DETERMINATION OF ALIPHATIC AND AROMATIC-COMPOUNDS IN AEROSOLS COLLECTED AT 2 SEMIRURAL STATIONS IN MAJORCA (SPAIN)

A study of the aliphatic and aromatic hydrocarbons (PAHs) present in t he aerosols collected at two semi-rural stations located in the island of Majorca (Spain) has been carried out. A total of 27 aliphatic hydr ocarbons -ranging from C-18 to C (46) and the PAHs recommended by the American EPA with the only the substitution of acenaphthylene by benzo (e)pyrene have been studied. Results show that most of the aliphatic h ydrocarbons (C-26-C-45) originate from one or several common sources w hich are probably of biogenic type, since the Value of the CPI for the two stations is close to unity. Several common sources have been also observed in aromatic hydrocarbons which through characteristic ratios calculated from well established sources have been identified as: veh icles, wood and coal soots, residential furnaces and coal combustion.
