The report presents estimates of trends in nationwide air pollutant emissions for six major pollutants: particulate (PM/TSP and PM10), sulfur oxides, nitrogen oxides, reactive volatile organic compounds, carbon monoxide, and lead. Estimates are provided for major categories of air pollution sources. A short analysis of emission trends is given along with a discussion of methods used to develop the data.
