Abstract:

In a Large aerosol chamber of the IAO SB RAS, experiments were carried out to simulate the smoke aerosol formed as a result of burning pine wood, with different ratios of smoldering and flame combustion modes. The variability of the chemical composition of mixed smokes at the stage of their formation and during 2-day aging under UV irradiation and dark aging was revealed. The dependence of the mass concentrations of light-absorbing carbon-containing particles on the mixing parameter of smoldering and flame combustion modes is considered.

Keywords:
