[5] Dust in the atmosphere is produced by saltation and abrasive sandblasting of sand-sized grains, and it is transported through the troposphere. This airborne dust is considered an aerosol, and once in the atmosphere, it can produce strong local radiative forcing.
Dust is made up of various indoor and outdoor particles, like dead skin cells, dust mites, soil, and pet dander. Poorly maintained HVAC systems and high humidity can lead to higher levels of dust.
Dust is a major reservoir for substances that can trigger respiratory issues, including the waste products and body fragments of dust mites, which contain potent digestive enzymes.
Dust, in general, is any microscopic, powderlike particle or collection of powderlike particles that is made up of sand, soil, fragments of organic tissue, or other materials and is both light enough to be carried by the wind and heavy enough to be deposited on a surface.
