Abstract

An integrated spatial-multimedia-compartmental model (ISMCM) of chemical transport and fate was developed to predict environmental partitioning of both volatile and semi-volatile organics. The model is composed of eight compartments namely, air-gaseous phase, air-particulate phase, water, suspended solids (in water), biota (in water), sediment, soil, and vegetation. These compartments are described by a series of ordinary and partial differential equations which are solved simultaneously subject to the appropriate physical boundary conditions. The ISMCM provides a detailed description of intermedia transport processes associated with the gaseous, dissolved, and particle phases. For example, detailed modules are included to describe the rain scavenging of gaseous and particle-bound chemicals, dry deposition, wind erosi
