Exposure to PM10 daily mean

PM10 annual mean | PM10 daily mean | PM2.5 annual mean

In 2022, 91% of the Belgian population was exposed to at least one daily average PM10 concentration above 50 µg/m³. The highest number of exposures was 16 days, no one in Belgium was exposed to 35 exceedance days, the maximum according to the EU directive. A long-term decline in exposure to exceedances is visible. Compared to the years 2020 and 2021 impacted by the corona pandemic, more people were again exposed to exceedance days in 2022.

It is important to bear in mind the spatial resolution of the RIO interpolation technique: concentrations and exposures were calculated on 4 x 4 km² grids.

Evolution of the population exposure to days with a daily mean concentration of PM10 above 50 µg/m³. All data were calculated based on the RIO interpolation technique.
