The deposition of sulfate and nitrate species by dry and wet removal processes has become a topic of increasing concern in recent years because of the possible ecological effects of the acidity associated with these species on soil and watersheds. Although there is little controversy about the need for reducing acid deposition, the strategies that have been proposed to address the problem differ widely. One of the principal questions that arises in connection with the acid deposition problem is the effect of controlling primary pollutants on the levels of sulfate and nitrate deposition. Mathematical modeling of the physical and chemical atmospheric processes involved in the formation, transport, and deposition of sulfate and nitrate species can provide useful information in addressing this problem. In this paper, we present a mathematical model that provides a detailed treatment of both gas-phase and liquid-phase acid rain chemistry. The model is applied to a hypothetical case study characteristic of the northeastern United States. Section 2 presents the description of the model. The results of the model applications are presented and discussed in Section 3. Conclusions are presented in Section 4.
