Ecowomanism: A Solution To Climate And Social Injustice, Alexis K. Karon

Religion: Student Scholarship & Creative Works

The interconnections of climate justice and social inequalities are paired together in a concept named 'Ecowomanism'. Originally inspired by Melanie L. Harris, ecowomanism uses spiritual theologies, experiences, and memories to discuss the post-modern struggles that women of African and indigenous descent face in society, which can then find solutions to such injustices in a reconnection to nature. In this paper, I argue that adopting an environmental paradigm inspired by the spiritual theology of ecowomanism in the United States, which acknowledges the connection between oppression and violence against communities of color to the violence and domination of the environment, a more …

A Geostatistical Study Of Socioeconomic Status (Ses), Rurality, Seasonality And Index Test Results As Drivers Of Free Private Groundwater Testing In Southern Ontario, 2012–2016, Shahryar Qayyum, Paul Hynds, Harriet Richardson, Kevin Mcdermott, Anna Majury

Articles

Approximately 12% of the Canadian population uses private wells for daily water consumption; however, well water testing rates are on the decline, resulting in an increased risk of waterborne acute gastrointestinal illness. To date, limited research has explored the determinants influencing well testing practices. Accordingly, the current study sought to investigate the drivers of “one-off” and repeat well water testing in southern Ontario during the 5-year period 2012–2016, using the worlds largest private groundwater testing data-frame. Data from >400,000 wells were geospatially integrated with all tests conducted by the provincial laboratory in southern Ontario. The Ontario Marginalization Index (ON-Marg) was …

Sources And Toxicity Of Mercury In The San Francisco Bay Area, Spanning California And Beyond., Mietek Kolipinski, Mani Subramanian, Kristina Kristen, Steven Borish, Stacy Ditta

Natural Sciences and Mathematics | Faculty Scholarship

This report synthesizes and evaluates published scientific literature on the environmental occurrence and biomagnification of mercury with emphasis on the San Francisco Bay Area (SFBA), California. Mercury forms various compounds, well known for their toxicity in humans and environmental ecosystems. Elemental mercury is transported and distributed by air, water, and sediments. Through the metabolic processes of algae and bacteria, mercury is converted into organic compounds, such as methylmercury (MeHg), which then bioaccumulates up through trophic levels. In fish, it is found primarily in skeletal muscle, while in humans, the primary target organs are the brain and kidneys. Health concerns exist …

Remaking Environmental Justice, Clifford Villa

Faculty Scholarship

From movements for civil rights in the 1960s and environmental protection in the 1970s, the environmental justice movement emerged in the 1980s and 1990s to highlight the disparate impacts of pollution, principally upon people of color and low-income communities. Over time, the scope of environmental justice expanded to address concerns for other dimensions of diversity. New and continuing challenges tell us that we need to reframe our understanding of environmental justice to ensure better protection for people going forward. One way to reframe this understanding may be to apply the heuristic of vulnerability analysis as proposed by legal theorist Martha …

An Exploration Of Zero Waste Policies And Recommendations For Missoula, Sarah Blyth Lundquist

Graduate Student Theses, Dissertations, & Professional Papers

“Zero Waste” is a concept and community goal that has arisen to challenge the current consumerist economic system and offer solutions for a number of environmental issues. In adopting this goal, individuals and communities pledge to reduce and divert at least 90% of their waste in a certain number of years. These goals can be reached by employing policies, programs, and other intervention tactics which establish Zero Waste infrastructure, ensure equitable and widespread access to Zero Waste services, and provide educational outreach and resources to the community. Missoula adopted a Zero Waste goal in 2016 and created a Zero Waste …

Collecting Plant Phenology Data In Imperiled Oregon White Oak Ecosystems: Analysis And Recommendations For Metro, Kirsten Wright

Environmental Science and Management Professional Master's Project Reports

Imperiled Oregon white oak ecosystems are a regional conservation priority due to the rich biodiversity they support, including rare and endemic species such as Oregon state-listed endangered pale larkspur (Delphinium leucophaeum). Previously dominant in the Pacific Northwest, upland prairie and oak woodlands are now under significant threat, with only 2% remaining in the Willamette Valley in small fragments.

Over the past 150 years, conversion to agriculture, urban development and fire suppression have dramatically reduced and degraded Oregon white oak habitat. Climate change has now emerged as an additional threat, causing observable shifts in plant phenology. In fragile oak …

A rapidly changing Arctic as a result of climate change and ice loss is rendering the North more accessible, providing new opportunities while producing impacts on the Arctic. …

Knowledge And Behavioural Interventions To Reduce Human Health Risk From Private Groundwater Systems: A Global Review And Pooled Analysis Based On Development Status, S. Mooney, C. P. Mcdowell, J. O'Dwyer, P. D. Hynds

Articles

Groundwater contamination constitutes a significant health risk for private well users residing in rural areas. As the responsibility to safeguard rural private domestic groundwater typically rests with non-expert homeowners, interventions promoting risk mitigation and awareness represent the most viable means of preventing supply contamination. However, no global review or pooled analyses of these interventions has been undertaken to date. The current study sought to identify and quantify the performance of private well interventions from 1990 to 2018 via a global systematised review and pooled analysis. The PICO (Population-Intervention-Comparison-Outcome) approach was employed for literature identification. Relevant studies were statistically analysed across …

Risk Communication Approaches For Preventing Private Groundwater Contamination In The Republic Of Ireland: A Mixed-Methods Study Of Multidisciplinary Expert Opinion, S. Mooney, J. O'Dwyer, Paul Hynds

Articles

The mechanisms of private-well groundwater contamination are uniquely complex, necessitating a multisector communicative approach to risk management, premised on behaviour promotion. In countries such as the Republic of Ireland (ROI), characterised by oftentimes high groundwater contamination risk and concurrently limited user awareness, incorporation of multidisciplinary, ‘expert-based’ knowledge may facilitate design of evidence-based, practical interventions. Expert interviews represent an efficient form of expert consultation, enabling ease of access to niche information and comparison of procedure, but remain under-utilised within the groundwater management literature. In response, the current study elicited opinion from 50 experts across four broad categories (communications, engineering/science, policy, and …

Plastics Derived From Derelict Fishing Gear In The Arctic: Looking At Sustainable Fisheries For A Strategy Of Mitigation, Remediation And Prevention In Iceland And Alaska, Natalie S. Armstrong

Pitzer Senior Theses

Marine plastics are not just a problem, they are a silent, sinister epidemic. Marine plastics are the largest economic and ecological threat to our marine ecosystems, particularly marine plastics derived from lost and or discarded fishing gear, which affects sensitive marine communities, the chemical composition of the ocean water, and the physical makeup of the seafloor. With 6.4 million tons of marine debris entering our oceans annually, a third of which is lost fishing gear, it is estimated that, by weight, in 2050 there will be an accumulation of more plastic than fish in the ocean (Heath, 2018; Wilcox, 2015). …

A Modeling Approach To Understanding Glyphosate Transport In The Belize River Watershed, Barbara Anmei Astmann

Theses and Dissertations--Civil Engineering

Glyphosate is the most widely used herbicide worldwide and is often transported from application areas to surface water when solubilized in runoff or sorbed to eroded sediment. There is evidence that suggests both glyphosate and its main metabolite aminomethylphosphonic acid (AMPA) may pose a risk to human health, as well as cause adverse effects in the environment. However, consistent monitoring data is still limited, especially in developing countries. Belize is a developing nation with agriculture being a major sector of its economy and is heavily reliant on glyphosate. The widespread use of glyphosate in Belize may be resulting in glyphosate …

Dissipation Of Pesticide Residues On Grapes And Strawberries Using Plasma-Activated Water, Chaitanya Sarangapani, Laurence Scally, Miroslav Gulan, P. J. Cullen

Articles

In this study, we present a novel atmospheric air plasma discharge for the generation of plasma-activated water (PAW), with the aim of reducing pesticide residues on fresh fruit. For this purpose, a large discharge volume pin-to-plate cold plasma reactor was employed. The pesticide-spiked grapes and strawberries were processed with varying PAW concentrations to study their efficacies for pesticide degradation combined with an evaluation of any induced changes in key nutritional and quality attributes. The results suggest that the reduction of chlorpyrifos was 79% on grapes and 69% on strawberries while that of carbaryl was 86% on grapes and 73% on …

Adaptive Background Correction Of Crystal Image Datasets: Towards Automated Process Control, Luke Kiernan, Ian Jones, Lauri Kurki, Patrick J. Cullen, Toufic El Arnaout

Articles

Improving the data descriptor calculation of crystal’s physical properties requires sophisticated imaging techniques and algorithms. It has been possible to construct 2D population balance models benefiting from characteristic measurements of both crystal’s length and width, compared to the single representative sizes used in 1D models. Our aim is to ameliorate the procedure of determining shape (and not only size) factors, in an automated fashion and directly from the process, for implementation in future models. Here, approaches suitable for real-time applications were employed including engineered imaging sensors and adaptive algorithms. We described the latter in detail for varying 2D image datasets. …

Enhancing Models And Measurements Of Traffic-Related Air Pollutants For Health Studies Using Dispersion Modeling And Bayesian Data Fusion, Stuart A. Batterman, Veronica J. Berrocal, Chad Milando, Owais Gilani, Saravanan Arunachalam, K. Max Zhang

Faculty Journal Articles

Research Report 202 describes a study led by Dr. Stuart Batterman at the University of Michigan, Ann Arbor and colleagues. The investigators evaluated the ability to predict traffic-related air pollution using a variety of methods and models, including a line source air pollution dispersion model and sophisticated spatiotemporal Bayesian data fusion methods. Exposure assessment for traffic-related air pollution is challenging because the pollutants are a complex mixture and vary greatly over space and time. Because extensive direct monitoring is difficult and expensive, a number of modeling approaches have been developed, but each model has its own limitations and errors.

Tracing Sources Of Natural Organic Matter, Trihalomethanes And Metals In Groundwater From A Karst Region, Connie O'Driscoll, Eoin Mcgillicuddy, Peter Croot, Pamela Bartley, John Mcmyler, Jerome Sheahan, Liam Morrison

Articles

Groundwater offers an important source for drinking water around the world; however, groundwater quality is under increasing pressure and is particularly vulnerable in karst areas. Total organic carbon (TOC) is significantly related to groundwater quality and when not removed by water treatment processes can give rise to the formation of disinfection by-products trihalomethanes (THMs) above the level of compliance. This study investigated the source of organic matter giving rise to the THM exceedances in a groundwater supply in a karst area. Results highlighted that source water for this groundwater supply was prone to surface water infiltration linked to rainfall events; …

Contaminants Of Emerging Concern: Reconsidering Our Paradigm Of Water Pollution, Jonathan Gunasti

Pomona Senior Theses

In this senior thesis, I explore contaminants of emerging concern (CECs) and endocrine disrupting compounds (EDCs) and discuss the ways in which these novel contaminants defy traditional notions of pollution. I discuss the history and “emergence” of CECs and EDCs in scientific and public spheres and outline ongoing challenges to recognizing, prioritizing, and understanding the action of these contaminants. I position EDCs within the framework of environmental injustice and health disparities and suggest that these compounds could reinforce multigenerational health inequities. Finally, I perform a pilot analysis of the EDC bisphenol A (BPA) in Mt. Baldy Creek, the Los Angeles …
