The figure shows the annual mean concentrations of particulate matter (PM2.5) observed at traffic stations in 2017.
The map shows the Percentile 90.4 of daily mean PM10 concentrations at traffic stations. This represents the 36th highest value in a complete series. It is related to the PM10 daily limit value, which allows 35 exceedances of the 50 µg/m3 threshold over a 1-year period. Dots in the last two colour categories indicate stations with concentrations above this daily limit value. Only stations for which more than 75 % of data are valid have been included in the map.
The figure shows the annual mean concentrations of nitrogen dioxide (NO2) observed at traffic stations in 2017.
The map shows the Percentile 90.4 of daily mean PM10 concentrations at background stations. This represents the 36th highest value in a complete series. It is related to the PM10 daily limit value, which allows 35 exceedances of the 50 μg/m3 threshold over a 1-year period. Dots in the last two colour categories indicate stations with exceedances of this daily limit value. Only stations for which more than 75 % of data are valid have been included in the map.
