Sampling points targeted at the protection of vegetation and natural ecosystems shall be sited more than 20 km away from agglomerations or more than 5 km away from other built-up areas, industrial installations or motorways or major roads with traffic counts of more than 50 000 vehicles per day, which means that a sampling point must be sited in such a way that the air sampled is representative of air quality in a surrounding area of at least 1 000 km. A Member State may provide for a sampling point to be sited at a lesser distance or to be representative of air quality in a less extended area, taking account of geographical conditions o ...[+++]r of the opportunities to protect particularly vulnerable areas.

Sampling points shall in general be sited in such a way as to avoid measuring very small micro-environments in their immediate vicinity, which means that a sampling point must be sited in such a way that the air sampled is representative of air quality for a street segment no less than 100 m length at traffic-orientated sites and at least 250 m × 250 m at industrial sites, where feasible.

the flow around the inlet sampling probe shall be unrestricted (free in an arc of at least 270°) without any obstructions affecting the airflow in the vicinity of the sampler (normally some metres away from buildings, balconies, trees and other obstacles and at least 0,5 m from the nearest building in the case of sampling points representing air quality at the building line),

The main shortcomings in the application of the bathing water Directive are: - the inadequate number of bathing areas where the required quality control measures are applied; - the frequency of sampling and the number of parameters examined; - the quality of water in many bathing areas which does not meet the requirements of the Directive despite the fact that the deadline for compliance was the end of 1985. - Environment: quality of the air As a result of proceedings initiated by the Commission concerning air pollution in Dublin and Athens, measures have been adopted which should lead to an improvement of the quality of the air in these two cities.
