The two highest NO2 concentration classes (red and orange) correspond to the 2010 annual LV (40 μg/m3) and to the LV plus margin of tolerance (42 μg/m3). The two highest PM10 concentration classes (red and orange) correspond to the 2005 annual LV (40 μg/m3), and to a statistically derived level (31 μg/m3) corresponding to the 2005 daily LV. The lowest class corresponds to the WHO air quality guideline for PM10 of 20 μg/m3.
