P062: Particulate Emissions From Different Types of Biomass Burning

Biomass burning is a significant source of PM2.5, but few studies have addressed the chemical composition of PM2.5 emissions from various types of fires. This study quantified PM2.5 emissions from various types of prescribed burning activities using analysis of carbon, polar organic compounds, water-soluble potassium, and particle-bound mercury. Emissions were characterized for a series of prescribed burns in the Lake Tahoe Basin and controlled biomass combustion in a wood stove. In the field, emissions were collected from: landscape underburns and/ or pile burns. In a wood stove, burns included different fuel types from the Tahoe Basin, including logs, green foliage and branches.
