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:
“The sun rarely shines in history, what with the dust and confusion; and when we meet with any cheering fact which implies the presence of this luminary, we excerpt and modernize it.”
—Henry David Thoreau (1817–1862)
“A sudden light transfigures a trivial thing, a weather-vane, a wind-mill, a winnowing flail, the dust in the barn door; a moment,—and the thing has vanished, because it was pure effect; but it leaves a relish behind it, a longing that the accident may happen again.”
—Walter Pater (1839–1894)
“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)
