Carbon Monoxide NAAQS Review - Analyses and Data Sets
The Clean Air Act requires EPA to set national air quality standards for carbon monoxide and five other pollutants considered harmful to public health and the environment (the other pollutants are lead, nitrogen oxides, ozone, particulate matter and sulfur dioxide). The law also requires EPA to periodically review the standards to ensure that they provide adequate health and environmental protection, and to update those standards as necessary.
