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:
“Lo, thus, as prostrate, ‘In the dust I write
My heart’s deep languor and my soul’s sad tears.’
Yet why evoke the spectres of black night
To blot the sunshine of exultant years?”
—James Thomson (1834–1882)
“Tell me not, in mournful numbers,
Life is but an empty dream!—
For the soul is dead that slumbers,
And things are not what they seem.
Life is real! Life is earnest!
And the grave is not its goal;
Dust thou art, to dust returnest,
Was not spoken of the soul.”
—Henry Wadsworth Longfellow (1809–1882)
“And I have seen dust from the walls of institutions,
Finer than flour, alive, more dangerous than silica,
Sift, almost invisible, through long afternoons of tedium,”
—Theodore Roethke (1908–1963)
