霍邱矿山企业地下水重金属污染评价

Evaluation of Heavy Metal Pollution in Groundwater of Huoqiu Mining Enterprise

为了解安徽省六安市北部霍邱矿山企业地下水重金属污染对人类健康产生危害,采集39个地下水样品,测试分析了铜、锰、镍、锌、铅、铁、镉和铝八种重金属。利用单因子指数法对检测结果进行评价:(1)霍邱矿山企业地下水中锰和铅超标率依次为51.28%和17.95%;(2)单项污染指数最大元素为锰,其值为26.7。通过测试评估霍邱县矿山企业浅层地下水质量,重金属含量较高。

In order to understand the risk of groundwater heavy metal pollution to human health in Huoqiu mining enterprise in the north of Lu’an City,Anhui Province,39 groundwater samples were collected and physicochemical analysis were carried out.Nine heavy metals(Cu,Mn,Ni,Zn,Pb,Fe,Na,CD and al)were analyzed.The results were evaluated by single factor index method.The results show that:(1)The over standard rates of manganese,sodium and lead in groundwater of Huoqiu mining enterprises were 51.28%,2.56%and 17.95%respectively;(2)The element with the largest single pollution index is manganese,which is 26.7.Therefore,through the research and evaluation of the shallow groundwater quality of mining enterprises in Huoqiu County,it is found that the content of heavy metals is high.
