Integrated Science Assessment for Oxides of Nitrogen-Health
Criteria, the agency's latest evaluation of the scientific literature

The EPA on Monday released the final Integrated Science Assessment for Oxides of Nitrogen-Health Criteria, the agency's latest evaluation of the scientific literature on the potential adverse human health effects resulting from exposures to oxides of nitrogen, particularly NO2. According to an agency release, there are significant new health data, particularly epidemiological studies, since the last scientific review document released in 1993.
Oxides of nitrogen is one of the six criteria pollutants for which the EPA is required to issue air quality criteria under the Clean Air Act. The agency set a national ambient air quality standard for NO2, an indicator for gaseous nitrogen oxides, at an annual average of 0.053 ppm.
The act also requires the agency to periodically update the scientific basis for these standards by preparing an integrated science assessment. The assessment, the EPA said, will be critical in the review of the NAAQS for NO2. The document went through independent, external peer review by the Clean Air Scientific Advisory Committee, and opportunities were also provided for public review and comment.
