SCHEDULE 5 Minimum number of sampling points

PART 2 Group A pollutants: limit values for the protection of ecosystems or vegetation
3 The following table sets out the minimum number of sampling points for fixed measurements to assess compliance with limit values for the protection of ecosystems or vegetation in zones other than agglomerations.
Where maximum concentrations exceed the upper assessment threshold	Where maximum concentrations are between the upper and lower assessment thresholds
1 station every 20,000 km2	1 station every 40,000 km2
4 In island zones the number of sampling points for fixed measurement shall be calculated taking into account the likely distribution patterns of ambient-air pollution and the potential exposure of ecosystems or vegetation.
