水质型缺水地区地下水重金属污染风险评价OA北大核心CSTPCD
Comprehensive risk assessment on groundwater heavy metal contamination in quality-induced water scarcity regions:case of Jiaxing City
以典型水质型缺水城市嘉兴市作为研究区,采集29 个地下水点位的水样,检测Fe、Mn、Cu、As、Pb、Hg、Cd、Cr的浓度以及pH,采用内梅罗指数法和潜在生态风险指数法评价重金属污染程度,基于地统计分析和数理统计方法分析重金属空间分布特征和来源,并引用风险评估模型量化该污染给居民带来的健康风险.结果表明:①研究区地下水的Fe、Mn、As、Pb含量均值超出Ⅲ类标准的限值,超标率为Fe(86.2%)＞Mn(75.9%)＞As(62.1%)＞Pb(2…查看全部>>
Jiaxing,a city known for its quality-induced water scarcity,was chosen as the research area.Water samples were collected from 29 groundwater points to detect the concentrations of Fe,Mn,Cu,As,Pb,Hg,Cd,Cr,and pH.The Nemerow index and potential ecological risk index methods were employed to evaluate the degree of heavy metal pollution.Spatial distribution characteristics and sources of heavy metals were analyzed using geostatistical analysis and mathematical s…查看全部>>
