ANALYSIS OF ANTHROPOGENIC AND BIOGENIC LIPIDS IN THE AEROSOL OF A COASTAL AREA IN EAST MEDITERRANEAN-SEA

The concentrations of lipids were determined in atmospheric particle samples, collected seasonally, in an urban coastal area of the Island of Crete. Lipid compound classes, such as n-alkanes, hopanes and steranes, PAH, fatty alcohols, fatty acids and fatty acids selts, were determined by GC-FID and GC-MS analysis. The concentrations ranged between 56 - 215 ng/m3 for n-alkanes, 10 - 52 ng/m3 for PAH, 2 - 31 ng/m3 for fatty alcohols, 13 - 279 ng/m3 for fatty acids and 24 - 220 ng/m3 for fatty acid salts. omega-Oxocarboxylic acids were also determined as salts, indicating the atmospheric oxidation of unsaturated fatty acids.
