Abstract
In this paper, some methodical aspects of airborne sampling of aerosol particles, extraction of organic matter form aerosol samples, and identification of organic compounds are discussed. The investigation of a possible influence of aviation fuel and lubricants (kerosene, oil, hydraulic fluid) on measurement data has been performed. The composition of organic particulate matter sampled during winter and spring 2013 in the 500-7000 m atmospheric layer over Karakan Pine Forest located near the shore of Novosibirsk reservoir has been analyzed. The following compounds were identified: n-alkanes, cyclanes, and alkylarenes. For the first time in the particulate matter sampled in West Siberia the saturated cyclic and alkyl aromatic hydrocarbons have been revealed.
