Genetics and gene flow of organophosphate resistance in three predatory mites, Amblyseius andersoni Chant, Typhlodromus pyri Scheuten and Metaseiulus occidentalis Nesbitt (Acarina: Phytoseiidae), in Oregon

Creator:: Dunley, John E.
Abstract:: Genetics, gene flow, and distribution of pesticide resistance traits were examined for organophosphate (OP) resistance in three beneficial phytoseiid mites. Levels and genetics of OP resistance in Amblyseius andersoni were examined first. Laboratory strains from Italy and Oregon, USA, were compared in susceptibility to insecticides used in western Oregon fruit...

Isolation and identification of certain toxic compounds in a fraction of Kraft mill waste

Creator:: Wiman, Robert Edgar, 1933-
Resource Type:: Dissertation
Full Text:: FRACTION OF KRAFT MILL WASTE by ROBERT EDGAR WIMAN A THESIS submitted to OREGON STATE UNIVERSITY

An exploratory waste audit study of the Oregon automobile dealership industry to develop a "model" toxics use and hazardous waste reduction plan

Creator:: Wang, Mitchell K.
Abstract:: The move from hazardous waste management to pollution prevention is viewed as a paradigm shift in American industry. Pollution prevention involves source reduction to reduce the amount of hazardous waste that is generated, and recycling of those wastes that cannot be prevented within the production process. The first piece of...

Descriptive study of current practices of hazardous waste management among identified small quantity generators in Benton County

Creator:: Gebrewold, Fetene
Abstract:: Current evidence suggests that development and industrialization has engendered the manufacture and use of chemical products which may harm human health and degrade the environment. One of the most pressing environmental needs since World War II is perhaps the issue of how society either manages or mismanages hazardous wastes. The...

Multiple stressors and amphibian population declines

Creator:: Hatch, Audrey C.
Abstract:: In the past decade, declines in amphibian populations have captured scientific and popular interest. The causes of the declines are likely to be complex and involve interactions between several environmental stressors. Using multifactorial experiments, I investigated the combined effects of several anthropogenic stressors on developing amphibians in Oregon, USA. In...

Effects of pesticides on amphibians with special reference to the pyrethroidinsecticide, cypermethrin

Creator:: Biga, Lindsay M.
Abstract:: Pollution by pesticides is a ubiquitous concern for wildlife. The effects of pesticides are especially concerning in aquatic environments, which are particularly vulnerable as they have several exposure routes for the influx of chemicals. These effects are of particular concern as biodiversity loss reaches unprecedented rates. This includes recent declines...

Continuous monitoring and modeling to assess pesticide exposure in critical habitat for Pacific salmonids

Creator:: Janney, Philip K.
Abstract:: Pacific Northwest and California freshwater resources are key elements in the life history and ecology of Pacific salmon and steelhead listed as threatened or endangered under the Endangered Species Act. Risk to listed Pacific salmonid species can be assessed by evaluating the spatial and temporal co-occurrence of salmonid species at...

From pesticide degradation products to legacy toxicants and emerging contaminants : novel analytical methods, approaches, and modeling

Creator:: Forsberg, Norman D.
Abstract:: Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...
