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:

    Could slavery suggest a more complete servility than some of these journals exhibit? Is there any dust which their conduct does not lick, and make fouler still with its slime?
    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;
    Percy Bysshe Shelley (1792–1822)

    Dust rises from the main road and old Délira is stooping in front of her hut. She doesn’t look up, she softly shakes her head, her headkerchief all askew, letting out a strand of grey hair powdered, it appears, with the same dust pouring through her fingers like a rosary of misery. She repeats, “we will all die”, and she calls on the good Lord.
    Jacques Roumain (1907–1945)
