我国水源水及饮用水中微囊藻毒素的污染现状及影响因素研究

Current Status of Microcystin Contamination in Source Water and Finished Water and its Environmental Factors in China

微囊藻毒素是地表水中常见的藻毒素,广泛分布于全世界各种类型的水域。目前已知微囊藻毒素-LR具有极强的肝毒性,达到极低浓度即可对人体健康造成严重危害,因此对于集中式供水水源地正遭受微囊藻毒素污染的报道尤为引人关注。本文综述了近年来关于我国水源水及出厂水中微囊藻毒素的污染现状及与疾病的关系,探讨了微囊藻毒素浓度变化的相关影响因素,为加强对水源水及饮用水中微囊藻毒素的监测和治理,保护人民群众的身心健康提供科学的依据。

Microcystin（MC） is a common algal toxin in surface water and distributed widely in various types of water all around the world. It has confirmed that microcystin-LR did great harm to liver in human even under extremely low concentration. The contamination of Microcystin in source water and finished water has got increasing attraction. The current situation of microcystin contamination in source water and finished water in China and the correlation between MC and diseases was reviewed in this paper; the relationship of MC with environmental factors was also discussed,in order to provide constructive suggestions for monitoring and control of microcystin contamination in source water and finished water.
