The geochemical partitioning and bioavailability of trace metals in marine sediments

Creator:: Oakley, Stewart M.
Abstract:: Trace metals in the aquatic environment are generally concentrated on the surface of solid geochemical phases which eventually become incorporated into estuarine and marine sediments. The mechanism of trace metal concentration is believed to be adsorption with various geochemical phases such as hydrous metal oxides, clays, and organic matter. Metals...

Evaluating space use and pesticide exposure risk for burrowing owls in an agricultural environment

Creator:: Gervais, Jennifer A.
Abstract:: Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level...

Selenoprotein W : distribution and function in rat tissue and cultured cells

Creator:: Sun, Yu, 1963-
Abstract:: The objective of this study was to further determine the distribution of selenoprotein W (SeW) in tissues from rats and sheep fed different selenium levels and to search for the possible functions of this protein. In the rat study a total of 28 rat tissues were examined and SeW was...

Phenolic composition of red raspberry juice : influences of cultivar, processing and environmental factors

Creator:: Rommel, Angelika
Abstract:: Flavonols and ellagic acid compounds were characterized and measured in 55 experimental and commercial red raspberry juices by high performance liquid chromatography (HPLC) and diode array spectral techniques. Samples were prepared using Polyamide-6; a fraction eluted with methanol contained <_ 8 quercetin-glycosides, quercetin and kaempferol. Another fraction, eluted subsequently with...

Energy utilization by young grass carp fed different diets

Creator:: Cai, Zhengwei
Abstract:: Effects of diet on food energy utilization by grass carp fed aquatic plants or formulated diets with varied lipid sources and levels are presented in three manuscripts. Significant effects of diet on food consumption, digestion, growth and muscle fatty acid (FA) composition of fingerling diploid grass carp fed aquatic macrophytes...

Sublethal effects of estuarine carbaryl applications on juvenile English sole (Pleuronectes vetulus)

Creator:: Pozarycki, Scott V.
Abstract:: The pesticide carbaryl is applied annually to tidelands in Willapa Bay and Grays Harbor, WA to control populations of burrowing shrimp which modify sediments making the habitat unsuitable for oyster culture. Fish trapped on sprayed mudflats are often killed, but little is known about effects on fish present in subtidal...

Deposition and persistence of polynuclear aromatic hydrocarbons after slash burning clear-cut sites in Oregon

Creator:: Sullivan, Timothy Joseph
Abstract:: Research has been completed which identifies qualitatively and quantitatively the deposition, persistence and fate of polynuclear aromatic hydrocarbons (PNAH) on burned clear-cut sites in Oregon. Eight PNAH were identified and quantified in post-burn litter samples taken from four slash-burned sites. Deposition of lower molecular weight, 3-4 ring compounds was considerably...
