Disability In An American Indian Community : Prevalence, Distribution, And The Role Of Polychlorinated Biphenyls, Thoin F. Begum
Disability In An American Indian Community : Prevalence, Distribution, And The Role Of Polychlorinated Biphenyls, Thoin F. Begum
Legacy Theses & Dissertations (2009 - 2024)
Phthalates have been implicated as reproductive toxicants in animal models and in human populations. This study examined associations between potential exposure sources and urinary phthalate concentrations among couples undergoing infertility treatment. Women (n=56) and their male partners (n=43) undergoing in vitro fertilization (IVF) were enrolled in a prospective cohort investigation of environmental chemicals and IVF outcomes at an academic medical center. On the day of oocyte retrieval, participants provided urine samples and completed questionnaires detailing use of personal care products (PCPs), and consumption of medications, foods, and beverages in the preceding 24-hours. Urine was analyzed for MEP, MBP, MPP, MHxP, …

The Akwesasne reservation along the St. Lawrence River has experienced significant exposure to several persistent organic pollutants due to rapid industrialization. The Aluminum Company of America, General Motors, and Reynolds Metals operated aluminum foundries that used polychlorinated biphenyls (PCBs) as hydraulic fluids, which contaminated the community environment, the soil, air and water, and community food sources with PCBs. We administered the World Health Organization Disability Assessment Schedule II (WHODAS II) to 119 Akwesasne Mohawk adults residing along the St. Lawrence River in New York. We used exploratory factor analysis to summarize the 36- items comprising the WHODAS II. The 7 …
Public Perception Of Air Quality Risks In Portland, Oregon, Dawn Nolan
Public Perception Of Air Quality Risks In Portland, Oregon, Dawn Nolan
Dissertations and Theses
The availability and demand for localized air quality information from communities are on the rise. However, not all information and not all communities are the same. Effective engagement and communication strategies will depend on a community's existing knowledge, opinion about air quality, individual experiences with inequities, and more. This study aims to understand how people living in Portland, Oregon understand and experience air pollution as an environmental risk and examine the extent to which those risk perceptions relate to confidence in science and technology. This gap is critical because of the complex interaction between air pollution and the risk perception …
Nanocarbon Modification Of Membranes For Enhanced Water Desalination And Water Treatment, Worawit Intrchom
Nanocarbon Modification Of Membranes For Enhanced Water Desalination And Water Treatment, Worawit Intrchom
Dissertations
Water scarcity is foreseen to be one of the great global issues in the coming decades. The challenges are not only in providing water supply to cope with the growing public demand, but recovering clean water to natural resources. Clean water supply, from brackish and seawater is attractive. Membrane distillation (MD) is an emerging thermal membrane-based process that has been used for desalination and other pollutant separations from water. MD can be operated at low temperature, so low-grade energy sources are a good alternative heat source for MD. High salt rejection and low membrane fouling also make MD interesting for …
Detection Of Pahs In Commercial And Wild Caught Fish Oil Using Scanning Fluorescence Spectroscopy, Edwin Antonio Pena
Detection Of Pahs In Commercial And Wild Caught Fish Oil Using Scanning Fluorescence Spectroscopy, Edwin Antonio Pena
Seton Hall University Dissertations and Theses (ETDs)
The DeepWater Horizon (DWH) oil spill contaminated a large area in the Gulf of Mexico in summer 2010. It is likely that many aquatic species in the Gulf were affected by the spill. Crude oil contains polycyclic aromatic hydrocarbon (PAHs). Some PAHs are carcinogenic to fish and humans. The purpose of this project was to develop menhaden fish oil as a biomonitoring tool for crude oil contaminants such as PAHs using scanning fluorescence spectroscopy (SFS). Menhaden (Genus Brevoortia) is one of the most ecologically and economically important marine fish species along the Atlantic and Gulf coast; however, it is …
Nitrogen Fixation In Arid Western Soils, Robert Charles Rychert
Nitrogen Fixation In Arid Western Soils, Robert Charles Rychert
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nitrogen fixation by blue-green algae-lichen crusts from South Curlew Valley, Utah, in the Great Basin Desert, was studied using the acetylene reduction technique. A molar ratio of 3 moles C2H4 produced/mole of N2 fixed was used to estimate nitrogen (N2) fixation by acetylene reduction. Nostoc was found to be present in many of the lichen thalli examined microscopically. Crust nitrogen fixation decreased rapidly below -1/3 bar pressure (water potential) which indicated that nitrogen fixation occurs only when the crust is wet. This would suggest that most of the crust nitrogen fixation in the Great …
