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:
“Conventionalities are at length as bad as impurities. Even the facts of science may dust the mind by their dryness, unless they are in a sense effaced each morning, or rather rendered fertile by the dews of fresh and living truth.”
—Henry David Thoreau (1817–1862)
“The way a crow
Shook down on me
The dust of snow
From a hemlock tree.”
—Robert Frost (1874–1963)
“‘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;”
—Percy Bysshe Shelley (1792–1822)
