Joint study of inorganic and hydrocarbon components of tropospheric aerosol in the atmosphere over the boreal area of the south of Western Siberia by using the 'Optik' Tupolev-134 aircraft laboratory

摘要

The article provides a joint analysis of the aerosol chemical composition data on the content of inorganic components (chemical elements and ions) and hydrocarbons (n-alkanes) as part of an aerosol over Karakansky bor (a large forest with prevailing coniferous trees on the right bank of the southern part of the Novosibirsk reservoir) in aircraft sounding from 2011 to 2016. Correlation analysis showed the greatest connection with n-alkanes of three metals - copper, cobalt and aluminum, especially copper and cobalt, with 5-6 hydrocarbon homologues right away Sodium, potassium, calcium and barium correlate with 1-2 n-alkanes. Soil aluminum and silicon, and a number of other trace elements find a connection with 1-3 n-alkanes. The homologs that are often correlated with one metal are consistently in the same row, which may indicate a significant catalytic activity of this metal in the atmosphere.
