The production and transportation of fuel from sawmill refuse is influenced by considerations of raw material cost, type of equipment, operating supplies, operating labor, and distance from source to market. Fuels from sawmill refuse are transported principally by means of trucks, railroad cars, barges, or combinations of those methods.
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...
Oregon Department of Environmental Quality (DEQ) permits for discharging seafood-processing wastes into adjacent estuarine waters expire July 31, 1974. Beyond this date, Oregon's seafood processors must adopt one or a combination of three options: curtailment of waste production, disposal outside of estuaries, or conversion of waste to some other product....
A series of stereo photographs displays a range of residue loadings for cleancut units in three general forest types common to coastal Oregon forest lands: Douglas-fir--western hemlock (second-growth), western hemlock--Sitka spruce, and red alder. Postburn residue levels are also represented for the Douglas-fir--western hemlock, and red alder types. Information with...
Pollution prevention is promoted by the Environmental Protection Agency (EPA) and other governmental agencies as a method of reducing the generation of wastes and pollutants. Pollution prevention is also called source reduction because it reduces wastes early in the production process. Source reduction has been used by some industries to...
The purpose of this study was to examine Oregon State University students' self-reported knowledge, attitudes, and behavior about recycling. Students living in on-campus and off-campus organized living groups were mailed a four-page survey with questions about their recycling activities, their attitudes about recycling, their opinions of the effectiveness of the...
The objectives of this study were to provide a comprehensive review of the risks and benefits of using adulticides to reduce risk of mosquito-borne disease (particularly West Nile Virus) transmission to humans, as well as to decrease annoyance from nuisance mosquitoes. The study was designed with two major research components,...
This report, Oregon pesticide use estimates for small fruits, 1990, is the first of five statewide pesticide use surveys covering: small fruits, tree fruits, seed crops and special crops, vegetable crops, as well as small grains, forage crops, and livestock. Oregon Pesticide Impact Assessment Program’s objective is to complete one...
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...
