黄石市某地区土壤重金属污染状况研究

Research on Soil Heavy Metal Pollution in a Certain Area of Huangshi City

该文以湖北省黄石市某地区土壤为研究对象,选取Cu、Pb、Cr、Cd、As 5种元素作为评价要素,对土壤中重金属含量和污染状况进行了测定和分析。结果表明:研究区域土壤重金属含量较高,Cu、Pb、Cd、As超过了湖北省土壤背景值。单因子污染指数法评价Cu、Pb、Cd、As重金属污染较为突出;潜在生态危害系数法评价厂区周边土壤潜在危害性大;内梅罗综合污染指数法评价污染严重。

In order to study the soil heavy metal pollution in a certain area of Huangshi City,Hubei Province,this article takes soil as the research object and selects five elements:Cu,Pb,Cr,Cd,and As as evaluation elements.The morphological distribution and pollution of heavy metals in the soil were analyzed and determined in detail.The results showed that the content of heavy metals in the soil in the study area was high,and Cu,Pb,Cd,As heavy metal exceeded the National soil environmental quality standards.The single factor pollution index method to evaluate Cu,Pb,Cd,As heavy metal pollution is more prominent;The evaluation of potential ecological hazard coefficient method shows heavy pollution at all points;Neimero comprehensive pollution index method to evaluate those heavy metal pollution is serious pollution.
