| Zusammenfassung |
| In this paper we present the results 13-year study of aerosol chemical composition over
background region of Siberia. The Antonov-30 "OPTIK-E" airborne laboratory of the
Institute of Atmospheric Optics has been carrying out regular (monthly) airborne sounding
over southern regions of West Siberia since July 1997. Airborne surveys are mainly
performed over forested area near the boundary of Novosibirsk and Altai regions in the 500 to
7000 m atmospheric layer. Aerosols are sampled onto FPP filters, which then analyzed at the
Laboratory of Environmental Monitoring of Tomsk State University. The volume of air
aspirated through each filter is 1-4 m3. Physico-chemical techniques of quantitative analysis
are used to analyze the chemical composition of the aerosol (Si, Al, Fe, Mg, Ca, Ti, Cu, Mn,
Cr, Ag, Pb, Ni, Ba, Sn, V, Mo, Co, B, Be, K+, Na+, Cl-, SO42-, NO3-, Br-, F-,
NH4+).
Statistic analysis of mass concentrations of ions and elements showed that empiric
distributions for majority components can be described by logarithmically normal law. It is
verified by high values of correlation coefficients and Ï2-criterion between empiric and
theoretical distributions.
