原涉铅企业遗留场地环境状况调查研究

Investigation Research on the Environmental Status of the Leftover Site of the Original Lead-related Enterprise Research

本文以某涉铅企业废弃场地作为研究对象,对厂区内土壤及地下水进行采样分析,测定重金属、有机物等,开展场地环境调查和风险评估工作。厂区内共设8个土壤监测点位和2个地下水监测点位。结果显示,土壤样品所有监测因子含量均低于《土壤环境质量建设用地土壤污染风险管控标准(试行)》(GB 36600—2018)的第二类用地风险筛选值,地下水样品所有监测因子含量均低于《地下水质量标准》(GB/T 14848—2017)的Ⅳ类标准限值。

Taking the abandoned site of a lead-related enterprise as the research object,this paper conducts sampling and analysis of the soil and groundwater in the factory area,determines heavy metals,organic matter,etc.,and conducts site environmental investigation and risk assessment.There are 8 soil monitoring points and 2 groundwater monitoring points in the plant area.The results show that the contents of all monitoring factors in soil samples are lower than the second-type land use risk screening value of the"Soil Environmental Quality Construction Land Soil Pollution Risk Control Standard(Trial)"(GB 36600—2018),and the contents of all monitoring factors in groundwater samples are below the ClassⅣstandard limit of the"Groundwater Quality Standard"(GB/T 14848—2017).
