The environment in which we are surrounded is the sum total of living organisms like animals, plants and microorganisms and their actions which undergo constant changes, especially by human activity. It provides conditions for development and growth and also that of danger and damage. Aerosols are such products seen in the urban ecosystems in various forms. The presence of aerosols in earth's atmosphere can influence earth's climate, as well as human health. As they are omnipresent they form a universal challenge to all the dentists around the world to control their transmission and inhibit their action. Hence, in this article we have reviewed various properties of aerosols, methods of measurements, mode of transmission and standard precautions to be followed.
