| 摘 要： | 以某有机污染场地为例，对比分析了 ＲBCA 和 CLEA 模型评价原理和方法，并通过毒理学方法分析了评价结果与污染场地实际情况的符合程度。研究表明，两种模型在评价方法、适用范围方面存在差异，ＲBCA 模型适合需要综合考虑污染物在水、土、气中迁移转化的污染场地健康风险评价; CLEA 模型适合以摄入污染场地种植植物为主要暴露途径的健康风险评价。

| Abstract: | Taking an organic- contaminated site as example， the authors compares ＲBCA and CLEA models on their assessment theories and methods． Furthermore，the degree of conformity between the evaluation results and the actual situation of the pollution has been analyzed through the toxicology methods． The results indicate that two models are different in assessment method and application scope． ＲBCA model is superior on comprehensive assess- ment of the migration and transform of pollutants in water，soil and gas，while CLEA model is capable for the as- sessment of contaminated sites where the main exposure pathway comes from ingestion of contaminated vegetation etc． |
