NMAM (National Ambient Air Quality Standards)

The National Ambient Air Quality Standards (NAAQS) are limits set by the U.S. government to ensure clean air for everyone. These standards specify the acceptable levels of common pollutants—like ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead—in the outdoor air. The goal is to protect public health and the environment by keeping air pollution below levels that could cause health issues or environmental damage. Monitoring these pollutants helps identify areas with poor air quality, guiding actions to reduce pollution and improve air safety for communities.
