Sahara sand: air quality degraded in France, Occitanie particularly concerned. The air quality index was described as “poor’ for this Sunday in the departments of Haute-Garonne, Gers, Ariège, Pyrénées-Orientales and Hautes-Pyrénés.
On Sunday, air quality will be degraded in several departments of France due to the arrival of a cloud of sand from the Sahara desert. This air mass, rich in desert particles, will increase the concentrations of PM10 particles in the territory.
