Cleaning Up Commonly Found Air Pollutants
The six common air pollutants of primary concern to the United States are particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. These pollutants are detrimental to health, the environment, and a person's home and other belongings. The worst two of the six pollutants are particle pollution and ground-level ozone, which have to be regulated by the EPA. Particle pollution, or particle matter, consists of soot, smoke, and chemically formed "droplets". These particles are very small and can bury themselves deep inside the lungs. Ground-level ozone is found in smog and can also negatively affect the lungs. Ozone is composed of two chemicals called volatile organic compounds (VOCs) and nitrogen oxides (NOx). VOCs come from cars burning gasoline, petroleum refineries, chemical manufacturing plants, etc., while NOx results from burning gasoline, coal, or oil.

Famous quotes containing the words cleaning, commonly and/or air:
“The disgust with dirt can be so great that it keeps us from cleaning ourselves—from “justifying” ourselves.”
—Friedrich Nietzsche (1844–1900)
“They commonly celebrate those beaches only which have a hotel on them, not those which have a humane house alone. But I wished to see that seashore where man’s works are wrecks; to put up at the true Atlantic House, where the ocean is land-lord as well as sea-lord, and comes ashore without a wharf for the landing; where the crumbling land is the only invalid, or at best is but dry land, and that is all you can say of it.”
—Henry David Thoreau (1817–1862)
“The thundering line of battle stands,
And in the air Death moans and sings:
But Day shall clasp him with strong hands,
And Night shall fold him in soft wings.”
—Julian Grenfell (1888–1915)
