United States Forest Service, Deschutes National Forest, Bend, Oregon

Creator:: Harney, Joshua M.
Abstract:: On January 5, 2000, the National Institute for Occupational Safety and Health (NIOSH) received a request for a health hazard evaluation (HHE) from the United States Forest Service (USFS), Region 6, Office of Natural Resources. The request listed nausea, rashes, headaches, and dizziness as symptoms reported by Foresters who use...

Application of nitrogen stable isotopes to identify sources of nutrient pollution : a management tool?

Creator:: Redon, Elizabeth A.
Abstract:: Nutrient pollution may perhaps be one of the oldest water quality problems and has recently been considered as one of the greatest threats to estuarine and coastal waters. Excessive nutrient loads have had a vast array of impacts on estuarine and coastal ecosystems globally. Direct negative effects include: shading out...

A complex signal to noise problem : determining the aerosol indirect effect from observations of ship tracks in AVHRR data

Creator:: Walsh, Christopher D.
Abstract:: Cloud reflectivity is a function of cloud liquid water content and droplet number concentration. Since cloud droplets form around pre-existing aerosol particles, cloud droplet number concentration depends on the availability of particles that can serve as cloud condensation nuclei. Given constant liquid water amount, increased availability of cloud condensation nuclei...
Resource Type:: Masters Thesis
Full Text:: particulate pollution on cloud properties is one of the least understood areas of climate forcing and

A human health risk assessment of hazardous air pollutants in Portland, Oregon

Creator:: Tam, Bonnie
Abstract:: In 1990, the Clean Air Act (CAA) Amendments authorized the regulation of 188 hazardous air pollutants (HAP). Exposure to HAPs at sufficient concentrations and durations can increase both cancer and serious adverse non-carcinogenic effects. The purpose of this study was to conduct a human health risk assessment using data of...
Resource Type:: Masters Thesis
Full Text:: realized that air pollution problems in specific cities were unique to their respective air pollution

Atmospheric transport of anthropogenic semi-volatile organic compounds to the Olympic Peninsula of Washington State

Creator:: Killin, Robert K.
Abstract:: Ambient high-volume (hi-vol) air samples were collected between March 15th and May 30th 2002, at Cheeka Peak Observatory (CPO), located on the tip of the Olympic Peninsula, Washington State. This sampling campaign was in conjunction with the 2002 Inter-Continental Transport and Chemical Transformation (ITCT 2K2) Campaign and the Photochemical Ozone...

Bioindication of air quality in forests of northern and central California using epiphytic macrolichen communities

Creator:: Jovan, Sarah
Abstract:: The unifying purpose of this dissertation was to describe, model, and map relationships between epiphvtic macrolichen communities and air quality in Ibrests of northern and central California. First, multivariate analyses were used to subdivide the large study area into three model areas with similar climate, topography, and lichen communities: the...

Lichen response to the environment and forest structure in the western Cascades of Oregon

Creator:: Martin, Erin P.
Abstract:: Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...

Using ship tracks to characterize the effects of haze on cloud properties

Creator:: Segrin, Matthew S.
Abstract:: 1-km MODIS observations of ship tracks off the west coast of the U.S. are used to characterize changes in cloud visible optical depths, cloud droplet radii, cloud cover fraction, and column cloud liquid water amount as low-level marine clouds respond to particle pollution from underlying ships. This study re-examines the...
Resource Type:: Masters Thesis
Full Text:: was partly due to the mixing of dry continental air and partly due to the pollution plumes from

Semi-volatile fluorinated organic compounds in Asian and Pacific Northwestern U.S. air masses

Creator:: Piekarz, Arkadiusz M.
Abstract:: Current studies suggest that perfluorinated organic compounds, such as fluorotelomer alcohols (FtOHs) in the troposphere, may be precursors of perfluorocarboxylic acids and perfluorosulfonates in remote regions. Fluorinated organic compounds were investigated in archived extracts collected from remote locations in Okinawa, Japan (HSO) and Mount Bachelor, Oregon (MBO) during the springs...
