Overall changes in energy-related emissions by main group of air pollutants in the EU-27, 1990-2005
Emissions of the secondary particulate precursor species are weighted by a particle formation factor prior to aggregation: primary PM10 = 1, SO2 = 0.54, NOX = 0.88, and (NH3) = 0.64 (de Leeuw, 2002).
