Measurements of the smoke emission chemical composition upon simulated combustion of forest fuel materials in a large aerosol chamber

In the IOA SB RAS, a large aerosol chamber was used to perform 20 experiments on the burning of forest fuel materials (pine wood, coniferous litter) of two types in smoldering/flame combustion modes of different ratios. The chemical composition (PM, OC, EC) of fresh smokes (2 hours after substrate ignition) and of aged aerosol (on the 1st and 2nd days) was determined in dark conditions. The variability of the main characteristics of smoke aerosol during its aging was analyzed with different contributions of smoldering and flame combustion modes.
