EPA May Go Beyond Law and Science in Setting NAAQS

Information from highly respected sources, such as the American Cancer Society, indicates that only about 2 percent of cancer deaths in the United States are the result of exposures to carcinogenic agents in the workplace, community, and other settings. But the news about health risks from environmental exposures to air pollutants is almost constant. Although the US air quality has improved dramatically in the last 30 years, each recent review of a National Ambient Air Quality Standard (NAAQS) by the US Environmental Protection Agency (EPA) has resulted in a reduction in existing standards or replacement by a completely different and generally more stringent standard.
