The map shows the 90.4 percentile 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. The red and dark-red dots 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.
