钼对多刺裸腹溞的毒性
Toxicity of molybdenum to cladoceran Moina macrocopa
摘要
Abstract
By means of acute toxicity and life-table experiments, this paper studied the acute tox-icity of molybdenum ( Mo) to Moina macrocopa and the effects of Mo on the life-table demographic parameters of M. Macrocopa. The 48 h LC50 of M. Macrocopa for Mo was 134. 46 mg ? L-1, with the 95% confidence interval of 107. 05-194. 53 mg ? L-1. At concentrations of 2. 0-15. 0 mg ? L-1, Mo had no significant effects on the life expectancy at birth, generation time, average life span, and net reproduction rate, but affected the intrinsic rate of M. Macrocopa population increase significantly. In the control, the intrinsic rate of M. Macrocopa population increase was 0.0448±0.0033 h-1, which was higher than that when the M. Macrocopa was exposed to 6.4, 8.4, 11.2, and 15.0 mg ? L-1 of Mo (0. 0334±0. 0007, 0. 0327±0. 0010, 0. 0335±0. 0003, and 0. 0346±0. 0005 h-1, respectively). Compared with other test organisms, M. Macrocopa was more sensitive to Mo, and among all the life-table demographic parameters, the intrinsic rate of population increase was the most sensitive.关键词
