摘要
铜、锌是生命体必需的微量元素,但超过一定的量会对生物产生毒害作用。近年来的研究表明:在中国的一些典型流域水体中,铜、锌相对于其他有毒重金属存在较高的生态风险,主要是因为我国铜、锌的生产量与消费量较高,导致其在部分地表水环境中的浓度较高;同时,水生生物对铜、锌的敏感性远大于人体的敏感性,从而导致其对水生生物存在较高的生态风险。基于此,提出对流域水环境中铜、锌的污染应采取针对性的风险管控措施,以保护水生态系统安全。
Copper(Cu)and zinc(Zn)are essential trace elements in living organisms,but their content more than a certain value will also have a toxic effect on the organism.Recent studies have shown that Cu and Zn have higher risks relative to other heavy metals in surface waters and sediments in some typical watersheds in China,mainly because of the high production and consumption of Cu and Zn in China.The concentrations of Cu and Zn in some surface water environment are high,and also because of the high sensitivity of Cu and Zn to aquatic organisms,resulting a considerable ecological risk.Based on that,it is proposed to adopt targeted risk management and control measures for the pollution of Cu and Zn in the water environment of the river basin,to protect the safety of the water ecosystem.
