Observed concentrations of NO 2
in 2017. Dots in the last two colour categories correspond to values above the EU annual limit value
and the equal WHO air quality guidelines (40 μg/m 3 ). Only stations with > 75 % of valid data have been included in the map. The French
overseas territories’ stations are not shown in the map but can be found at EEA (2019j).
