PM10 particle pollution
In the Hauts-de-France region, the departments of the North and Pas-de-Calais are also affected by this air pollution, this Friday, February 14 in the Department of Oise. This is pollution with the so -called PM10 particles (the PM10 bring together the particles of diameter less than 10 µm).
The toxicity of suspended particles is essentially due to the particles of diameter less than 10 µm. They can be issued directly in air by anthropogenic activities (industry, residential, agriculture, transport) and by natural sources (forest fires, volcanic eruptions, etc.). Particles can also be formed directly in the atmosphere by physico-chemical reactions between pollutants already present in the atmosphere.
Reduced speed

- at 110 km/h on motorways normally limited to 130 km/h
- at 90 km/h on the portions of highways and national and departmental roads normally limited to 110 km/h
- At 80 km/h for heavy goods vehicles over 3.5 tonnes.
The regional prefecture explains that the new speed limitations on the roads of the department take effect this Friday, February 14 from 6 p.m. and will be valid until this Saturday, February 15, 11:59 p.m.
In addition to these decisions, the regional prefect prohibits any burning of green waste in the open air. It also pronounces a ban on the use of individual wood, extra or approval, non -efficient heating devices.
