Advancing Understanding Of Knowledge's Role In Lay Risk Perception, Branden B. Johnson Jun 1993

Advancing Understanding Of Knowledge's Role In Lay Risk Perception, Branden B. Johnson

RISK: Health, Safety & Environment (1990-2002)

Emphasizing how knowledge affects lay Risk perception, summarizing studies and suggesting further research, the author differentiates between knowledge production, knowledge dissemination and information processing as affected by, e.g., heuristics and Risk aversion. He also suggests that better understanding of lay knowledge can also illuminate experts' hazard knowledge.

Computer Simulation Model Calibration And Validation For Prediction Of Water Quality Impacts Of Poultry Waste Disposal, D. R. Edwards, T. C. Daniel Jun 1993

Computer Simulation Model Calibration And Validation For Prediction Of Water Quality Impacts Of Poultry Waste Disposal, D. R. Edwards, T. C. Daniel

Arkansas Water Resources Center Technical Reports

Runoff and water quality data collected from two pairs of grazed fields in northwestern Arkansas were analyzed to support efforts to model runoff quality from areas receiving poultry manure and other fertilizer sources. The monitoring period described in this report was September 1, 1991 to April 30, 1993. One of each pair of fields was fertilized with inorganic fertilizer, and the other received either poultry litter or manure. Losses of fertilizer constituents were quite low from an agronomic standpoint, ranging from approximately 2-11 kg N/ha/year and 0.5-4.1 kg P04-P/ha/year. Annual losses of fertilizer constituents were dominated by only a small …


Comparison Of Predicted And Observed Dioxin Levels In Fish: Implications For Risk Assessment, Judy S. Lakind, Daniel Q. Naiman Jun 1993

Comparison Of Predicted And Observed Dioxin Levels In Fish: Implications For Risk Assessment, Judy S. Lakind, Daniel Q. Naiman

RISK: Health, Safety & Environment (1990-2002)

After comparing sampled and modelled dioxin levels in the tissue of fish near pulp and paper mill discharges, the authors argue that, until an improved bioaccumulation model is incorporated into EPA's Risk assessment process, determination of human health Risks associated with consuming dioxin-contaminated fish should be based on sampling.

The Effects Of Composting Of Yard Wastes On The Ground-Water Quality: Wmu Farms Site, Kalamazoo, Michigan, Bryan Kirk Allen Jun 1993

The Effects Of Composting Of Yard Wastes On The Ground-Water Quality: Wmu Farms Site, Kalamazoo, Michigan, Bryan Kirk Allen

Masters Theses

In the rush to find alternatives to landfilling of yard waste, federal and state agencies have identified composting as the main solution. There is therefore a need to address the possible environmental problems which could be associated with such composting operations. Compost may contain nutrients, organic acids, pesticides, and metals which could leach through soils to the ground water posing a potential contamination problem.

At the WMU Farms Site, two sites have been used for the composting of leaves by the City of Kalamazoo. The physical and chemical hydrogeology of these sites were characterized.

The results suggest that the presence …

Mixed Culture Biodegradation Of Pentachlorophenol, Hexachlorobenzene, And Tetrachloromethane Under Anaerobic Conditions, Jesse Zahn May 1993

Mixed Culture Biodegradation Of Pentachlorophenol, Hexachlorobenzene, And Tetrachloromethane Under Anaerobic Conditions, Jesse Zahn

Theses

Three chlorinated compounds, namely, Pentachlorophenol(PCP), Hexachlorobenzene (HCB), and Carbon tetrachloride were biodegraded under anaerobic conditions using a (CCl4)mixed culture obtained from an anaerobic sewage sludge digestor in Linden, NJ.

Three sets of cultures capable of degrading each of the target compounds were established. Primary Enrichment Cultures (PECs) from the anaerobic sludge were exposed to each one of the target compounds. The cultures were able to degrade each target compound as follows: HCB, 0 to 1.2 ppm; PCP from 0 to 3-4 PPM; CCl4, 0.5 to 15.5 PPM

One culture from each PEC group (CCl4, …

Problem Analysis For The Vegetation Diversity Project, David A. Pyke, Michael M. Borman, U.S. Department Of The Interior, Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

Management of the majority of public rangeland in the Great Basin and Columbia-Snake River Plateau falls under the authority of the Bureau of Land Management. The flora of this land ranges from highly diverse native plant communities to deteriorated lands dominated by exotic annuals. Approximately nine percent of the BLM’s 78 million acres of public land in this region is degraded to such a degree that changes in land management alone will not result in significant improvement. The BLM intends to restore native plant communities on these deteriorated lands, but current revegetation techniques used to establish introduced perennial grasses are …

Land Use Patterns In Relation To Lake Water Quality In The Salmon Lake Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby College

Colby College Watershed Study: Salmon Lake and McGrath Pond (2009, 1993)

Salmon Lake has a history of algal blooms which have decreased the recreational and aesthetic value of the lake (Nichols et al. 1984). As early as the 1920’s, Salmon Lake was reported to have poor water quality. Algal blooms were reported throughout the 1970’s. Numerous complaints led to a study in 1975 by the Maine Department of Environmental Protection (MDEP) and another in 1984 by the U.S. Geological Survey to determine the cause of the accelerated algal growth in the ponds. Both studies concluded that the primary cause of these algal blooms was high concentrations of phosphorus in the water. …


Saving The Catchments Of Albany's Harbours, Ashley Prout Jan 1993

Saving The Catchments Of Albany's Harbours, Ashley Prout

Journal of the Department of Agriculture, Western Australia, Series 4

Fertiliser, particularly phosphorus, running off farm land is a major source of nutrient entering Albany's harbours. Oyster Harbour, which has a large rural catchment, is especially at risk.

The build-up in nutrients in the harbours has caused nuisance algal growth since the early 1970s and subseuent death of more than half the seagrass beds, which are vital to the areas marine life.

The Department of Agriculture, at the request of the Environmental protection Authority, has developed and promoted catchment management plans that enable rural land holders to reduce the amount of run-off into the harbours without necessarily sacrificing farm productivity. …

Canyonlands National Park And Orange Cliffs Unit Of Glen Canyon National Recreation Area Environmental Assessment For Backcountry Management Plan, National Park Service Jan 1993

Canyonlands National Park And Orange Cliffs Unit Of Glen Canyon National Recreation Area Environmental Assessment For Backcountry Management Plan, National Park Service

All U.S. Government Documents (Utah Regional Depository)

Whether on foot, bicycle, horseback, or in vehicles, most visitors come to Canyonlands National Park (Canyonlands) to experience solitude or to "get away from people." Yet visitation to Canyonlands has risen exponentially over the past five years (Figures 1 and 2). Visitation is expected to continue to rise. As a function of this increase in number of visitors, adverse impacts to Canyonlands' resources have increased and the visitors' ability to find solitude has decreased. Since the mandate of the National Park Service (NPS) is to balance visitor access to the parks with preservation and protection of natural and cultural resources, …
