| 为深入研究和探讨废弃化工场地的有机污染现状和环境风险问题，本文选择河北邯郸某化工场地，开展场地及周边区域的污染判别和分析，确定重点关注区、次重点关注区和一般关注区，进行针对性的不同深度土壤样品采集，分析土壤中重金属、挥发性有机化合物（VOCs）、半挥发性有机化合物（SVOCs）和总石油烃类等污染物质的含量，综合研究土壤污染的现状情况和空间分布特征，运用污染物苯、人体接触污染介质、污染物苯的迁移途径、污染物的接触方式等要素的污染评估模型，经污染物暴露计算模型、污染物毒性评估模型、风险计算模型进行综合建模研究，确定挥发性有机物（VOCs）苯存在较大的致癌环境风险，研究苯污染物环境传输模型和迁移规律。该研究为污染场地环境风险研究提供技术研究思路，也为污染场地开展风险评估、土壤治理和土地利用规划提供基础依据，实现污染土地的环境安全再利用。 |

| In order to study and explore the current status of organic pollution and environmental risks in abandoned chemical sites， a chemical site in Handan， Hebei was selected. Based on pollution discrimination and analysis of the site and surrounding areas， key concerned areas， sub-key concerned areas， and general concerned areas were identified. Based on the above research， targeted soil samples were collected at different depths to analyze the content of heavy metals， volatile organic compounds （VOCs）， semi volatile organic compounds （SVOCs）， and total petroleum hydrocarbons in the soil， in order to study the current situation and spatial distribution characteristics of soil pollution comprehensively. Then， a pollution assessment model is applied， including factors such as benzene， human exposure to pollution media， migration pathways of benzene， and contact patterns of pollutants. According to comprehensive modeling research through pollutant exposure calculation models， pollutant toxicity assessment models， and risk calculation models， it is determined that volatile organic compounds （VOCs） benzene has a significant carcinogenic environmental risk， as well as environmental transport models and migration patterns of benzene pollutants. This study provides technical research ideas for the study of environmental risks of contaminated sites， and also a basic basis for risk assessment， soil management， and land use planning of contaminated sites， achieving the safe reuse of polluted land in the environment. |
