Is there a purpose for dust?

Dust influences the radiative balance of the planet in two different ways, either directly by scattering and absorbing incoming solar radiation, or indirectly by changing the optical properties of clouds, themselves an important player in the climate system.

Why Is dust a problem?

Dust includes tiny particles of debris and dead skin. Its small size means it can be inhaled and potentially evoke an immune reaction. Such allergic reactions may be minor or major depending on the individual. Dust can also serve as a “fomite”, potentially carrying viruses and possibly passing on infections.

Is most dust dead skin?

A commonly quoted statistic is that 80% of dust is made up of dead skin, but that’s actually a pretty small percentage. Dust in houses and offices is made up of a combination of pollen, hair, textile fibers, paper fibers, soil minerals, cosmic dust particles, and various other materials found in the local environment.

Why is house dust GREY?
