Current research focuses on understanding the role atmospheric transport
plays in the deposition of semi-volatile organic compounds to high elevation
ecosystems along the Pacific Coast of North America. The research program seeks
to understand the relative impact of current and historical Asian, Pacific
Ocean, and North American sources on contamination at high elevations. Source
region identification and 'age' are determined using air trajectories and the
enantiomer ratios of chiral semi-volatile organic compounds. Sampling sites for
the research include Cheeka Peak Observatory (in collaboration with University
of Washington), the Pacific Ocean, and Mt. Ashland, Oregon. Analytes of interest
include organochlorine pesticides, current use pesticides, polycyclic aromatic
hydrocarbons, polybrominated diphenyl ethers, and fluorinated organic compounds.
The research utilizes chromatography, mass spectrometry, and novel methods of
sample extraction and purification.
