The limit value is 50 µg PM10/m3 (24 hour average, i.e. daily), not to be exceeded more than 35 times a calendar year and to be met by 2005. Over the years 1997-2009 the total population for which exposure estimates are made, increased from 25 to 110 million people due to an increasing number of monitoring stations reporting air quality data under the Exchange of Information Decision. Year-to-year variations in exposure classes are partly caused by the changes in spatial coverage. Only urban and sub-urban background monitoring stations have been included in the calculations. Data for Cyprus, Greece, Luxembourg and Malta, are not included due to the geographical coverage of the Urban Audit.

The recommended temperature for a refrigerator is between 1 – 4 °C
and for the freezer it should be set at -18 °C. Each degree below these temperatures makes no difference as to how well the food is preserved, but it does increase energy consumption by approximately five per cent. Place a thermometer in the refrigerator and the freezer to check the temperature!
