Are Aerosols dangerous? • The air we breathe always contains solid particles or droplets and is therefore an aerosol. • These aerosol particles can
When humans breathe, talk, sing, cough or sneeze, the emitted respiratory droplets mix in the surrounding air and form an aerosol. Aerosols are mixtures of small liquid and/or solid particles dispersed in a gas. There are three broad categories of aerosols: Primary atmospheric aerosols, which are aerosols that make it into Are Aerosols dangerous? • The air we breathe always contains solid particles or droplets and is therefore an aerosol. • These aerosol particles can be from natural sources or man-made sources • Sometimes the particles are of type that, at sufficient concentration, are toxic to our body.

Dental aerosols can pose risks to the clinician, staff, and other patients. Introduction An aerosol is a suspension of particles in a gas and an atmosphere aerosol consists of particles that remain aloft in air.
