重点危化品环境风险评估与突发环境事件风险评估应用分析

Analysis on the Application of Environmental Risk Assessment of Key Hazardous Chemicals

通过对环境保护部出台的《重点环境管理危险化学品环境风险评估报告编制指南(试行)》和《企业突发环境事件风险评估指南(试行)》中两种环境风险等级评估方法原理、评估程序、评估重点、指标设置、分级原则的比较,并结合案例,进一步分析了两套评估方法对企业日常环境风险分级管理的作用。经比较分析后,两套评估方法在石油石化行业应用时,方法原理和评估目的一致,但因指标侧重不同,导致评估结果有一定的差异,突发环境事件风险评估工作量大,却难以实现石油石化企业环境风险分级管理的目的,危化品环境风险评估过程更具指导性,但危化品名录的局限导致评估不能覆盖突发环境风险的物质,据此提出了两套方法融合后开展日常环境风险评估的建议。

Through the comparisons of principle,evaluation procedure,key points,indicator setting and classification principle,and combining with the case,this paper analyzes two evaluation methods which were issued by Ministry of Environmental Protection for the daily environmental risk classification management of enterprise.The principles and evaluation purposes of the two evaluation methods show no differences,however,the two methods pay particular emphasis on index so that the evaluation results have certain differences.The workload of environmental risk assessment is difficult to realize the purpose of the environmental risk classification management of petrochemical enterprises,but the process of environmental risk assessment of hazardous chemicals is more instructive.Since the limitations of the hazardous chemicals list will result in the assessment that cannot be covered by environmental risks substance,it is suggested that the daily environmental risk assessment is carried out with the combination of the two methods.
