| For nitrogen dioxide, particulate matter, benzene and carbon monoxide: to include at least one urban background monitoring station and one traffic-orientated station provided this does not increase the number of sampling points. For these pollutants, the total number of urban-background stations and the total number of traffic oriented stations in a Member State required under Section A(1) shall not differ by more than a factor of 2. Sampling points with exceedances of the limit value for PM10 within the last three years shall be maintained, unless a relocation is necessary owing to special circumstances, in particular spatial development. | ||||
| Where PM2,5 and PM10 are measured in accordance with Article 8 at the same monitoring station, these shall count as two separate sampling points.
