About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE). Ozone in the troposphere. It is considered a secondary air pollutant because it is produced by the reaction of solar ULTRAVIOLET RAYS with other AIR POLLUTANTS and because of its harmful effects on the respiratory system and the environment.
