National air quality and emissions trends report, 1996
Technical Report
·
OSTI ID:620586
This document is the twenty-fourth annual report documenting air pollution trends in the United States. While in recent years this report has widened its scope to include air pollution topics such as acid rain, visibility, and air toxics, its focus remains on those pollutants for which the United States Environmental Protection Agency (EPA) has established National Ambient Air Quality Standards (NAAQS). Primary standards are designed to protect public health, including sensitive populations such as children and the elderly, while secondary standards protect public welfare, such as the effects of air pollution on vegetation, materials, and visibility. There are six criteria pollutants with primary standards: carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), and sulfur dioxide (SO2).
