Which pollutant is NOT included in the National Ambient Air Quality Standards (NAAQS)?

Explanation:
NAAQS sets ambient air quality standards for six criteria pollutants to protect public health and welfare. Those pollutants include carbon monoxide, lead, nitrogen dioxide, ozone, sulfur dioxide, and particulate matter. Asbestos, while a hazardous air pollutant, is not one of the criteria pollutants covered by NAAQS and is regulated under separate hazardous air pollutant rules. So the pollutant not included in the NAAQS is asbestos.
