摘要
本文以佛山市土壤污染重点监管单位、典型行业企业用地土壤为研究对象,对24家企业共计358个样本中重金属As、Cd、Cu、Pb、Hg、Ni、Cr、Zn的含量进行统计分析。采用内梅罗综合指数法、污染负荷指数法对土壤重金属元素污染状况进行评价。结果表明:8种重金属的平均含量均超过了广东省土壤背景值,且有少量样本中的As、Pb超过筛选值。内梅罗综合污染指数法评价结果表明,原油加工及制造业土壤为轻度重金属污染,纺织及印染加工、电池制造业的土壤重金属呈现重度污染,其他类型工业用地土壤重金属为安全或接近警戒状态。污染负荷指数法评价结果表明,7个不同类型工业用地的土壤均受到不同程度的重金属污染。
Taking the soil used by key regulatory units and typical industry enterprises in Foshan City as the research object,the content of heavy metals As,Cd,Cu,Pb,Hg,Ni,Cr,and Zn in a total of 358 samples from 24 enterprises was statistically analyzed.The soil heavy metal pollution status was evaluated using the Nemero comprehensive index method and pollution burden index method.The results showed that the average content of 8 heavy metals exceeded the soil background value in Guangdong Province,and a small number of samples had As and Pb exceeding the screening values.The evaluation results of the Nemero comprehensive pollution index method show that the soil of crude oil processing and manufacturing industries is lightly polluted by heavy metals,while the soil of textile,printing and dyeing processing,and battery manufacturing industries is heavily polluted by heavy metals.Other types of industrial land soil heavy metals are in a safe or near alert state.The evaluation results of the pollution load index method indicate that the soils of seven different types of industrial land are all contaminated with varying degrees of heavy metals.
