摘要多媒体环境污染物评估系统（MEPAS）是一个基于物理的风险计算代码，它集成了源项、迁移和暴露模型。由太平洋西北实验室（a）为筛选环境问题和对环境问题进行排序而开发的MEPAS，旨在利用现有信息对特定地点进行评估，以估计潜在的健康影响。计算化学和放射性致癌物的风险值，而危险因子，根据参考剂量，计算非致癌物。该系统具有广泛的适用性，以一系列的环境问题，使用空气，地下水，地表水，陆上，和曝光模型。在适当的情况下，美国环境保护署的指导和模型被用来促进兼容性和接受。虽然基于相对标准的运输和暴露计算方法，但MEPAS的独特之处在于，这些方法被整合到一个单一的系统中。使用…
ABSTRACT The Multimedia Environmental Pollutant Assessment System (MEPAS) is a physics-based risk computation code that integrates source-term, transport, and exposure models. Developed by Pacific Northwest Laboratory(a) for screening and ranking of environmental problems, MEPAS is designed for site-specific assessments using readily available information to estimate potential health impacts. Risk values are computed for chemical and radioactive carcinogens; while hazard quotients, based on reference doses, are computed for noncarcinogens. This system has wide applicability to a range of environmental problems using air, groundwater, surface-water, overland, and exposure models. Whenever available and appropriate, U.S. Environmental Protection Agency guidance and models were used to facilitate compatibility and acceptance. Although based on relatively standard transport and exposure computation approaches, the unique feature of MEPAS is that these approaches are integrated into a single system. The use of...
