7. In the zones in which a Member State considers it necessary to limit or prevent a foreseeable increase in pollution by sulphur dioxide, oxides of nitrogen or suspended particulate matter it may continue to use the guide values for the protection of ecosystems laid down in Annex II to Directive 80/779/EEC and in Annex II to Directive 85/203/EEC.

Article 10 - Report and review

No later than 31 December 2003 the Commission shall submit to the European Parliament and the Council a report based on the experience acquired in the application of this Directive and, in particular, on the results of the most recent scientific research concerning the effects on human health and ecosystems of exposure to sulphur dioxide, nitrogen dioxide and oxides of nitrogen, different fractions of particulate matter and lead, and on technological developments including the progress achieved in methods of measuring and otherwise assessing concentrations of particulate matter in ambient air and the deposition of particulate matter and lead on surfaces.

With a view to maintaining a high level of protection of human health and the environment and taking into account the experience acquired in the application of this Directive in Member States including, in particular, the conditions as laid down in Annex VI under which measurement has been carried out, the aforementioned report will be accompanied by proposals for the amendment of this Directive if appropriate. In particular, the Commission will examine the limit values for the second stage for PM10 with a view to making them mandatory and will consider confirming or altering the limit values for the second stage and, if appropriate, for the first stage. In addition, the Commission will give particular attention to setting limit values for PM2,5 or different fractions of particulate matter, as appropriate. Furthermore the Commission will examine the annual limit value for the protection of human health for nitrogen dioxide and will make a proposal confirming or modifying that value. It will also examine the hourly limit value for nitrogen dioxide in the light of World Health Organisation guidelines and consider whether that limit value should be confirmed or altered.

The Commission will also consider whether alert thresholds can be set, consistent with other pollutants in this Directive, for PM10, PM2,5 or particular fractions of particulate matter, as appropriate.
