In the air quality directive (2008/EC/50), the EU has set two limit values for particulate matter (PM10) for the protection of human health: the PM10 daily mean value may not exceed 50 micrograms per cubic metre (µg/m3) more than 35 times in a year and the PM10 annual mean value may not exceed 40 micrograms per cubic metre (µg/m3). In some areas time extensions have been granted by DG Environment for meeting these limit values. Information about time extensions is provided by DG Environment at: http://ec.europa.eu/environment/air/quality/legislation/time_extensions.htm

Appreciate wildlife, but be sure to watch wild animals from a distance and avoid feeding them. Remember, the scent you leave when you touch a nest or a lair may scare the parents off for good. Instead of touching, try to find out more about them and maybe even discover how you can contribute to their protection.
