摘要: 应用急性毒性实验和生命表实验等方法,研究了邻苯二甲酸二丁酯(dibutyl phthalate, DBP)对淡水枝角类多刺裸腹溞的急性毒性和生命表统计学参数的影响。结果表明,DBP对多刺裸腹溞48 h LC50为9.68 mg·L-1;0.05~5000 μg·L-1的DBP对多刺裸腹溞的生命期望、总生殖率和净生殖率均无显著影响,但对世代时间和种群内禀增长率有显著影响(P<0.05);与对照组相比,5000 μg·L-1的DBP显著缩短了多刺裸腹溞的世代时间,提高了种群内禀增长率。

Abstract: Acute toxicity and life-table experiments were conducted to study the acute toxicity of dibutyl phthalate (DBP) and its effects on the life table demographic parameters of freshwater cladoceran Monia macrocopa. The 48 h LC50 of M. macrocopa for DBP was 968 mg·L-1. DBP at 005〖KG-*2〗-〖KG-*7〗5000 μg·L-1 did not significantly affect the life expectancy at birth and the gross and net reproductive rates, but significantly affected the generation time and intrinsic rate of population increase of M. macrocopa (P<005). Comparing with the control, DBP at 5000 μg·L-1 significantly decreased the generation time, but increased the intrinsic rate of population increase.
