An air pollution alert procedure is triggered by the Hérault prefecture for the day on Wednesday.
The department of Hérault is experiencing an episode of suspended particle pollution (PM 10). Air quality deteriorated on Tuesday due to the arrival of an air mass loaded with desert particles. These particles are added to those emitted locally by human activities (road traffic, industries, etc.).

Ozone concentrations (gas resulting from the transformation under the effect of the sun of gaseous pollutants emitted by human activities) are also relatively high due to meteorological conditions (strong sunshine, high temperatures).
The persistence of the pollution episode, with concentrations of PM 10 in the ambient air which will remain high, justifies triggering by Atmo Occitanie an alert procedure for Wednesday July 12 in the Hérault.
