DESCRIPTION:Civil aviation is fast-growing\, mainly driven by the developi
 ng economies and globalization. Despite the increased attention given to a
 ircraft emissions at ground level and air pollution in the vicinity of air
 ports\, the chemical and physical characterization of the airborne particu
 late matter has not been fully elucidated and the role of plume aging on i
 ts mass and composition is largely unknown. The project CHEERS (Chemical a
 nd Physical Properties and Source Apportionment of Airport Emissions in th
 e context of European Air Quality Directives) aims to investigate the impa
 cts of major airports upon local air quality and the apportionment of thos
 e impacts to aircraft\, road traffic and other emission sources typical of
  large cities holding large airports. This study investigates the contribu
 tion of the Airport of Venice (NE Italy) to black carbon\, total particle 
 number concentrations and particle number size distributions over a large 
 size range: 14 nm to 20 μm. Particle size spectra were used as input for 
 a positive matrix factorisation receptor model aiming to identify and quan
 tify the main potential sources of particles. Results revealed no signific
 antly elevated levels of black carbon and particle number concentration\, 
 but identified distinct diurnal profiles. Eight factors were apportioned b
 y receptor model analysis and interpreted as probable sources according to
  the size profiles\, directional association\, diurnal variation\, road an
 d airport traffic volumes and their relationships to micro-meteorology and
  air pollutants. \n
