The annual mean ozone concentration is a measure of the background concentration in Belgium. It is clear that the ozone values will, in general, be higher in rural Wallonia than in Flanders and urban Brussels. The reason for this is that more ozone is broken down by NO because of the higher NOx emissions. By contrast, further downwind of the NOx emissions less ozone is broken down.
