基于建筑物结构的污染场地健康风险评估模型优化及分析
Optimization and Analysis of Health Risk Assessment Model for Contaminated Sites Based on Building Structures
摘要
Abstract
Combined with the actual situation of volatile organic compounds(VOCs)pollution remediation,and considering the influence of building structures on risks,the assessment models for two scenarios were established:direct contact between contaminated soil areas and building floor slabs(A1)and direct contact between contaminated groundwater areas and building floor slabs(B1),and the corresponding risk assessment formulas were proposed.Combined with practical cases,the assessment results obtained from the evaluation model recommended in the HJ 25.3-2019 Technical Guidelines for Risk Assessment of Contaminated Construction Land and the optimized model were analyzed and compared.Under Scenario A1,the risk values of deep soil contamination calculated by the guideline-recommended model were overestimated,while those for topsoil and subsoil were underestimated.This indicated that the guideline model could overrate the pollution risks of deep soil contamination as well as the required remediation workload of contaminated sites.Under Scenario B1,the carcinogenic risks calculated by the guideline model was far lower than that of the optimized model,which suggested that the guideline model may underestimate carcinogenic risks when contaminated groundwater submerged the basements.关键词
