多种媒介环境模型的逸度方法

Fugacity Approach in Multimedia Environmental Modeling

详细评述一种越来越广泛地得到公认的环境模型———逸度方法．这种模型利用了逸度之概念，已被成功地用于描述化学物质在全球、地区及局部环境（包括湖泊、河流、污水处理厂，植物和土壤等）中的行为．该方法的优点是模型中数学表达式更容易编制和运作．计算方法可推广到任意数目的环境媒介，而且模型也有助于对环境监测数据的解释．

Assessment of the environmental fates of chemicals can be facilitated by the application of mathematical models which describe the partitioning, transport and transformation processes of the chemicals in the environment. One modeling approach which is getting wider and wider acceptance is the fugacity approach, which is discussed in this review article. This modeling approach employs the concept of fugacity and has been successfully used to describe the behavior of chemicals in the global, regional and local environment, including lakes, rivers, sewage treatment plants, facilities, and soils. The advantages of this approach are that the algebraic expressions are more easily compiled and manipulated, the calculations can be extended to any number of environmental media and the modeling can be used in assisting interpretation of environmental monitoring data.
