摘要

摘要: 污染场地风险评估是污染土地再开发过程中的重要环节。由于污染物的属性及来源不同，污染物在土壤中的残留具有明显的分层特点。以某复合型化工污染场地土壤修复为例，采用美国GSI公司开发的RBCA模型，对该污染场地进行分地层健康风险评估，取得了主要污染物在不同地层中的风险状况。结果表明，该污染场地即存在致癌风险也存在非致癌风险，但以有机致癌风险为主。根据该风险评估结果，能为后续的污染场地修复制定有针对性的修复方案，增强修复效果，节约修复费用。

Abstract: Risk assessment is an important issue in redevelopment of contaminated land. Due to the different attributes and sources, there are obvious layered characteristics for residual pollutants in soil. With a compound chemical contaminated site soil remediation as an example, the health risk assessment for multi-layer soil was carried out by RBCA model from the American GSI company. The risk status for the main pollutants in different layer of soil was obtained. The results showed that there were both carcinogenic and non-cancer risks in the contaminated site, but mainly with organic carcinogenic risk. According to the results of the risk assessment, the subsequent projects of remediation for the contaminated site can be established, enhancing the remediation effect and saving the cost of remediation.
