Matrix of air pollutants in Massachusetts, their sources and health effects.

Overview of the role municipal waste combustors play in our state's waste management system, how they operate and are regulated, and the progress they are making toward reducing their emissions of targeted air pollutants.

Emission inventories are available for designated areas failing to meet the National Ambient Air Quality Standards (NAAQS) for Ozone and Carbon Monoxide (CO) .

Plans for pollution control measures at power plants to help meet the pollutant emission limitations.

Motor vehicles, engines, and fuels are among the leading contributors to air pollution in Massachusetts. Each of us can make a difference in the quality of the air we breathe by driving clean-running and fuel-efficient vehicles, keeping them well maintained, and making smart commuting choices.

Motor vehicles on the road account for about 40 percent of the pollutants - hydrocarbons and nitrogen oxides - that react with sunlight on hot days to produce ground-level ozone, the main ingredient in smog.
