The authorized speed will be reduced by 20 km / h in Île-de-France on Friday due to a “persistent” episode of ozone pollution, the police headquarters announced on Thursday.
The maximum authorized speed is lowered to 110 km/h on the highway, to 90 km/h on roads normally limited to 110 km/h and to 70 km/h on those usually limited to 80 or 90 km/h, details a statement.
Open burning operations are also prohibited. Airparif, the association for monitoring air quality in Île-de-France, plans for Friday to exceed the information-recommendation threshold set at 180 µg / m³. This episode of pollution, which began on Thursday, is a “persistent episode”, “which may constitute a risk to health”.
