摘要

The wildland fires of 2000 comprised one of the most severe fire seasons is U.S. history, and had a direct impact on the city of Missoula, Montana. This paper presents the results of chemical sampling conducted before, during, and after the 2000 fire season in Missoula, Montana, and provides a detailed characterization of particulate and chemical emissions from extensive wildland fires. We summarize levels of PM_(2.5), trace elements (13 - 82), anions (fluoride, chloride, nitrate, and sulfate), cations (ammonium, magnesium, calcium, potassium, and sodium). Organic Carbon (OC), Elemental Carbon (EC), and Total Carbon (TC) collected on the PM_(2.5) filters. We also quantified 61 semi-volatile organic compounds (SVOCs) and 54 volatile organic compounds (VOCs). In addition to the Chemical Mass Balance (CMB) sampling, particulate information collected by the Montana Department of Environmental Quality is provided. This includes PM_(2.5) data collected every 3 days in Missoula and Hamilton (46 miles south) throughout the fire season. Missoula is located in the Rocky Mountains of western Montana at an elevation of 3,200 feet. With a population of over 70,000 inhabitants, Missoula is the largest urban area in the United States completely surrounded by the Rocky Mountains. During the 2000 fire season, an ongoing project conducted by The University of Montana, Department of Chemistry, was already collecting samples for a CMB study to identify the sources of air pollution in the Missoula Valley. This sampling study focuses on PM_(2.5), VOCs, and SVOCs.
