摘要
为研究安徽某河道清淤底泥填埋场清运整平后场地污染现状,对原填埋区30个土壤样品8种重金属指标进行检测分析,采用现行土壤质量标准、单因子指数及潜在生态风险指数等方法进行环境风险评价,为污染场地治理及利用提供科学依据。分析表明:原淤泥填埋场地处于中度污染状态,但土壤中Cu、Zn、Pb、Cd、Cr、Hg、Ni、As检测浓度符合GB 36600—2018《建设用地土壤污染风险管控标准(试行)》第二类用地风险筛选值及CJ/T 340—2016《绿化种植土壤》Ⅱ级标准;污染因子Hg是导致环境风险等级提级的主要因素。
In order to investigate the current situation of site pollution after the clearing and trans-portation of a river sludge landfill in Anhui Province 30 soil samples and 8 kinds of heavy metal indicators in the original landfill area are monitored and analyzed and the current soil city quality standards single-factor index and potential ecological risk index and other methods were used to e-valuate environmental risks.It provides a scienti-fic basis for the contaminated site governance and utilization.The analysis shows that the original sludge landfill site is in a moderate state of pollu-tion but the concentration of Cu Zn Pb Cd Cr Hg Ni and As in the soil meets the second type of land risk screening value of GB 36600—2018 Construction Land Soil Pollution Risk Control Standards Trial Implementation and the CJ/T 340—2016 Green Planting Soil Level II standard The pollution factor Hg is the main factors leading to the upgrade of the envinonmental risk level.
