Development And Recycling Of Novel Arsenic Removal Technology, Morgan Jones

Mahurin Honors College Capstone Experience/Thesis Projects

As of 2006, the U.S. Environmental Protection Agency (EPA) changed the Maximum Contaminant Level (MCL) for arsenic from 50 parts per billion (ppb), to 10ppb because of links to cancer. Current remediation technologies are expensive; therefore, this change will result in increased economic pressure on rural communities with high levels of arsenic in their drinking water. Lowering of the standard has spurred the development of a novel remediation technology that has shown the ability to reduce arsenic in drinking water at the source, with the added benefit of low-cost disposal of a stable and benign waste product in ordinary landfills. …

Factors That Influence The Distribution Of Antibiotic Resistant Bacteria In The Mud River, Wv, Timothy Shaun Dotson

Theses, Dissertations and Capstones

Background: Prior studies of the Ohio and Mud Rivers have shown that fecal contamination alone does not explain the distribution of antibiotic resistant bacteria (ARB) in surface waters. The objectives of this study were to determine effects on the distribution of ARB in the Mud.

Methods: Water samples and physical parameters were collected twice per season in spring through fall at 12 sites on the Mud River. Aliquots were plated on R2A agar and R2A agar plus individual antibiotics for the enumeration of total cultivable bacteria, and cultivable bacteria resistant to ciprofloxacin, virginiamycin, or tetracycline respectively. The IDEXX Quanti-Tray/2000™ method …

The Aridity Of Grace: Community And Ecofeminism In Barbara Kingsolver's Animal Dreams And Prodigal Summer, Richard M. Magee

English Faculty Publications

In both Animal Dreams and her later novel Prodigal Summer, Kingsolver constructs narratives of community inhabited by characters with a vivid awareness of the natural world and the threats to that world; furthermore, both novels feature strong female characters who long for a more harmonious life within nature. The novels develop and present forthright ecofeminist themes, with the women in the texts representing ideals of ecologically sensitive living who seek to educate their communities about threats to the environment and the defenses against those threats.

Kingsolver's ecofeminist vision, however, is frequently complicated and contradictory; just as the desert landscape …

Combination Of Natural Variability Estimation With Real Time Measurement For Mushroom Shelf Life Assessment., Leixuri Aguirre

Doctoral

The shelf life of mushrooms (Agaricus bisporus) is affected by the natural variability of the produce which influences the perishable vegetable quality. One of the main causes of this variability is non-homogeneity in the product maturity at harvest, resulting in each vegetable batch being at a different stage of senescence. The present work aims to study a new approach to improve the assessment of the shelf life of mushrooms (Agaricus bisporus) taking into account this variability. The study of variability involved the: i) study of the shelf life, quality parameters and variability of the mushrooms and modelling these experimental laboratory …

Ecotoxicological Investigations Of Pharmaceutical Compounds On A Battery Of Freshwater Test Species., Elaine Minagh

Masters

Currently interest in pharmaceuticals as potential environmental contaminants has increases significantly. This is due to the awareness of the possible adverse effects to human health and the environment caused by such contaminants. Within the past few years, the highly prescribed antidepressants, selective serotonin reuptake inhibitors (SSRI), have received attention as their occurrence in the environment has been recently documented. Prior to this, there was very little known about the ecotoxicity of SSRIs, and in particular sertraline hydrochloride. Similarly the cholesterol-lowering drugs, known as statins are among the most frequently prescribed agents in Ireland and worldwide for the treatment of coronary …

This presentation concludes by examining the issues and challenges that policy makers face when trying to implement …

Biodosepr-2006 Consensus Committee Report On Biodosimetric Methods To Evaluate Radiation Doses At Long Times After Exposure, Steven L. Simon, Ian Bailiff, André Bouville, Paola Fattibene, Ruth A. Kleinerman, David C. Lloyd, Stephen W.S. Mckeever, Alexander Romanyukha, Alexander V, Sevan’Kaev, James D. Tucker, Albrecht Wieser

Uniformed Services University of the Health Sciences

The requirements for biodosimetric techniques used at long times after exposure, i.e., 6 months to more than 50 years, are unique compared to the requirements for methods used for immediate dose estimation. In addition to the fundamental requirement that the assay measures a physical or biologic change that is proportional to the energy absorbed, the signal must be highly stable over time to enable reasonably precise determinations of the absorbed dose decades later. The primary uses of these biodosimetric methods have been to support long-term health risk (epidemiologic) studies or to support compensation (damage) claims. For these reasons, the methods …

Cell Cycle Analysis Of Atrazine-Treated Human Fibroblast Cells Using Flow Cytometry, Andrea L. Austin

Honors Program Theses

Atrazine is the most frequently used triazine herbicide in the United States. Studies have shown an association between herbicide exposure and increased levels of DNA damage, reproductive and endocrine problems, and an increased risk for certain cancers. The United States Environmental Protection Agency (USEP A) has set a maximum allowable limit at 3 parts per billion (ppb ). Previous work from our lab has shown decreased cell proliferation of normal human fibroblasts after low-level atrazine exposure for 72 hours at 0.8-100 ppb without a corresponding increase in apoptosis or necrosis.

The objective of the current study is to determine a …

Wastewater samples were collected from each of the abattoirs over three months period and examined for microbial content. Soil samples contaminated with the wastewaters were also collected and analyzed for microbial content as compared to soil without wastewater contamination in the neighborhood (control). Some physico-chemical parameters of the samples such as total dissolved solid, chemical oxygen demand, etc., were examined. The wastewater samples from both abattoirs were highly contaminated; Agege abattoir …

Writing On Water: Resources, Discourses, Reflections, Justin Scott-Coe, W. Scott Howard

Reconstruction: Studies in Contemporary Culture

[First paragraph]

We started this project in the shadow of the Great Tsunami of 2004, witnessed Katrina destroy New Orleans as submissions were coming in, and now publish during a record-breaking, nationwide—some say worldwide—heat wave. Is it any wonder the release of our journal issue on water appears as suspiciously timed as Al Gore's droning tome on global warming?

Smoking, Anemia, And Risk Of Oral Clefts In Utah, Melinda Michelle Moss

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cigarette smoke contains sufficient carbon monoxide to induce maternal and fetal hypoxia. Hypoxia is a known teratogen, and consequently maternal smoking has been the focus of many studies on adverse birth outcomes, including cleft lip and palate. Current literature of epidemiological studies on smoking and clefts suggests a modest but statistically significant increase in risk of clefting associated with maternal smoking. A biological condition that may also contribute to hypoxia is anemia. Data from the Utah Child and Family Health Study was used to assess the effects of hypoxia-inducing conditions, maternal smoking, anemia, and their interaction, on the risk of …

Science-Based Organic Farming 2006: Toward Local And Secure Food Systems, Charles A. Francis, Katja Koehler-Cole, Twyla Hansen, Peter Skelton

Publications from the Center for Applied Rural Innovation (CARI)

Organic farming includes growing food and fiber—animals, agronomic crops, horticultural fruits and vegetables, related products—as one dynamic and rapidly evolving component of our complex U.S. food system. Even as more farmers are moving toward organic certification and participation in an environmentally sound and economically lucrative market, questions arise about the long-term social impacts and sustainability of a set of practices that has gone from a movement to an industry. Consolidations in the organic trade have brought multinational corporations to the table, as they have observed a grassroots activity that has grown by 20% per year for the past two decades, …

Differential Expression Of Immune Response Genes In Steller Sea Lions (Eumetopias Jubatus): An Indicator Of Ecosystem Health?, Lizabeth Bowen, Brian Aldridge, Kimberlee Beckmen, Tom Gelatt, Lorrie Rea, Kathy Burek, Ken Pitcher, Jeffrey L. Stott

United States Department of Commerce: Staff Publications

Characterization of the polygenic and polymorphic features of the Steller sea lion major histocompatibility complex (MHC) provides an ideal window for evaluating immunologic vigor of the population and identifying emergence of new genotypes that reflect ecosystem pressures. MHC genotyping can be used to measure the potential immunologic vigor of a population. However, since ecosystem-induced changes to MHC genotype can be slow to emerge, measurement of differential expression of these genes can potentially provide real-time evidence of immunologic perturbations. MHC DRB genes were cloned and sequenced using peripheral blood mononuclear leukocytes derived from 10 Steller sea lions from southeast Alaska, Prince …

Cell Cycle Cyclin Expression Of Atrazine Treated Hepg2 Cells Using Western Blot Analysis, April Dawn Rand

Honors Program Theses

Atrazine is one of the most widely used herbicides in the United States. It is frequently used for general weed control on both industrial and agricultural land. However, atrazine has been associated with many harmful non-target effects in animals and humans. Due to its prevalence in the environment, the United States Environmental Protection Agency (USEP A) has set the maximal contaminant level of atrazine in drinking water at 3 ppb (USEP A, 2003 ). One of the non-target effects of atrazine is slowed growth of both normal and immortalized human cells. Previous work from our lab demonstrated that exposing normal …

The Effects Of The Herbicide Atrazine On Human Liver Cells, Erin R. Powell

Honors Program Theses

Atrazine is one of the most commonly used herbicides in the United States, in particular for maize crops. This herbicide is very effective against weeds. However, it has also been associated with many harmful health effects in non-target organisms such as amphibians and mammals. One of the non-target effects of atrazine may be to act as an endocrine disruptor in different cells. To study the endocrine system effects of atrazine in human cells, a human liver cell line (HepG2) was used. In this study, we determined the effects on growth of HepG2 cells after exposure to increasing concentrations of this …

The Role Of Peroxidases In The Development Of Plants And Their Responses To Abiotic Stresses., Deborah Vicuna

Doctoral

Peroxidases and its effects on plants were analysed. Peroxidases are involved in many physiological processes in plants, involving responses to biotic and abiotic stresses and the biosynthesis of lignin. Liglin is a polymer responsible for rendering the plant stronger and more rigid and also making the cell walls hydrophobic. Peroxidases are involved in the polymerization of the precursors of lignin. They are also involved in the scavenging of Reactive Oxygen Species (ROS), which are partially reduced forms of atmospheric oxygen, highly reactive, and capable of causing oxidative damage to the cell. Peroxidases can be a source of hydrogen peroxide (H2O2) …

Do Recent Data From The Seychelles Islands Alter The Conclusions Of The Nrc Report On The Toxicological Effects Of Methylmercury?, Alan H. Stern, Joseph L. Jacobson, Louise Ryan, Thomas A. Burke

Wayne State University Associated BioMed Central Scholarship

Abstract

In 2000, the National Research Council (NRC), an arm of the National Academy of Sciences, released a report entitled, "Toxicological Effects of Methylmercury." The overall conclusion of that report was that, at levels of exposure in some fish- and marine mammal-consuming communities (including those in the Faroe Islands and New Zealand), subtle but significant adverse effects on neuropsychological development were occurring as a result of in utero exposure. Since the release of that report, there has been continuing discussion of the public health relevance of current levels of exposure to Methylmercury. Much of this discussion has been linked to …
