Air quality (NO2)

CategoryHealth determinants
DimensionPhysical Env.
DescriptionAnnual mean µg/m3 (microgramme per cubic metre) for particulate matter with an aerodynamic diameter of less than or equal to 2.5 micrometres (PM2.5)
Indicator/Index/Metrics Annual mean NO2(μg/m3)=∑i=1nNO2in\text{Annual mean NO}_{2} (\mu g/m^3) = \frac{\sum_{i=1}^{n} \text{NO}_{2_i}}{n}
NoteThe annual NO2 guideline level recommended by the WHO is 5 µg/m³.
There are three interim targets for annual averages: 40, 30, and 20 µg/m³ for targets 1, 2, and 3, respectively.
