摘要
微囊藻毒素是某些有毒蓝藻水华发生过程中释放的主要次级代谢产物。该毒素是一组环状七肽,具有多种异构体。研究表明水体中一定浓度的微囊藻毒素对水生动物的卵、生长发育等都有较大的影响,本文综述了微囊藻毒素对鱼类、大型溞等水生动物的毒性效应。
Microcystins is a class of monocyclic heptapeptides with many different isomerides. This toxin is the main secondary metabolites produced by harmful algal bloom. It has been proved that microcystins can influence spawn and growth of aquatic animals in a proper concentration. In this paper, the toxicity of microcystins on aquatic animals,such as fishes and Daphnia magna HB is reviewed.
