Ambient air quality: limit values for sulphur dioxide, oxides of nitrogen, particulate matter and lead

1997/0266(SYN)
The Commission considers that this text represents an acceptable compromise, the level of ambition that it embodies remaining close to that of the original proposal. The text is the result of intensive negotiations, during which new technical information was brought forward, most notably on the comparability of different methods of measuring PM10. The resulting limit values are in some cases a weakening of the Commission's original proposal. Other aspects of the proposal have been strengthened, in particular by the addition of an alert threshold for NO2 and clarification of the new framework for providing regular information on air quality to the public. �
