What are the criteria for air pollutants?
EPA has established national ambient air quality standards (NAAQS) for six of the most common air pollutants— carbon monoxide, lead, ground-level ozone, particulate matter, nitrogen dioxide, and sulfur dioxide—known as “criteria” air pollutants (or simply “criteria pollutants”).
What are the 6 regulated pollutants by the Clean Air Act?
Six Criteria Air Pollutants: Carbon Monoxide, Ground-level Ozone, Lead, Nitrogen Oxides, Particulate Matter, and Sulfur Dioxide. The Clean Air Act (CAA) requires EPA to set National Ambient Air Quality Standards (NAAQS) for six common air pollutants.
What is not a criteria pollutant?
All pollutants not classified as criteria air pollutants can be said to be non-criteria pollutants. Non-criteria pollutants include benzene, dioxins and pesticides.
What are the types of criteria pollutants?

What are criteria and non-criteria pollutants?
What Does Non-Criteria Pollutants Mean? Six criteria air pollutants are covered by NAAQS, a further list of 189 pollutants are listed as Hazardous Air Pollutants (HAPs) in the Clean Air Act. Non-criteria pollutants include benzene, dioxins and pesticides.
Are VOCs criteria pollutants?
VOCs are an important pollutant because of their contribution to the formation of ground-level ozone. When VOCs are released into the atmosphere, they react with nitrogen oxides (NOx) to create ozone molecules.
What is meant by criteria pollutants?
Criteria Air Pollutants means an air pollutant for which acceptable levels of exposure can be determined and for which an ambient air quality standard has been set. Examples include: ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and PM10 and PM2.
Which of these is not a criteria pollutant?
