Sulfur Dioxide (So2) - ✔✔___________: This is a colorless, corrosive gas
that damages both plants and animals.
Ambient Air - ✔✔This is the air around us.

, pollutants: sulfur dioxide, nitrogen oxides, carbon monoxide, ozone (and
its precursor volatile organic compounds), lead, and particulate matter.
These six are referred to as _____________.
Carbon Monoxide (CO) - ✔✔___________: This is less common but more
dangerous than the principal form of atmospheric carbon, carbon dioxide
(CO2).
Photochemical Oxidants - ✔✔___________: These are compounds created
by reactions driven by solar energy and atmospheric acids are probably the
most important secondary pollutants.
Aerosols - ✔✔___________: These are extremely minute particles or liquid
droplets suspended in the air, are included in this class.
Particulate Material - ✔✔___________: This includes dust, ash, soot, lint,
smoke, pollen, spores, algal cells, and many other suspended materials.
