ABSTRACT- During Spring 2002, high volume air samples were collected for semi-volatile organic compounds (SOCs) at Cheeka Peak Observatory, which is located on the tip of the Olympic Peninsula in the state of Washington. These samples were collected in conjunction with the University of Washingtons PHOBEA2 campaign and NOAAs ITCT 2K2 campaign to study trans-Pacific atmospheric transport of pollutants. The samples were analyzed for a wide range of SOCs, including organochlorine pesticides, current use pesticides, and polycyclic aromatic hydrocarbons. An Accelerated Solvent Extraction system was used to clean and extract the polyurethane foam plugs that were used to trap gas-phase SOCs. The concentration of these SOCs in air was correlated with air trajectories and the concentration of other air pollutants in an attempt to distinguish between Asian and North American sources.

Key words: atmosphere, long-range transport, semi-volatile organic compounds, pacific northwest of the U.S.
