Abstract:

Results of the chemical composition measurement of gaseous products and particulate matter upon smoldering combustion of dominating vegetation of Siberian boreal forest (pine tree (Pinus sylvestris), Siberian larch (Larix sibirica), marsh tea (Ledum palustre), and lichen (Cladonia sp.), are presented. Experiments were conducted using a laboratory setup. The smoke emitted was first deposited on a glass-fiber filter and then frozen out by cooling at -50°C. The chemical composition of the smoldering combustion products of forest materials was determined by gas chromatography/mass spectrometry method. Guaiacol (2 methoxyphenol) and its substitutes, resin acids and other compounds are emitted by the smoldering combustion of pine tree and Siberian larch. Syringol (2,6-dimethoxyphenol) and its substitutes are emitted by marsh tea burning. The content of levoglucosan in lichen smoke emission is shown to be much higher than that of other burned materials. It has been established that 1-2% of the burned wood combustible materials enter the atmosphere as particulate emission and the same is the portion of gaseous products.
