Criteria Air Pollutants

The Clean Air Act (1970) set air quality standards for six pollutants, known as "criteria air pollutants". Learn more about criteria air pollutatnts from the EPA. They are important. Have a sense of their general sources and health effects.

Particulate Matter (PM)

Described in microns: PM10 (coarse), PM2.5 (fine), and PM 1 (ultrafine). The smaller it is, the deeper it can lodge in your lungs -- and enter your bloodstream. Think cardiovascular problems.

Learn more about particulate matter from the EPA


Ozone (O3)

Ozone is simply three oxygen molecules bound together.

"Good up high, bad nearby"

In the stratosphere, it protects us from radiation, though next to the surface (ground-level or tropospheric), it can produce airway inflammation.

Learn more about ground-level ozone from EPA

Nitrogen Oxides (NOx)

Atmospheric pollutants often found from fossil fuel combustion (e.g., car exhaust, coal-burning factories, and many other sources.


Learn more about:

Sulfur Dioxide (SO2)

Burning of fossil fuels (and volcano emissions!) produce sulfur dioxides that can irritate airways, especially problematic for people with asthma.

Learn more about sulfur dioxide from EPA or via the CDC

Carbon Monoxide (CO)

From combustion of fossil fuels and a burn byproduct in general (e.g., wildfires). Binds to hemoglobin more efficiently, so your brain and body get starved of oxygen. Known as the "quiet killer" or "invisible killer".

Learn more about carbon monoxide from EPA


Lead

Once in the body, it can cause a lot of problems, like cognitive function impairments. Especially harmful for kids who are still developing.
