A stifling and… polluted Friday. In addition to approaching 40 ° C on Friday, the air in the Ile-de-France has been accumulating high levels of pollution for two days. “Ozone concentrations in Ile-de-France are gradually increasing. An exceeding of the information threshold (1st of the two thresholds in the event of a pollution episode) is scheduled for Friday, ”warns the Airparif organization.
Airparif thus predicts, for Friday July 31, an ozone concentration of between 170 and 200 µg / m³, ie a probable exceeding of the information threshold, set for this pollutant at 180 µg / m³.
As a result, the police prefecture announces the establishment of differentiated traffic, from Friday morning 5:30 a.m. and until 8 p.m., in the perimeter of the A86.
Controls "with discernment" on this day of departure on vacation
Only Crit'air 0, 1 and 2 vehicles will be allowed to circulate. Crit'air 5, Crit'air 4 (vehicles registered before 2006 for diesel, and before 1997 for gasoline) and Crit'air 3 vehicles are prohibited. The maximum speed will be reduced by 20 km / h on major roads. Ile-de-France residents, while heavy goods vehicles will have to bypass the region.
“The Prefecture of Police will put in place controls intended to ensure compliance with these measures. The Prefect of Police, however, asked his services to apply the controls concerning the differentiated traffic measure with discernment, given the departures on leave ”.
The anti-pollution package triggered in transport
