Fine particles (PM2.5) are air aerosols smaller than 2.5 µm.
Legislation
In the European Union there is a new directive on air pollution: http://register.consilium.europa.eu/pdf/en/07/st03/st03696.en07.pdf
ANNEX XIV NATIONAL EXPOSURE REDUCTION TARGET, TARGET VALUE AND LIMIT VALUE FOR PM2,5
A. AVERAGE EXPOSURE INDICATOR
The Average Exposure Indicator expressed in Gg/m3 (AEI) shall be based upon measurements in urban background locations in zones and agglomerations throughout the territory of a Member State. It should be assessed as a 3-calendar year running annual mean concentration averaged over all sampling points established pursuant to Section B of Annex V. The AEI for the reference year 2010 shall be the mean concentration of the years 2008, 2009 and 2010.
However, where data are not available for 2008, Member States may use the mean concentration of the years 2009 and 2010 or the mean concentration of the years 2009, 2010 and 2011. Member States making use of these possibilities shall communicate their decisions to the Commission by ...∗.
The AEI for the year 2020 shall be the 3-year running mean concentration averaged over all those sampling points for the years 2018, 2019 and 2020. The AEI is used for the examination whether the national exposure reduction target is met.
The AEI for the year 2015 shall be the 3-year running mean concentration averaged over all those sampling points for the years 2013, 2014 and 2015. The AEI is used for the examination whether the exposure concentration obligation is met.

B. NATIONAL EXPOSURE REDUCTION TARGET
Exposure Reduction Target relative to the AEI in 2010 Year by which the exposure reduction target should be met
Initial concentration in Gg/m3 Reduction target in percent < 8,5=8,5 0 % > 8,5 – < 13 10 % = 13 – < 18 15 % = 18 – < 22 20 % ≥ 22 All appropriate measures to achieve 18 μg/m3 2020
Where the AEI in the reference year is 8,5 Gg/m3 or less the exposure reduction target shall be zero. The reduction target shall be zero also in cases where the AEI reaches the level of 8,5 Gg/m3 at any point of time during the period from 2010 to 2020 and is maintained at or below that level.
