缺水重污染河流可溶性金属Cd水质基准研究

摘要

The Water Quality Criteria (WQC) for freshwater soluble metal Cd with the characteristics of environmental endocrine disrupting chemicals of Weihe River in Shaanxi Province were studied using parameters and formulas of fresh water soluble metallic quality criteria made by USEPA, biological effect correction and the method of comparative analysis. The research results indicated that 0.000 7 mg/L (0.7 μg/L) can be used as the WQC recommended value of freshwater soluble metal Cd of Weihe River in Shaanxi Province. The Water Quality Criteria recommended value can provide scientific technical data reference for making local water quality standards of freshwater soluble metal Cd of Weihe River in Shaanxi Province.%以渭河陕西段作为研究对象,采用USEPA制定的淡水可溶性金属基准计算参数与公式、生物效应校正以及对比分析等方法,对渭河陕西段中具有环境内分泌干扰物特性的可溶性金属镉(Cd)的水质基准(WQC)进行了研究.研究结果认为可将0.000 7 mg/L(0.7 μg/L)作为渭河陕西段淡水可溶性金属Cd的基准推荐值,该基准推荐值可对渭河陕西段中可溶性金属Cd的地方水质标准制定提供科学的技术数据参考.
