Noise pollution is a growing concern in the environmental health community. Unlike other common exposures, such as air and water pollution, noise is uniquely difficult for an individual to protect themselves from. Studies have shown multiple adverse health outcomes resulting from exposure to noise pollution, including hearing impairment, negative social behavior and annoyance, sleep disturbance, along with a strong association between noise pollution and high cardiovascular risk. It is important, then, to look for solutions to this exposure. This study is designed to assess the effects of a tree barrier in reducing traffic noise. Noise monitoring was conducted at Saint …

The Improvement Of The Regional Regulatory Governance System For Radiation Risk Management: Spatial Analysis On Radiation Hazards In South Korea, Sangwon Lee, Jaewon Lim, Chan Goo Yi
Public Policy and Leadership Faculty Research
Since the 2011 Fukushima nuclear power plant accident, nuclear regulators have strength-ened safety standards or decided to decommission the nuclear power plant. The vast majority of radiation is from nuclear power plants, so safety measures are also concentrated in nuclear power plants. Radioactive materials located much closer to the people are scattered around the nation. However, it is difficult for citizens to predict the radiation risk around them because regulatory agencies do not provide adequate information on radiation. The main goal of this study is to analyze the spatial distribution patterns of radioactive materials that serve as indicators for potential …

Developing High-Resolution Meteorological Datasets To Assess The Short-Term Association Between Meteorological Factors And Green Space And Mental Disorders, Xinlei Deng
Legacy Theses & Dissertations (2009 - 2024)
Global climate change is linked to the frequency and intensity of local climate extremes such as heatwaves, cold spells, and flooding. Scientific evidence indicates that heatwaves and higher ambient temperature could increase the risk of hospital admission and emergency department (ED) visits for mental disorders (MDs). On the other hand, urban green space is considered a way to reduce heat island effects and provide comfort for area residents. However, there still exist huge research gaps. Except for temperature, few studies have examined how other meteorological factors (relative humidity (RH), solar radiation (SR), heat index (HI), and rainfall) are associated with …

Biomimetic properties of endocrine disrupting compounds (EDC) enable these chemicals to induce physiological responses in organisms at the cellular level, affecting fishes, amphibians, reptiles, birds, and mammals. Perchlorate is a ubiquitous EDC to which nearly all humans of industrialized countries are exposed. Perchlorate competitively inhibits the sodium-iodide symporters located within the follicular cells of the thyroid gland, reducing the body’s ability to uptake iodide and synthesize thyroid hormone (TH), a crucial hormone in the regulation of many metabolic processes. Threespine stickleback (Gasterosteus aculeatus) and zebrafish (Danio rerio) are aquatic model organisms used in perchlorate exposure research. Exposure causes many common …

Pfas Environmental Contamination In Central Maine, Megan H. Andersen
Honors Theses
PFAS (per- and polyfluoroalkyl substances) are toxic, persistent, and bioaccumulative chemicals that are used in a variety of consumer products and industrial applications. Paper mills across the state of Maine have used PFAS in their industrial paper making processes, and their wastes often flow for treatment into municipal sewage treatment facilities. PFAS contaminated municipal wastewater from the general use of PFAS consumer products are also processed by these plants. Liquid waste is condensed into solid waste septage and sludge, and in what was thought to be an environmentally friendly repurposing practice, municipal sludge and septage has been spread on plots …

It Permeated Everything: A Lived Experience Of Slow Violence And Toxicological Disaster, Tara Jo Holmberg
Antioch University Dissertations & Theses
Impacts of disasters on individuals are dependent on numerous factors: local to international political dynamics, socioeconomics, geography, educational background, and outside support among others. Currently, much of disaster research focuses on those of natural origin, acute and large-scale environmental events, emergency management, and the ability of individuals, communities, and societies to prepare for, and recover from, likely known disasters in their region. However, there is a lack of data about individual experiences through ‘invisible’ anthropogenic disasters, especially those that fall under the umbrella of slow environmental violence (Davies, 2019; Rice, 2016). Through critical phenomenological autoethnography, I examine an individual experience …

Ammonia Cycling And Emerging Particulate Matter Pollutants Under Arable Land-Use Management: A Modelling Approach, Vivien Pohl
Doctoral
Air quality monitoring in Ireland is under the jurisdiction of the Environmental Protection Agency in compliance with the Gothenburg Protocol, EU/national legislation, and the National Clean Air Strategy. Particulate Matter (PM) has been acknowledged as a key atmospheric pollutant, with serious public health impacts and no safe threshold of exposure in place to-date. Ammonia (NH3) emissions are linked to the secondary production of PM through atmospheric reactions occurring with acidic atmospheric components such as sulfuric acid, nitric acid, and hydrochloric acid. These reactions result in the formation of ammonium sulfate, ammonium nitrate and ammonium chloride, among others. More than 95% …

Longitudinal Patterns Of Microplastic Abundance And Potential For Food Web Uptake In The Yakima River, Janell Shah
All Master's Theses
Microplastic (MP) pollutes environments worldwide, but the ecological consequences remain largely unknown. While MP research has historically focused on marine environments, recent work has increasingly investigated rivers as transporters of MP from terrestrial sources to the ocean. Some studies have documented instances of MP consumption in a river food web, but few have investigated multiple consumers at different points along a river continuum. This study enumerated the MP abundance in the water column, biofilm, and four macroinvertebrate families from different functional feeding groups across nine sites spanning 344 kilometers from the headwaters to the mouth of the Yakima River in …
