Effects of pesticides on estuarine organisms : progress report : June 1, 1966 through July 31, 1969

Creator:: Millemann, Raymond E.
Abstract:: This report is largely concerned with the toxicity of Sevin (carbaryl) and Dursban (chlorpyrifos) on aquatic organisms. "The general objective of this research is to investigate the effects of various pesticides, which might be expected or are known to occur in estuaries, on the larval and adult stages of estuarine...

Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:: Sandahl, Jason
Abstract:: The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

Exposure and health risk assessment for farmers occupationally exposed to chlorpyrifos in Sri Lanka and drinking water and house dust analysis for chlorpyrifos

Creator:: Aponso, G. Lalith M.
Abstract:: This study was designed to assess chiorpyrifos exposure of a group of farmers by determining internal dose associated with a given application of this insecticide. This involved the monitoring of urinary levels of 3,5,6 trichloro-2-pyridinol (TCP), the major metabolite of chlorpyrifos. Incidental exposure was evaluated by determining the levels of...

Assessing the effectiveness and environmental impacts of using natural flocculants to manage turbidity

Creator:: Kegley, Laura J.
Abstract:: The objective of this research was to determine the feasibility of using chitosan as a natural flocculant to control turbidity during in-stream construction work. A series of field tests in Oak Creek, Corvallis, OR were conducted in order to test the effectiveness for turbidity control and the environmental impacts of...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

Factors influencing residual stand damage levels due to cable thinning of coniferous stands in western Oregon

Creator:: Caccavano, Michael P.
Abstract:: The purpose of this study was to determine the significant variables influencing the damage levels sustained by the residual stand after skyline thinning of coniferous stands. Damage levels were measured in ten study areas in western Oregon that had received their first commercial thinning. For this post-logging study, 38 units...

The effect of ration formulation on the subsequent generation of volatile gases and odors from bovine waste

Creator:: Kellems, Richard O.
Abstract:: The objective of this study was to determine the effect that ration formulation has on volatilization of gases and offensiveness of the odor associated with the wastes produced from Holstein replacement heifers. Six separate experiments were conducted to study the relationships between different variables on the release of hydrogen sulfide,...

The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

Creator:: Harris, James O.
Abstract:: The use of terbacil for weed control was adapted by a high percentage of Oregon peppermint growers soon after its introduction in 1967. To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...
