The information level is lower than the alarm level, but can still mean that people who are sensitive to air pollution may display breathing difficulties.
A value of 217 micrograms per cubic metre was recorded in the southern city of Mons on Wednesday. The highest figure for Flanders was 205 micrograms. The Interregional Cell for the Environment says it's not unlikely that the alarm level of 240 micrograms/m3 could be reached today.
Air pollution plus tropical temperatures and sun result in heightened levels of ozone in the air. Idegem and Dessel (both 187), Sint-Pieters-Leeuw (194), Walshoutem (199), Bree (200) and Aarschot (201) all recorded worrying levels of ozone concentration yesterday.
People who are sensitive to air pollution, i.e. children, the elderly and people with breathing difficulties, should not strain themselves in the outdoors between the hours of noon and 10PM. As soon as the alarm level is exceeded this warning will affect everybody!
