- Any substance in air which could, if in high enough

material. Pollutants may include almost any natural or artificial
composition of matter capable of being airborne. They may be in
the form of solid particles, liquid droplets, gases, or in
combinations of these forms. Generally, they fall into two main
groups: 1) those emitted directly from identifiable sources and
2) those produced in the air by interaction between two or more
primary pollutants, or by reaction with normal atmospheric
constituents, with or without photoactivation. Exclusive of
pollen, fog, and dust, which are of natural origin, about 100
contaminants have been identified and fall into the following
categories: solids, sulfur compounds, volatile organic chemicals,
nitrogen compounds, oxygen compounds, halogen compounds,
radioactive compounds, and odors.
