Dust - Wikipedia, the free encyclopedia
Quote:
for minute solid particles with diameters less than 500 micrometers. On Earth, dust occurs in the atmosphere from various sources; soil dust lifted up by wind, volcanic eruptions, and pollution are some examples. Airborne dust is considered an aerosol and can have a strong local radiative forcing on the atmosphere and significant effects on climate. In addition, if enough of the minute particles are dispersed within the air in a given area (such as flour or coal dust), under certain circumstances this can be an explosion hazard.
Dust in homes, offices, and other human environments is mainly generated by humans mainly from their skin cells that slough off.[1](Some comes from domesticated pets such as dogs, cats and birds). Some atmospheric dust from the outdoors is also present.[2] On average, approximately 6 mg/m³/day of house dust is formed in private households, depending primarily on the amount of time spent at home.[3] "Dust bunnies" are little clumps of fluff that form when sufficient dust accumulates. Dust is also referred to as "fluff", "fuzz", and "pie" [citation needed] and is known to worsen hayfever.
