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 groundwater. In …

Investigation Of Toxic Chemicals In Plant-Based Milk Alternatives, Chukwunonso A. Anakwue

Dissertations (2016-Present)

Milk is a dietary component consumed all over the world and is known to be essential for development in children. Despite all the nutritional advantages associated with milk consumption, several issues like lactose intolerance, and high lipid content, etc., negatively affects the perception of cow milk consumption, and has grown into general health concerns. Issues with cow milk consumption drove for a healthier alternative and this led to plant-based milk alternatives (PBMA). Several studies have linked consumption of these PBMAs with other negative effects such as: allergy, poor nutrient profile and the presence of other foreign chemicals. This study’s main …

Providing Pesticide License Holders Ceu Credits During The Covid 19 Pandemic, Michael Wierda, Cody Zesiger, Jacob Hadfield, Micheal Pace, Paige Wray

Outcomes and Impact Quarterly

USU Extension and UDAF provide continuing education units (CEUs) for pesticide license renewal. However, in 2020, face-to-face meetings were canceled due to COVID-19. Workshop cancellation left CEU seekers with limited options. In response, programming was adapted and 2,992 CEU hours were provided via online sessions.

Fate Of Methoprene In Temperate Salt Marsh Ditches Following Aerial Applications, David J. Tonjes, Anne E. Mcelroy, Robin K. Barnes, Dominick V. Ninivaggi, Walter Dawydiak, Gregory T. Greene, Bruce J. Brownawell

Technology & Society Faculty Publications

Aerial applications of liquid methoprene are used in salt marshes to control mosquitoes by preventing adult emergence. Despite concern about toxicity to non-target organisms, little is known about environmental concentrations after applications, nor methoprene's persistence in salt marsh environments. Aqueous and sediment samples were collected from two marshes receiving weekly applications. Aqueous samples were collected as early as 30 minutes after applications and as long as nine days afterwards; sediment samples were taken within hours of application and as long as 19 days post-application. Use of time-of-flight liquid chromatography – mass spectral analysis allowed for ultra low detection limits (0.5 …

Justin's Save The Frogs Project, Justin Sather

The STEAM Journal

Justin’s Save the Frog Project goals are 1) to spread the awareness about the rapid decline in frog population 2) inspire others to make the environment a better place for people and animals 3) make an impact by building wetlands in California specifically for the CA Red-Legged Frogs and Foothill Yellow Legged.

Implementing A Community-Based Social Marketing Project To Improve Agricultural Worker Health, Joan D. Flocks, Leslie Clarke, Stan Albrecht, Carol Bryant, Paul Monaghan, Holly Baker

Joan D. Flocks

The Together for Agricultural Safety project is a community-based social marketing project working to reduce the adverse health effects of pesticide exposure among fernery and nursery workers in Florida. In 3 years, the collaboration between university and community researchers has embodied many of the principles of community-based research while completing multiple stages of formative data collection required for a social marketing project. This hybrid approach to developing a health intervention for a minority community has been successful in its early stages because the community partners are organized, empowered, and motivated to execute research activities with the assistance of academic partners. …

Pesticide Policy And Farmworker Health, Joan D. Flocks

Joan D. Flocks

Although data on the carcinogenicity of agricultural pesticides are still being generated and are thus incomplete, research such as the Agricultural Health Study indicates that populations with increased, regular exposure to pesticides have high rates of a variety of cancers (National Institutes of Health & Environmental Protection Agency 2008). Policies that regulate toxins such as pesticides are envisioned by the public to be empirical and objective, but toxins are socially produced and their regulation is just as often based on political and economic factors as it is on science (Luke 2000). This does not bode well for farm- workers who …

Prepubertal Organochlorine Pesticide Concentrations And Age Of Pubertal Onset Among Russian Boys, Thuy Lam, Paige Williams, Mary Lee, Susan Korrick, Linda Birnbaum, Jane Burns, Oleg Sergeyev, Boris Revich, Larisa Altshul, Donald Patterson, Wayman Turner, Russ Hauser

Mary M. Lee

BACKGROUND: In animal studies, organochlorine pesticide (OCP) exposure alters pubertal development; however, epidemiological data are limited and inconsistent. OBJECTIVE: To evaluate the associations of serum OCP concentrations [hexachlorobenzene (HCB), beta-hexachlorocyclohexane (beta-HCH), and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE)] with male pubertal onset. METHODS: In Chapaevsk, Russia, a town environmentally contaminated with OCPs, 350 8-9 year old boys with measured OCPs were enrolled during 2003-2005 and were followed annually for eight years. We evaluated three measures of pubertal onset: testicular volume (TV) > 3 mL in either testis, or stage 2 or greater for genitalia (G2+), or pubic hair (P2+). We used multivariable interval-censored models to …

ABSTRACT

Military Contamination And Persistent Organochlorine Pesticide Exposure Among Alaska Natives, Samuel Byrne

Legacy Theses & Dissertations (2009 - 2024)

St. Lawrence Island Alaska is located in the Bering Sea, only 36 miles from Siberia. The island is home to approximately 1600 Siberian Yupik residents, who rely heavily on subsistence hunting and gathering. There are two formerly used defense (FUD) sites on the island, one of which has been the subject of an approximate $110 million cleanup effort. Environmental monitoring suggests localized soil and watershed contamination with PCBs, organochlorine pesticides and heavy metals. Previous research suggests the site may be a source of PCB exposure for local residents. The primary aim of the study was to determine whether subsistence activities …

Effects Of Applied Soil Repellent Finish On Pesticide Residues In Work Clothing, Sandra L. Prior

Community & Environmental Health Theses & Dissertations

This study explores the feasibility of using an applied soil repellent finish, Scotchgard, on 100% cotton denim fabric in order to enhance the removal of atrazine and alachlor residue during the laundering process. The experimental findings provided no statistically significant evidence that Scotchgard fabric protector reduced pesticide residuals on the 100% cotton denim fabric either before or after laundering. A significant finding secondary to the study involved the possible interaction of Scotchgard with the pesticide alachlor, leaving greater amounts of residual on the fabric after laundering than those found with no fabric treatment. This suggests that agricultural workers be cautioned …
