Metal Emissions from Prescribed Fires and Wildfires
Citation:
Holder, A. AND K. Boaggio. Metal Emissions from Prescribed Fires and Wildfires. Air Toxics and Risk Assessors Workgroup Call, Durham, North Carolina, November 18, 2021.
Impact/Purpose:
Wildland fires are one of the largest sources of particulate matter (PM) to the atmosphere. Although metals constitute a small fraction of those emissions they can lead to a measurable impact of the downwind PM composition. This presentation will provide an overview of metal emissions from different types of biomass fires, with a focus on Pb, a criteria pollutant. Additionally, results from a 13-year study of PM speciation monitoring data will be presented to show evidence of fire impacts of metals in the atmosphere.
