Dust
Dust consists of particles in the atmosphere that come from various sources such as soil dust lifted by weather (an Aeolian process), volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles and many other materials which may be found in the local environment.

Famous quotes containing the word dust:
“Truth has not single victories; all things are its organs,—not only dust and stones, but errors and lies.”
—Ralph Waldo Emerson (1803–1882)

—Henry David Thoreau (1817–1862)
“‘All that was, seemed as if it had been not;
And all the gazer’s mind was strewn beneath
Her feet like embers; and she, thought by thought,
‘Trampled its sparks into the dust of death;”
