Critical Health Issues Associated with Review of the Scientific Criteria for Oxides of Nitrogen

Abstract

The Clean Air Act (CAA) requires periodic review of existing criteria that form the basis for nitrogen oxides air quality standards. hese air quality criteria are to reflect the latest scientific information useful in indicating the kind and extent of all identifiable effects on public health that may be expected from the presence of nitrogen oxides in ambient air. n keeping with the requirements of the CAA, the U.S. Environmental Protection Agency is reviewing the criteria for nitrogen oxides. uring the initial review, a number of critical issues germane to the review were identified and are presented here. dditional session papers provide more detailed discussion of these issues. his paper discusses specific health issues pertaining to: 1) mechanisms of action of nitrogen oxides; (2) exposure assessment; and (3) specific health effects occurring in groups of individuals considered to be at greatest risk to nitrogen oxides at ambient or near-ambient exposure levels.
