  Identification of emission sources from data of PM2.5 chemical speciation measured with automatic monitors: application in a coastal site of the Mediterranean basin

  ABSTRACT
  High-time resolution (1 hour) measurements of 11 species (organic carbon, elemental carbon, chloride, nitrite, nitrate, sulfate, sodium, ammonium, potassium, magnesium, calcium) within the PM_2.5 were conducted, from 3rd May to 30th June 2010, in a coastal site of Basilicata (Italy). Acquired data were analysed through Positive Matrix Factorization (PMF) method in order to individuate potential emission sources. This source apportionment evaluation revealed 5 factors separated as Vehicular traffic, Combustion of biomass, Secondary aerosol, Aged marine, Marine fresh and Dust. For each factor were defined profile, temporal trend, 24h-cycle and percentage contribution to measured PM_2.5, also emphasizing the relationship between factors and different wind conditions.
