Air Pollutants of Concern

There are thousands of different air pollutants, defined as any gas or particle found in concentrations in excess of what is of natural origin. While some are relatively benign, others may be found in concentrations high enough to cause health or environmental impacts. Almost any gas or particle in high enough concentrations will cause some type of health response. Generally, air pollutants of most concern can be broken into three categories: the criteria pollutants, regulated toxic air pollutants (or hazardous air pollutants), and greenhouse gases. more...
