原子荧光法测定中山市地下水汞铅砷元素含量
|
摘要
以中山市地下水为研究对象,在中山市各地区水井和山泉水水源地布点采集地下水样品,检测分析了样品中重金属汞、铅、砷的含量并评价污染风险。结果表明,中山市地下水中汞、铅、砷元素的污染浓度水平尚处于安全可控范围,但是该三种重金属均有较高检出率,尤其是砷元素的污染比较普遍,该地区的地下水具有一定的砷污染生态风险。
Collecting groundwater samples from wells and water source sites of spring water in various regions of Zhongshan City. The content of heavy metal mercury, arsenic and lead in the samples was tested, analyzed. Evaluating the risk of the three heavy metals. The results show that the contamination of mercury,arsenic and lead in shallow groundwater in Zhongshan city is safe and controllable, but the detection rate of three heavy metals is higher, especially arsenic pollution is more common. There was a certain ecological risk of arsenic pollution.
