    The 240 µg/m3 of ozone alert threshold was exceeded at 2 monitoring stations in Flanders at 3:00pm today, with 255 µg/m3 in Aarschot and 254 µg/m3 in Dessel. Ozone concentration levels exceeded the information threshold (180 µg/m3) at 8 monitoring stations, reveals the Belgian Interregional Environment Agency (IRCEL – CELINE) in a press release on Thursday.  High ozone concentration levels are currently being observed throughout the monitoring networks of all 3 regions, mostly in the east of the country, notes CELINE/IRCEL.  Ozone concentration levels remain below the information threshold in the west of the country however, but have exceeded it in the east, where it the level went over the alert threshold in various locations. Marked differences in temperatures and amount of sunlight between the east and the west of Belgium explain these great variations in concentration, adds the agency.

    CELINE/IRCEL expects the levels to go over the information threshold again in various locations in the next few hours. Levels will also probably break through the alert threshold in the east of the country. Ozone concentration levels will only start decreasing late in the evening, adds CELINE/IRCEL.
