陕西省典型矿区土壤和食用林产品中重金属污染与风险评估
Pollution and Risk Assessments of Heavy Metals in Soil and Edible Forest Products from the Typical Mining Area in Shaanxi Prov-ince
摘要
Abstract
To explore the heavy metal pollution characteristics and risk in Shaanxi typical mining soil and edible forest products,through sam-ple collection in Huazhou District Weinan City,Zhashui County,Fengxian County mining area of soil and edible forestry products and analysis of the As,Hg,Pb,Cd,Cr,Cu content,using single factor pollution index method,Nemero comprehensive pollution index method,soil and agricultural products comprehensive quality index method,heavy metal pollution of soil and edible forest products was evaluated.The results showed that the accumulation levels of As,Hg,Pb,Cd,Cr and Cu occurred in the soil in the study area;different degrees of Cr and Cu accu-mulation,two samples of Pb content exceeded the standard;the single pollution index indicated that Cd was the main pollutant in the soil of the study area of Feng County,Cr and Cu were the main soil pollutants in Zhashui County;the soil in Fengxian County and Zhashui sampling area was slightly polluted(quality gradeⅢ),the soil in Huazhou sampling area was still clean state(quality gradeⅡ).The comprehensive quality effect index indicated that,soil in Fengxian County Presents slight pollution(sub-Ⅱ),Huazhou District presents mild pollution(sub-Ⅲ),Zhashui County was heavily polluted(sub-V).Heavy metal pollution occurs in the soil of Fengxian County,Huazhou county and Zhashui re-search area,and remediation measures should be taken in time to reduce the pollution of heavy metals in soil and edible forest products.关键词
