Departments on the verge of asphyxiation. On Monday, Atmo, the agency responsible for measuring air quality, has issued a new bulletin of persistent pollution alert for the North and Pas-de-Calais. We will enter, on Tuesday, in the sixth consecutive day of
exceeding the regulatory thresholds for
The former Nord-Pas-de-Calais region has suffered since last Thursday an episode of persistent pollution to PM10, these fine particles from, among others, industry or traffic. It will therefore be six days that the regulatory threshold, set at 50 micrograms per cubic meter of air, is exceeded.
According to the prefecture, this pollution comes from the coast and does not evacuate due to weather conditions: high temperatures, no rain and wind … Despite the measures taken by the authorities, nothing works. The reduction of 20 km / h speeds on main roads, in force since Thursday, did not change the case. No more than the two days of differentiated traffic on the weekend. This pollution is all the more worrying because it persists even though human activity is reduced because of the Easter weekend.
For the day Tuesday, Atmo expects an air quality index of between 6 and 7 (mediocre) inland and 8 (bad) on the coast. The prefecture has logically maintained the speed restrictions on the roads. On the other hand, differentiated traffic, suspended for the weekend, will not be put in place again.
