Pollutant metals released to the environment disperse and interact in various ways before arriving at sensitive receptors. Modeling of pollutant behavior may be by time-dependent or time-independent means. The time-independent, exposure commitment method requires a less extensive data base and can begin with general associations between environmental concentrations or fluxes. Such assessments for representative background conditions have been performed for most of the metals associated with acid precipitation. Examples are given here for cadmium and mercury. These overviews are only the beginning stage of relating pollutant releases to environmental effects.
释放到环境中的污染金属在到达敏感受体之前会以各种方式扩散和相互作用。污染物行为的建模可以通过时间相关或时间无关的方法进行。时间无关的暴露承诺方法需要的数据基础较不广泛，可以从环境浓度或通量之间的一般关联开始。对于与酸沉降相关的大多数金属，已经针对代表性背景条件进行了此类评估。这里给出了镉和汞的例子。这些概述仅仅是将污染物排放与环境影响联系起来的起始阶段。
