Abstract | The Clean Air Act (CAA) requires periodic review of existing criteria that form the basis for carbon monoxide (CO) air quality standards. These 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 CO in ambient air. In keeping with the requirements of the CAA, the U.S. Environmental Protection Agency has started to review the criteria for CO. A number of critical issues germane to the review are presented. Additional session papers provide more detailed discussion of these issues. The paper discusses specific health issues pertaining to: (1) mechanisms of action of CO, particularly an evaluation of intracellular mechanisms secondary to impaired oxygen delivery caused by the formation of carboxyhemoglobin (COHb); (2) exposure assessment, including an evaluation of the accuracy and reliability of different methods for determining COHb; and (3) specific health effects occurring in groups of individuals considered to be at greatest risk to CO at ambient or near-ambient exposure levels including a reevaluation of previous dose-response functions for CO utilizing the information gained from recently completed studies. These critical issues will need to be resolved in order to determine the extent to which adverse effects are occurring in the population, particularly at the lower COHb levels of greatest interest to standard setting. |
