1 additional sampling point per 4 million inhabitants

For each zone, the minimum number of sampling points for fixed measurements set out in Tables 1–4 of this Point shall include at least one background location sampling point and one sampling point at an air pollution hotspot according to Point B of Annex IV provided this does not increase the number of sampling points. For nitrogen dioxide, particulate matter, benzene and carbon monoxide, this shall include at least one sampling point focused on measuring contribution from transport emissions. However, in the cases where there is only one sampling point required, this shall be located at an air pollution hotspot.

For each zone, for nitrogen dioxide, particulate matter, benzene and carbon monoxide, the total number of urban background location sampling points and the total number of sampling points required at air pollution hotspots shall not differ by more than a factor of 2. The number of PM2,5 and nitrogen dioxide sampling points at urban background locations shall meet the requirements set out in Point B.
