工业污染场地规划为高架建设用地人体健康风险评估

Human Health Risk Assessment of an Industrial contaminated Site Planned for Use as Overhead Construction Land

以某化工厂搬迁遗留场地为例,结合《污染场地风险评估技术导则》(HJ 25.3-2014),对污染场地用作高架桥建设进行了人体健康风险评估。并建议该场地进行原位修复,根据暴露途径的差异对上层土壤、下层土壤、微承压地下水分别设置了风险控制值。

With the left field of a relocated chemical plant as an example, combining ＂HJ 25.3-2014＂, a human health risk assessment was made on using the contaminated sites for construction of a viaduct. It is recommended that the site should be repaired in situ, and based on the differences of the exposure pathways, the risk control values were set for the upper soil, subsoil and micro confined groundwater respectively.
