四川攀西地区典型金属采选与冶炼企业周边农用地重金属污染评价及来源解析OACSTPCD
Evaluation and Source Analysis of Heavy Metal Pollution in Farmland Soils Around Typical Metal Mining and Smelting Enterprises in Panzhihua-Xichang Area of Sichuan
为了研究采选和冶炼企业周边农用地的污染现状以及形成原因,以四川攀西地区16家相关企业周边农用地为研究对象,采用农用地风险管控标准、内梅罗综合污染指数法等评价了土壤重金属污染现状,并结合相关性分析和主成分分析研究土壤重金属的来源.调查结果表明:严格管控类、安全利用类、优先保护类点位占比分别为30.3％、59.1％和10.6％;内梅罗综合污染指数评价结果为重污染;地质累积污染评价镉＞汞＞锌＞铜＞铅＞铬＞砷＞镍;潜在生态风险指数评价结果轻微、中度、强度…查看全部>>
The farmland around 16 typical mining and smelting enterprises in Panzhihua-Xichang area of Sichuan were taken as the research object,in order to evaluate the pollution situation in this area,and further explore the sources of heavy metals.Risk control standards for soil contamination of agricultural land and Nemerow pollution index were used to assess the pollution situation of the heavy metals,and principal component analysis and correlation analysis were …查看全部>>
