Pollution Sources and Criteria Pollutants

A lot of air pollution is invisible. In this case, what we can't see does hurt us!

What are criteria pollutants? Scientists have established specific levels of each of 6 common air pollutants which are dangerous to our health and welfare.
Levels of these criteria pollutants are monitored and strictly regulated
In order to protect us, levels of these criteria pollutants are monitored and strictly regulated. 4 of the 6 are directly produced by burning! Burning either fossil fuels (coal, oil or natural gas) or wood causes air pollution which has devastating effects on our lungs and our environment.

What are they, where do they come from, and what do they do to us and our environment? Click on a molecule to the left to see the criteria pollutants at a glance!
