Exposure to PM10 annual mean
In 2015, no one in the Belgian population was exposed to annual mean concentrations above the European treshold of 40µg/m³. More than a quarter of the population (27%) was however still exposed to annual mean PM10 concentrations above the treshold of 20µg/m³ advised by the WHO. The declining slope in population exposure observed during the last years seems to have halted in 2015, with results similar to 2014. Yet, in 2015, 73% of the population was exposed to concentrations of PM10 beneath the treshold set by the WHO, while only in 2011, this was limited to 19% of the population or even to 2% in 2006.
