为考察中国西北地区某县分散式供水中重金属污染现状及其对人体的潜在危害
选取13处水窖和10处水井
采用电感耦合等离子体质谱技术对饮用水中常见的15种重金属元素进行了抽样检测
并借助美国环保局推荐的风险评价模型对重金属引起的健康风险进行了系统评估。结果表明
某县井水中Zn、Al和Cr的质量浓度相对较高
但均不存在超标问题。将井水贮存于水窖一段时间后
除Mn、As和Ni外
大部分元素的平均质量浓度出现不同程度的升高
甚至在3号点出现Cd的超标现象。与井水相比
雨水中的重金属元素质量浓度普遍偏低
在混入自来水后窖水中Al的质量浓度明显偏高。虽然水样中的Cr不存在超标问题
但由其引起的致癌风险超出美国环保局规定的可接受风险上限1×10
-4
且占致癌总风险的90%以上。借助物料衡算法对水样中重金属来源进一步分析
发现采煤场周边井水中98.7%的Cd、81.5%的Cr和61.6%的As源自采煤场的污染排放
焦化厂周边井水中99.2%的Cr源自焦化厂的污染排放
窖水中的Cd和Cr则主要源自水窖材质溶出。
To investigate the pollution status of heavy metals in decentrali-ed water supply in a county in Northwest China and the potential ha-ards to human
13 water cellars and 10 wells were selected. The sampling determination of the 15 common heavy metals in drinking water were carried out by inductively coupled plasma mass spectrometry technology
and the potential health risks of the heavy metal elements were systematically assessed by using the risk assessment model recommended by US EPA. The results show that the mass concentrations of Zn
Al and Cr in underground well water of the county are relatively high
but there is no phenomenon of exceeding the standard. After the well water is stored in the cellar for a period of time
the average mass concentrations of most elements except Mn
As and Ni increase in varying degrees. And even Cd content in no.3 water sample exceeds the standard. Compared with the well water
the mass concentrations of the heavy metals in rainwater are generally
