How does EPA evaluate air quality?

EPA uses six "criteria pollutants" as indicators of air quality: ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, particulate matter and lead.  For each of these, EPA has established "primary" standards to protect public health, and "secondary" standards to protect other aspects of public welfare, such as preventing materials damage, preventing crop and vegetation damage, or assuring visibility.  These standards are called the National Ambient Air Quality Standards (NAAQS).  In addition, EPA has issued an Air Quality Index which gives citizens critical Information to take necessary health precautions.
