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:
“These, and such as these, must be our antiquities, for lack of human vestiges. The monuments of heroes and the temples of the gods which may once have stood on the banks of this river are now, at any rate, returned to dust and primitive soil. The murmur of unchronicled nations has died away along these shores, and once more Lowell and Manchester are on the trail of the Indian.”
—Henry David Thoreau (1817–1862)
“Be it so, for I submit; his doom is fair,
That dust I am and shall to dust return.
O welcome hour whenever! Why delays
His hand to execute what his decree
Fixed on this day? Why do I overlive?
Why am I mocked with death, and lengthened out
To deathless pain? How gladly would I meet
Mortality, my sentence, and be earth
Insensible! how glad would lay me down
As in my mother’s lap!”
—John Milton (1608–1674)
“Our own country furnishes antiquities as ancient and durable, and as useful, as any; rocks at least as well covered with lichens, and a soil which, if it is virgin, is but virgin mould, the very dust of nature. What if we cannot read Rome or Greece, Etruria or Carthage, or Egypt or Babylon, on these; are our cliffs bare?”
—Henry David Thoreau (1817–1862)
