Assuring Public Health Protection as a Result of the Mobile Source Emissions Control Program

Provisions of the Clean Air Act Amendments are explained in this paper. Carbon monoxide, hydrocarbons, and oxides of nitrogen are specifically regulated emissions; fuels, fuel additives, and lubricants can be regulated, and a host of nonregulated emissions can be regulated on need.

In examining these three categories of pollutants, the paper describes the health consequences of regulated and nonregulated emissions, the effects of various components on nonregulated emissions, and the effect of advanced control systems on regulated and nonregulated emissions. Finally, current EPA research on fuel and fuel additive registration, emissions characterization, health, and surveillance is discussed.
