微囊藻毒素-LR对大乳头水螅的急性毒性研究
Study on the Acute Toxicity of Microsystin-LR on Hydra magnipapillata
摘要
Abstract
[Objective] The research aimed to evaluate the toxic effect of microcystin on hydroid (aquatic animal model). [Method] Hydra magnipapillata was the test material. Under the different concentrations of MC-LR solution, its acute toxicity on Hydra magnipapillata was observed. [Result] The half lethal concentration {LC50) of MC-LR on Hydra magnipapillata at 24 h was 12. 158 mg/L, 4.029 mg/L at 48 h and 1.799 mg/L at 72 h. [ Conclusion] Hydra magnipapillnla would die when treated with the low concentration of MC-LR solution. It illustrated that MC-LR produced by cyanobacteria bloom caused the damage on some aquatic animals, and even some low-level aquatic animals died, such as Hydra magnipapillata and so on. The research provided some reference basis for the detection and assessment of water body pollution.关键词
