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.

Threshold Categories
-
Deposition of PM is an important source of phosphorus (P) and sediment to Lake Tahoe, and leads to reductions in water clarity and decreases atmospheric visibility in the basin.

| 07/10/2017 6:54 AM | System | Objectives: The objective of this study was to quantify the PM2.5 emissions from various types of prescribed burning activities using analysis of carbon (elemental carbon: EC; organic carbon: OC; and total carbon: TC); polar organic compounds (12 different compounds and four functional classes); water soluble potassium (K+); and particle-bound mercury (PHg). |

| 07/10/2017 6:53 AM | System | Findings: Our data showed higher ratios of organic to elemental carbon in green fuels (19.2 ± 4.2) compared to dry wooden logs (7.3 ± 1.9) both in prescribed burns in the field and in controlled stove combustion, indicating that more moisture in green biomass resulted in more smoldering-phase combustion. Further, OC/EC ratios were lower in wood stove burns compared to prescribed burns in the field, which we attribute to higher combustion temperatures in wood stove burns. The suite of 12 select polar organic compounds showed that the most prevalent compounds emitted across all burns were levoglucosan, mannosan, and resin acids (dehydroabietic, pimaric, and abietic acids), while emissions of inositols and arabitols were only significant in combustion of leaves from a broadleaf shrub indicating their potential use as tracers for green foliage. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional findings |
