Observed concentrations of PM2.5 in 2017. The map shows the PM2.5 annual mean concentrations. Dots in the last two colour categories indicate stations with concentrations exceeding the limit value (25 μg/m3). Dots in the first colour category indicate stations reporting values below the WHO air quality guidance for PM2.5 (10 μg/m3). Only stations with more than 75 % of valid data have been included in the map.
