Environment. A brief episode of ozone pollution in Donon

A short episode of ozone pollution was measured this Tuesday, June 26, by the ATMO Grand Est, responsible for air quality monitoring and forecasting, at the Donon station.

This “summer” episode is due to the formation of ozone from volatile organic compounds (VOCs) and nitrogen oxides from human activities (traffic, industry, residential, etc.) under the influence of strong solar radiation and high radiation. temperatures.

The ozone recommendation limit of 180 micrograms per m3 was exceeded in Donona within an hour and returned to normal values. Scattered thunderstorms during the evening helped reduce these concentrations. However, ozone levels should remain high this Thursday, June 27, according to forecasters.
