摘要
通过对化工厂污染土壤多环芳烃的监测及统计分析,结合现场实际分析了污染来源,揭示了多环芳烃的污染现状及其环境风险。结果表明:研究区域存在严重的多环芳烃污染,土壤污染最高超标250倍。统计分析表明:土壤多环芳烃元素之间存在着不同程度的相关。内梅罗综合指数评价结果表明采样区域土壤存在严重有机污染,其中工业污染是最主要的污染源。
The PAHs pollution and statistical analysis in soil of chemical plant were investigated.The pollution sources and potential environmental risk are revealed on the basis of real facts.The results indicate that the target areas in the chemical plant are polluted seriously by PAHs.The maximum value of soil pollution can reach more than 250 times than that of the national standard.The elements of the PAHs are high related each other.There is serious soil pollution with organic pollutants,and one of the main pollution sources is industrial pollution by assessment of Nemerow index method.
