An ozone concentration of 188 µg/m³ (the µg being known in scientific circles as a Dobson unit) was measured yesterday (Wednesday). This occurred around 7.00 p.m. in Dessel, in the Kempen. This measurement is higher than the European data threshold, which is fixed at 180 µg/m³.
This appears today on the website of the Flemish Environment Agency (Vlaamse Milieumaatschappij). This is the first time that this threshold has been exceeded this year in Belgium, the Interregional Environment Cell (known locally simply as Celine) has confirmed to the press agency Belga.
Increased concentrations of ozone were also detected yesterday evening (Wednesday) elsewhere in the north east of Flanders, such as in Bree (167 µg/m³), in Limburg.
Celine states that increased temperatures, sunshine, low winds and the accumulation of air pollutants are favoring ozone formation, both yesterday and in the days to come. Today (Thursday), ozone concentrations are set to reach between 125 to 185 µg/m³.
