What is Urban Ozone?
A Manchester (UK) based research has found that the nationwide lockdown may be leading to the generation of a dangerous pollutant, urban ozone.
The Ozone is formed due to different factors in the Troposphere and the Stratosphere (where the protective ozone layer lies)..
The photochemical production of ozone may become more important in urban areas during summertime in these low conditions of oxides of nitrogen.
As nitrogen oxides reduce, photochemical production may become more efficient and can lead to higher ozone concentrations in the summertime.
The higher summer temperatures increase emissions of biogenic hydrocarbon from natural sources such as trees. These biogenic hydrocarbons significantly affect urban ozone levels.
While ozone is important for screening harmful solar UV radiation when present higher up in the atmosphere, it can be a danger at the Earth’s surface and can react to destroy or alter many biological molecules.
