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:
“No matter how vital experience might be while you lived it, no sooner was it ended and dead than it became as lifeless as the piles of dry dust in a school history book.”
—Ellen Glasgow (18741945)
“Of comfort no man speak.
Lets talk of graves, of worms and epitaphs,
Make dust our paper, and with rainy eyes
Write sorrow on the bosom of the earth.
Lets choose executors and talk of wills.”
—William Shakespeare (15641616)
“The Indian attitude toward the land was expressed by a Crow named Curly: The soil you see is not ordinary soilit is the dust of the blood, the flesh, and the bones of our ancestors. You will have to dig down to find Natures earth, for the upper portion is Crow, my blood and my dead. I do not want to give it up.”
