苯丙胺对铜绿微囊藻的生物效应研究

Study on Biological Effects of Amphetamine on Growth of Microcystis

研究了不同浓度苯丙胺在不同条件下对铜绿微囊藻的生长及毒性效应。结果表明 ,低浓度苯丙胺在弱碱性条件下促进铜绿微囊藻的生长 ;高浓度的苯丙胺则抑制其生长。苯丙胺对铜绿微囊藻 2 4、48、72、96h的EC50 值分别为 2 4 .52、1 6 .51、1 0 .76、9.60mg/L 。

The kinetics process of the effects of Amphetamine(AMP) on the growth of Microcystis at different conditions were investigated. Results indicated that the growth of Microcystics can be prompted at lower concentration in basic condition, and it was inhibited at the higher concentration of AMP. The 24 h, 48 h, 72 h and 96 h EC_(50) of AMP to Microcystics are 24.52 mg/ L,16.51 mg/ L,10.76 mg/ L and 9.60 mg/ L,and toxicity of AMP to Microcystics increased with time.
