摘要
为了解新疆石河子地区地下水重(类)金属污染状况及对人体健康的潜在危害,以22组地下水样品中Fe、Cu、Pb、Zn、Cd、Mn、As、Hg、Cr^(6+)共9种重(类)金属元素为研究对象,通过对比《地下水质量标准》(GB/T 14848—2017),运用内梅罗综合污染指数法和基于三角模糊数理论的健康风险评价模型对重(类)金属污染状况进行了评价。结果表明:Fe、Mn、As为石河子地区地下水中主要超标重(类)金属元素;潜水、浅层承压水、深层承压水均存在不同程度的重(类)金属污染;重(类)金属化学非致癌总风险在允许限度内,重(类)金属化学致癌总风险超过了最大可接受水平;地下水中致癌物质As通过饮水途径对人体健康产生的危害不容忽视。
In order to understand the pollution status of heavy metals(metalloid)in groundwater and its potential harm to human health in Shihezi area of Xinjiang,nine heavy metals(metalloid)elements(Fe,Cu,Pb,Zn,Cd,Mn,As,Hg,Cr^(6+))in 22 groups of groundwater samples were selected as the research objects.By comparing the Standard for Groundwater Quality(GB/T 14848-2017),the comprehensive pollution index method and a health risk assessment model based on triangular fuzzy number theory were used to evaluate the pollution status and its potential harm to human health.The results show that Fe,Mn and As are the main heavy metal(metalloid)elements exceeding the standard in groundwater in the study area.There are different degrees of heavy metal pollution in phreatic,shallow confined water and deep confined water.The total non-carcinogenic risk is within the acceptable range.The total carcinogenic risk has exceeded the maximum acceptable level.This study indicates that the carcinogenic substance As in groundwater is harmful to human health through drinking water.
