This Friday, December 27, the air is judged “bad” in Tarn-et-Garonne, and will also be so on Saturday in six departments of Occitanie, including Gard and Haute-Garonne. The accumulation of fine particles, favored by stable weather conditions, is at the origin of this pollution episode.
The air quality index is “poor” this Friday, December 27 in Tarn-et-Garonne. And he will be too Saturday December 28 in Gard, Gers, Haute-Garonne, Hautes-Pyrénées, Tarn and again in Tarn-et-Garonneaccording to Atmo Occitanie forecasts. Furthermore, a “degraded” index is reported in other departments of the region.
Why is the air quality bad in part of Occitania?
“The air quality index could be degraded, or even poor, in part of the region due to the increase in fine particles favored by weather conditions », according to Atmo Occitanie. The conditions the agency is referring to include a stable air mass and a lack of wind. Fine suspended particles are therefore not dissipated in space. They accumulate and harm air quality.
The main sources of these fine particles include domestic heating, road transport and certain industrial activities. The situation will continue on Saturday due to the same phenomenon, marked by the absence of wind, which prevents the dispersion of atmospheric pollutants.
Vigilance for sensitive people
Faced with these conditions, Atmo Occitanie recommends that sensitive and vulnerable populations (children, elderly people, people suffering from respiratory or cardiovascular diseases) limit physical exertion outdoorsparticularly in areas where the index is “bad”. The body advises you to pay attention to possible symptoms, such as eye irritation, sore throat or persistent cough.
