Continue air pollution notes...

There are 6 types of air pollution recognized and monitored by the US Environmental Protection Agency

The Clean Air Act requires EPA to set National Ambient Air Quality Standards (NAAQS) for these air pollutants (aks "criteria air pollutants"). These pollutants are found all over the U.S.:

PM - particulate matter
CO - carbon monoxide
O3 - ozone (ground level pollution)
SO2 - sulfur dioxide
NOx - nitrogen oxides
Pb - lead

These all occur in the troposphere, from 0-12km  


Create a chart in notebook and we will fill in with causes, concerns, solutions together for each of these 6 pollutants:
