Observed concentrations of PM10 in 2018. The map shows the 90.4 percentile of the PM10 daily mean concentrations, representing the 36th highest value in a complete series. It is related to the PM10 daily limit value, allowing 35 exceedances of the 50 μg/m3 threshold over 1 year. Dots in the last two colour categories indicate stations with concentrations above this daily limit value. Only stations with more than 75 % of valid data have been included in the map. The possibility of subtracting contributions to the measured concentrations from natural sources and winter road sanding/salting has not been considered.
