摘　　要：3MRA(the Multimedia, Multi–pathway, Multi-receptor Exposure and Risk Assessment)是第一代模型,是一种在不确定条件下,针对全国性多介质、多途径和多受体进行风险评估的体系,用于评估废物处置区域内对生态、人类构成风险的污染物的浓度阈值。本文中,通过对3MRA模型及其在国内外发展应用现状的综述,认为模型具有良好的应用发展前景,并从4个方面提出借鉴使用模型的建议方法,为我国废物管理提供决策依据。A first-generation model—the Multimedia, Multi-pathway, Multi-receptor Exposure and Risk Assessment (3MRA) is a flexible framework for conducting nationwide multimedia, multi-pathway and multi-receptor risk assessments under uncertainty, which is developed to estimate protective chemical concentration limits in a source area. In this paper, according to the summary of the 3MRA model and its development and application at home and abroad, it is affirmed that 3MRA model has a good prospect of application. Finally, the methods of referencing and using model are proposed from four aspects, providing decision-making basis for waste management in our country.
