Factors influencing the atmospheric aerosol composition at two sites in western Oregon

Creator:: Ko, Lih-jong
Abstract:: Fine and coarse particles were collected for eight weeks during the summer of 1991, at a coastal site (Yaquina Head) and a non-industrial site (Corvallis) in Western Oregon to characterize the aerosol composition and evaluate whether the sites are appropriate for sampling "background" marine air. Concentrations of up to 11...

Nitrate and pesticide transport under pear production in clay and sandy soil

Creator:: Cao, Weidong
Abstract:: Groundwater contamination on irrigated land is of concern in this nation and around the world. In order to reduce the potential of groundwater contamination by agricultural practices such as irrigation, fertilizer and pesticide application, vadose-zone monitoring and sampling are needed. The main objective of this study was to evaluate impacts...

Harvestable moss : communities, hosts, and accumulation

Creator:: Peck, JeriLynn E.
Abstract:: With the increased recognition of moss as a secondary forest product has come an increased concern for the ecological ramifications of moss harvest. Three issues of primary concern are (1) characterizing the epiphyte communities impacted by harvest, (2) assessing the host preferences of these epiphytes, and (3) describing the availability...

Application of nonequilibrium ecology to managed riparian ecosystems

Creator:: Stringham, Tamzen K.
Abstract:: Seasonal trends in water table level and soil moisture for four plant community types within an irrigated eastern Oregon riparian zone were described. Aboveground biomass, species composition, litter, percent bareground and percent basal cover of key plant species and life forms were measured. The relationship between water table levels and...

Metal and organic emissions from RDF and large volume contributor combustion

Creator:: Lee, Taejin, 1961-
Abstract:: The use of municipal refuse (RDF) as fuels has received widespread attention for reason of its energy equivalence and the increasing lack of available landfill sites. The principal obstacle to the construction of combustion facilities is that RDF produces toxic compounds, including heavy metals and such organic compounds as PCDD...
