Isotope Composition of Pyrogenic Carbon of Various Origins

In the work, the isotopic composition of pyrogenic carbon samples of various origins was studied. The dependence of this composition on the isotopic composition of the source carbon source was determined using isotope ratio a mass spectrometer DELTA V Advantage (Thermo Fisher Scientific/USA–Germany) in the combination with an elemental analyzer Flash-2000. The studies showed that pyrogenic carbon produced after burning kerosene and its derivatives (δ13Ñ = –30 ‰) had the lightest isotope composition. The isotope composition of wood δ13Ñ = –27 ‰, and coal has a heavier isotope composition (δ13C = –24 ‰). The carbon isotope composition of dust particles sampled from the snowpack in different locations in Tomsk showed deviations from the δ13Ñ = –28.8 ‰ to δ13Ñ = –21.9 ‰
