浙江省某废弃工厂土壤重金属污染特征、风险及来源解析
Characteristics,risk assessment,and source analysis of heavy metal pollution in soil from an abandoned factory in Zhejiang Province
摘要
Abstract
To evaluate the characteristics,risk levels,and source analysis of heavy metal pollution in the soil of the abandoned factory,a factory in Zhejiang Province was selected as a study area to detect the content of Cu,Ni,Zn,Pb,Cd,As and Hg in the soil at different depths.Pollution load index,geo-accumulation index,potential ecological risk assessment and the human health risk assessment model in adult were applied to evaluate the degree of soil heavy metal pollution and risk level.Joint correlation analysis and principal component analysis was used to analyze the sources of soil heavy metal pollution.The results indicate that the study area is mainly non polluted and lightly polluted,and there is a slight ecological risk.Hg and As are the main contributing factors to pollution accumulation,and ecological risk is caused by Hg and Cd.The non carcinogenic and carcinogenic risks of various heavy metal elements are controllable,while As is a major contributor to adult health threats.The sources of soil heavy metal pollution were divided into natural sources and industrial sources,accounting for 49.12%and 15.45%respectively.The results can provide data support and scientific basis for soil pollution prevention and ecological restoration after factory abandonment.关键词
