Deposition of Potassium on Chimney Wall from Wood Stove Smoke: Implication for the Influence of Domestic Biomass Burning on Atmospheric Aerosols

Based on the field studies of biomass burning plumes in Alaska, we hypothesized that potassium (K) may be significantly scavenged, during wood stove burning, as deposits inner wall chimney where temperature decreases with height. To test this hypothesis, analyzed deposit samples collected from a (6 m long) for measurement major ions and anhydrosugars including levoglucosan (Lev). Concentrations K were found to highest lower part decreasing trend height, whereas Lev showed an opposite lowest concentrations near bottom increase We detected anti-correlation between two components deposits, confirming is largely scavenged within while emitted ambient air. propose that, using K/Lev mass ratios, relative contributions open fires domestic aerosols can evaluated.
