The average concentrations of PM2.5 fine particles over 24 hours are always above 35µg/m3 in the three regions, indicates the Interregional Cell for the Environment (Celine) on Friday. Given that they should remain above this threshold for more than two consecutive days, the information and intervention phase has been activated in the Brussels Region since this Saturday.
The speed will therefore be limited to 50 km/h in the Brussels-Capital Region, on roads where you can usually drive at 90 or 70 km/h.
Speed controls will be reinforced by the police. The Villo! as well as metros, trams and STIB buses will be free until the end of the intervention phase. Wood heating will be prohibited from use if it is not the main means of heating the home. The average concentration of PM2.5 fine particles over 24 hours was at 10 a.m. 40 µg/m3 in Flanders, 39 in Brussels and 42 in Wallonia. Mainly emitted by exhaust gases and domestic heating, fine particles are toxic to health and can penetrate deep into the lungs.
Depending on their level of concentration, the duration of exposure and the sensitivity of the people exposed, they can promote the onset or aggravate the symptoms of respiratory and cardiovascular diseases. The high particulate concentrations are explained by the fact that air pollution – from industry, agriculture, traffic and building heating – is poorly dispersed due to unfavorable weather conditions (low wind). Due to the cold weather, emissions from heating buildings, mainly from wood-burning stoves, are also higher.
