Scope note: The unstable triatomic form of oxygen, O3. It is a powerful oxidant that is produced for various chemical and industrial uses. Its production is also catalyzed in the ATMOSPHERE by ULTRAVIOLET RAY irradiation of oxygen or other ozone precursors such as VOLATILE ORGANIC COMPOUNDS and NITROGEN OXIDES. About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE).

Ozone - Preferred
Concept UI M0015711
Scope note The unstable triatomic form of oxygen, O3. It is a powerful oxidant that is produced for various chemical and industrial uses. Its production is also catalyzed in the ATMOSPHERE by ULTRAVIOLET RAY irradiation of oxygen or other ozone precursors such as VOLATILE ORGANIC COMPOUNDS and NITROGEN OXIDES. About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE).
Preferred term Ozone
Tropospheric Ozone - Narrower
Concept UI M0570487
Scope note 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.
Preferred term Tropospheric Ozone
Entry term(s) Level Ozone, Low
Low Level Ozone
Ozone, Low Level
Ozone, Tropospheric
Ground Level Ozone - Narrower
Concept UI M0570491
Scope note Ozone in the lower troposphere, just above the surface of the Earth.
Preferred term Ground Level Ozone
Entry term(s) Level Ozone, Ground
Ozone, Ground Level
