摘要：以某搬迁或撤离的金属加工厂为例，对其遗留的地块进行场地环境调查及其人群健康风险评估。结合调查评估的土壤及地下水检测数据，最终确定重金属镉和锑为本场地关注污染物。根据健康风险评估模型，结果发现锑和镉的非致癌风险超出人体正常风险水平。通过计算，关注污染物锑的风险控制值为5.7mg/kg，镉的风险控制值为11.9mg/kg，进而得出本场地目标修复值，为后续场地环境修复做出理论基础。

Abstract：Site environmental survey and health risk assessment has been carried out a former relocation site of metal processing.According to soil and groundwater testing data，cadmium and antimony were considered as the concerning contaminant.According to health risk assessment model，it was found that the non-carcinogenic risk of cadmium and antimony were higher than the normal acceptable level of human body.Basing on model calculation formula，the value risk control of antimony was 5.7mg/kg，the value risk control of cadmium was 11.9mg/kg.Besides，target repair value was determined so that it was to lay the groundwork for the environmental repair theory.

随着我国城市化进程和产业转移步伐的加快，经济发达或快速发展地区的工业企业搬迁呈現普遍的趋势[1]。与此同时，搬迁企业的关停与撤离导致大量污染土地遗留下来，涉及土壤及地下水污染、原有企业危险废物及一般废物丢弃引起的污染等，这些突出问题已经成为目前城市工业变革的产物[2-3]。

在污染场地再开发的过程中，由于安全防护或前期准备工作的不足，遗留的有毒有害物质泄漏引起人体及环境的不良反应，高传染性和高风险性成为了此类地块的一个显著特点[4]。这些高污染特性使周边居民长期生活及暴露在危险环境中，严重危害居民身心健康。因此，对已搬迁或关停企业的土壤污染防控及风险管理刻不容缓。
