铜绿微囊藻荧光对HgCl2生物毒性响应规律的研究
Study on Response Rule of Microcystis aeruginosa Fluorescence on the Biological Toxicity of HgCl2
摘要
Abstract
[Objective] The research aimed to study response rule of Af. aerugirwsa fluorescence on the biological toxicity of HgCl2. [Method] M. aeruginosa as material, fluorescence intensity at its best launch and emission wavelength as measured indicator, influence of the HgCl2 at different mass concentrations on M. aeruginosa fluorescence intensity was discussed initially. [Result] HgCl2 at different mass concentrations had different influences on M. aeruginosa. Low concentration (0. 002 - 0. 004 mg/L) of HgCl2 could promote photosynthesis of M. aeruginosa. It showed as fluorescence value of the algae liquid becoming smaller. 0. 010 - 0. 400 mg/L of HgCl2 inhibited photosynthesis of M. aeruginosa. It showed as fluorescence value of the algae liquid becoming bigger. Moreover, inhibition effect increased as HgCl2 concentration rose, showing a positive correlation between HgCl2 concentration and toxicity (R2 =0.963 5). [Conclusion] The research provided new theoretical basis for quickly measuring water toxicity.关键词
