AB: The atmospheric transport of anthropogenic semi-volatile organic compounds (SOCs) from Asia to the United States west coast may be important for determining the chemical fate and environmental impacts of these compounds. SOCs were measured using a high volume air sampler located at Cheeka Peak Observatory (CPO) in the state of Washington on the tip of the Olympic Peninsula from January 28th, 2003 to December 10th, 2003. Throughout this time period, dust and smoke events were observed during June 2-6th and August 5th of 2003 by the aerosol monitoring system NAAPS (Navy Aerosol Analysis and Prediction System). Air samples were collected with a quartz fiber filter to trap the particulate phase SOCs and a polyurethane foam and XAD-2 resin combination to trap the gas phase SOCs. The samples were accelerated solvent extracted and analyzed using Electron Impact and Electron Capture Negative Ionization Gas Chromatographic Mass Spectrometry. The target analytes were anthropogenic SOCs including markers for incomplete combustion (polyaromatic hydrocarbons), agriculture (pesticides such as organochlorines, organophosphates, and triazines), and industrial and urban sources (polychlorinated biphenyls). Potential source locations were determined using NOAA hysplit back trajectories along with satellite and meteorological data.
