Exposure to PM10 daily mean

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

In 2024, 8% of the Belgian population was exposed to at least one daily average PM₁₀ concentration above 50 µg/m³. The highest number of exposures was 2 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.

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.
