摘　　要：建设用地土壤污染筛选值和管制值可用于土壤污染风险管控和修复决策。基于国内外建设用地土壤污染健康风险评估的基础理论和方法学,通过多介质暴露评估模型筛选、本土化模型参数确定、模型理论值计算、理论值修正定值等过程,针对深圳市建设用地土地利用特征和典型行业企业污染物类型,研究制定了第一类和第二类用地情形下68项污染物的土壤污染风险筛选值和管制值,分析了主要国家和地区建设用地的分类差异。研究表明:不同污染物的第二类用地筛选值均高于第一类用地,同一种污染物的管制值高于筛选值,制定的筛选值和管制值处于具有代表性的国内外同类土壤污染风险管控标准限值范围内,暴露评估模型选择、受体暴露、土壤性质、空气特征、污染物毒性等参数取值及模型理论计算值修正是国内外筛选值存在差异的主要原因。研究结果对深圳市建设用地土壤污染风险筛查和风险管制具有重要指导作用。The risk screening and intervention values for soil contamination of development land can be used for decisionmaking on soil pollution risk control and remediation.This study was based on the basic theory and methodology of soil pollution health risk assessment for global development land.It involved selecting multi-medium exposure assessment models,determining localized model parameters,calculating model theoretical values,and correcting model theoretical values.Based on the characteristics of land use for development land and the types of pollutants in typical industries in Shenzhen,the soil risk screening and intervention values for 68 pollutants under the first and second types of land use were established.The classification differences of development land in major countries and regions were analyzed.The study showed that the secondcategory land screening value of pollutants was higher than the first-category land,and the intervention value of the same pollutant was higher than the screening value.The screening and intervention values were within the representative range of similar soil pollution risk control standards at home and overseas.The main reasons for the differences in screening values at home and overseas are the selection of exposure assessment models,receptor exposure values,soil properties,air characteristics,pollutant toxicity parameters,and the correction of theoretical calculation values for the model.The results will play a guiding role in risk screening and control for soil contamination of development land in Shenzhen.
