Abstract
The volume mixing ratios of non-methane hydrocarbons including saturated, unsaturated and
 aromatic ones (C2 to C8 as non methane hydrocarbons, NMHCS) were measured at three
 distinct sites (natural, rural, urban) in the lower troposphere of the Eastern Mediterranean
 from February 2006 to March 2007. Average concentrations for most of the NMHC show clear
 seasonal variations along the year mainly attributed to photochemistry. Significant
 correlations found among various hydrocarbons indicate contribution from mobile and
 stationary sources (exhaust and combustion). Leakages from natural gas (NG) or liquefied
 petroleum gas (LPG) probably from the continental platforms may account for important
 sources for the background concentration of ethane and propane in the area. Isoprene has
 been found to have mostly a biogenic source but its dual anthropogenic–biogenic origin was
 also evident at the rural site.
