效应;邻苯二甲酸二丁酯对多刺裸腹溞的24 h半致死浓度为8.44mg·L^(-1);持续暴露在邻苯二甲酸二丁酯下的多刺裸腹溞子一代和子二代受到的伤害最为显著;不同世代多刺裸腹溞对邻苯二甲酸二丁酯具有一定的耐受性,子一代和子二代耐受性下降,敏感性增强,子三代敏感性下降。研究结果有助于了解环境激素类物质对枝角类动物生长和繁殖的长期毒性效应及其规律。The acute toxicity and chronic toxicity of four successive generations of moin macrocopa that exposured in dibutyl phthalate concentrations was studied in laboratory condition .The results showed that the toxic effects of DBP exposure on growth and multiply of miona macrocopa were observed .The LCs0 of DBP to moina macrocop is 8.44mg ~ L-1. The effect of toxicity to moina macrocopa which were exposured in DBP was persistent. It was the notable and the tolerance of exposure in DBP was declined in the generation F1 and F2.The susceptibility was declined in the generation F3.The results can be helpful to understand the long-term toxicity and the law in environmental hormone substances on the growth and reproduction of Cladocera.
