Environmental Transport Modeling of Pollutants in Water and Soil.

摘要

A suite of models is discussed which can be applied to calculation of first order effects in transport of several types of pollutants in water and soil. The materials considered include solids in the form of particulates and soluble forms of the heavy metals. The time scale that is currently being emphasized is discussed, along with the physical size of the area covered by these calculations. The role of the hydrologic cycle is introduced along with the importance of bulk flow and particulate transport as suspended sediment. The build-up of lead, cadmium, zinc, and copper in the soil near a lead smelter over a six-year period is presented. (ERA citation 01:021023)
