摘要在克里特岛的一个城市沿海地区，季节性采集的大气颗粒物样本中的脂质浓度被测定。通过GC-FID和GC-MS分析，确定了正构烷烃、正庚烷和甾烷、多环芳烃、脂肪醇、脂肪酸和脂肪酸选择性等脂肪化合物类别。正构烷烃的浓度为56-215 ng/m~3，多环芳烃为10-52 ng/m~3，脂肪醇为2-31 ng/m~3，脂肪酸为13-279 ng/m~3，脂肪酸盐为24-220 ng/m~3。ω-氧化羧酸也被确定为盐，表明不饱和脂肪酸在大气中被氧化。
SummaryThe 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. ω-Oxocarboxylic acids were also determined as salts, indicating the atmospheric oxidation of unsaturated fatty acids.
