According to the body responsible for the monitoring of air quality in the region, the particle concentration is expected to exceed Friday “alert threshold” of the public (80 µg/m3). On Thursday, the pollution should not exceed the “information threshold” of the public (50 micrograms/m3).
” We are in the information threshold, it means that there is already a pollution episode, it continues tomorrow [Friday] with an aggravation “, indicated to the AFP Karine Léger, spokesperson of Airparif.

According to Airparif, the pollution today is due to half the emissions from vehicles and half wood heating, mode of heating strongly particle emitter when the fireplace is open.
” there’s a little less crowded to Paris [because of holidays], but the greater paris area and the Ile-de-France are still a agglomeration consequent, ” underlines Karine Léger. “It also makes a lot more cold, so it was over heating “.
