Effects Of Chemical And Mechanical Weathering Processes On The Degradation Of Plastic Debris On Marine Beaches, David A. Cooper
Effects Of Chemical And Mechanical Weathering Processes On The Degradation Of Plastic Debris On Marine Beaches, David A. Cooper
Electronic Thesis and Dissertation Repository
Plastics are an integral part of everyday life, and the use of plastic products for consumer goods, food packaging, recreational and commercial fishing and medical and sanitary applications continues to increase. The durability, low cost, light weight and hydrophobic nature of plastic make it a desirable material for numerous applications; however, these same characteristics make plastic debris in natural environments a pervasive problem. Increases in plastic use and low economic incentive for recovery, result in accumulation of debris in marine environments. Degradation of plastics through chemical weathering occurs in the open ocean or along shorelines where polymers are exposed to …
Lacking A Connection To A Community Water System: Water Quality And Human Health Impacts In El Paso Colonias, Yolanda Jane Mcdonald
Lacking A Connection To A Community Water System: Water Quality And Human Health Impacts In El Paso Colonias, Yolanda Jane Mcdonald
Open Access Theses & Dissertations
Water-borne disease and its symptoms, such as stomach cramps and diarrhea, are a serious concern in areas that are not connected to a public water system. To investigate the impacts of not being connected to a community water system, I surveyed households in El Paso County colonias that were not connected to a community water system (household n = 75, individual n= 293) and households that were connected to a community water system (household n = 75, individual n= 320). I conducted 150 door-to-door surveys and tested water samples from each household for free residual chlorine level, turbidity level, presence …
A Community-Based Participatory Assessment Of Fish Consumption And Dietary Mercury Exposure Along The Lower James River, Virginia Usa, Erica Lynnette Holloman
A Community-Based Participatory Assessment Of Fish Consumption And Dietary Mercury Exposure Along The Lower James River, Virginia Usa, Erica Lynnette Holloman
Dissertations, Theses, and Masters Projects
The use of community-based participatory research (CBPR) methods to conduct environmental exposure assessments provides valuable insight about disparities in fish consumption and contaminant exposure. Ninety-five community-specific fish consumption surveys were administered to low-income African American women (ages 16--49) residing in the Southeast community of Newport News, Virginia, USA, in 2008. The mean fish consumption rate for the women surveyed was 147.8 g/day (95% CI: 117.6-185.8), a rate substantially higher than the mean fish consumption rate reported for U.S. women (1.8 g/day 95% CI: 1.51-2.04). Through collaborative partnerships established between current researchers and The Moton Community House (a local community center), …
Sustainability Education As A Framework For Enhancing Environmental Stewardship In Young Leaders: An Intervention At Tryon Creek Nature Day Camp, Andrea Nicole Lawrence
Sustainability Education As A Framework For Enhancing Environmental Stewardship In Young Leaders: An Intervention At Tryon Creek Nature Day Camp, Andrea Nicole Lawrence
Dissertations and Theses
UNESCO established Sustainability Education as a top priority when it declared 2005 - 2014 to be the global decade for sustainability. Sustainability education can be implemented in outdoor programs such as nature summer camps in order to build environmental stewardship and ecological literacy in counselors and campers. This study sought to determine the extent to which an ecology and leadership training given to assistant counselors at Tryon Creek State Natural Area day camp achieved the goals of sustainability education--for the assistant counselors to learn about ecology, develop stewardship attitudes and behaviors toward the environment, and become positive role models for …
Water Quality Trading Markets For The Kentucky River Basin: A Point Source Profile, Ronald Childress Jr.
Water Quality Trading Markets For The Kentucky River Basin: A Point Source Profile, Ronald Childress Jr.
Theses and Dissertations--Agricultural Economics
This study assessed the feasibility and suitability of a Water Quality Trading (WQT) program within the Kentucky River Basin (KRB). The study’s focal point was based on five success factors of a WQT program: environmental suitability, geospatial orientation, participant availability, regulatory incentive, and economic incentive. The study utilized these five success factors, geographical characteristics, and Discharge Monitoring Reports (DMR) to assess the feasibility of a WQT program.
The assessment divided the KRB into five eight digit Hydrologic Unit Codes (HUC), North, Middle, and South Fork, Middle Basin, and Lower Basin, to determine regional impacts caused by the nutrient PSs. Individual …
