Dibutyl Amine Detection, Quantification, And Removal With Iron(Ii)Tetrasulfophthalocyanine (Fetspc), Kyle Bittner

Electronic Theses and Dissertations

Pesticide testing is of practical interest in various areas of today’s world due to their prevalence and toxicity. These areas include agriculture, environmental, chemical plants, and many others. Herbicides, like Roundup, contain secondary amines such as glyphosate. The ability to detect secondary amines could offer a method for glyphosate detection in agricultural and environmental samples. Secondary amines can interact with metal complexes through electron charge transfer. Such interactions can cause a change in the metal’s electron configuration and energy state and can be seen in the UV-Vis spectrum. Metal phthalocyanines (MPc’s) and other organometallic complexes have been ...

Atrazine Levels In Rural Nebraska Counties And Parkinson's Disease, Muhammad Zahid 2022 University of Nebraska Medical Center

Atrazine Levels In Rural Nebraska Counties And Parkinson's Disease, Muhammad Zahid

Capstone Experience

Parkinson's disease (PD) is a multifactorial disorder, connecting both genetic susceptibility and environmental risk factors. Several epidemiological and experimental studies support the evidence that pesticides exposure is positively associated with enhancing neurodegenerative diseases. The high amount of atrazine used in Nebraska and increased PD cases led us to evaluate the association between the long-lived water-soluble pesticide atrazine and PD in Nebraska counties. A person's exposure to atrazine may come from inhalation, dermal absorption, and ingestion. Three types of atrazine data covering 1992 to 2017 were used for this study: applied atrazine, atrazine in surface water, and atrazine in ...

Towards The Determination Of Estrone And 17Β-Estradiol In Dairy Cattle Waste Using Solid Phase And Stir Bar Sorptive Extractions With Liquid Chromatography-Mass Spectrometry And Gas Chromatography-Mass Spectrometry, Pallavi Ragi

Masters Theses & Specialist Projects

Steroidal hormones are naturally produced as a part of many physiological processes and are excreted in the urine and feces of animals and humans. Farm animals in concentrated animal feeding operations (CAFOs) are routinely implanted with synthetic and natural hormones to enhance growth and production, contributing significantly to environmental steroid hormone contamination. Every year around 49 tons of estrogens are generated by livestock waste in the United States alone. Due to rainfall and runoff, these steroid hormones reach the environment when animal waste is applied as manure. Studies show that estrogens and other steroidal hormones present in the surface waters ...

Barriers To Public Health In Latino American Indigenous Communities, Wilzave Quiles Guzman 2022 St. Mary's University

Barriers To Public Health In Latino American Indigenous Communities, Wilzave Quiles Guzman

St. Mary's University Honors Theses and Projects

This paper focuses on barriers to public health in Latino American Indigenous communities. Indigenous people throughout the world are at a public health disadvantage due to a lack of clearly defined practices within the decision-making processes to plan, evaluate, and control finances from governmental and non-governmental entities in charge of managing health services. I argue that political, social, and institutional changes are still needed to achieve health equity in Indigenous communities and that these changes should go beyond implementing a universal health care program. I must recognize improvements made by many Latino American countries like Brazil, which prepared a plan ...

Aeromonas Phage Research And The Public Health Impact Of Antibiotics In Aquaculture Workers, Madelyn Merchant 2022 Bowling Green State University

Aeromonas Phage Research And The Public Health Impact Of Antibiotics In Aquaculture Workers, Madelyn Merchant

Honors Projects

One of the most common fish diseases in aquaculture is Aeromonas infection. The most common way to treat this infection is through antibiotics. The bacteria in the fish can become antibiotic-resistant and perpetuate the disease. The diseases in fish create a huge financial loss and the industry loses $6 billion per year due to diseases in fish. An alternative to antibiotics is bacteriophage which causes less environmental degradation and is better for human gut flora. In aquaculture there have been examples of aquaculture workers becoming sick from the water in aquaculture ponds as well as from people eating the fish ...

Accumulation Of Persistent Organic Pollutants In Marine Mammals: A Case Study On Cetaceans, Pinnipeds, And Sirenians, Alydia Moorhead

All HCAS Student Capstones, Theses, and Dissertations

Persistent organic pollutants (POPs) are lipophilic semi-volatile organic chemicals that present a range of challenges to marine biota, specifically marine mammals that often occupy a high trophic position in the food web. POPs have become a global problem since they have been shown to cause immunologic, teratogenic, carcinogenic, neurological, and reproductive complications in living organisms due to their resistance to biodegradation and their lipophilic nature. Marine mammals can accumulate these toxic substances through direct ingestion, trophic transfer, adsorption, and maternal offloading. They are susceptible to both bioaccumulation and biomagnification of POPs. Accumulation of POPs is affected by many variables, including ...


Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood 2022 Bowling Green State University

Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood

Honors Projects

Global lakes are experiencing an increase in toxic algal blooms that can be damaging to the environment. These blooms are caused by cyanobacteria, specifically a species called Planktothrix. Skinn Lake, in Ohio, is a location of a cyanobacterial bloom that is mainly populated by Planktothrix rubescens. This lake was further examined to identify the major toxin-producing bacteria and identify environmental microbes surrounding the bloom. When the data was examined it was found that the microbiomes of the lake greatly differed between the winter (bloom) months and the summer (non-bloom) months. This difference can be viewed within the nutrient analysis from ...
