Destruction Of Pfoa On Ion-Exchange Resin With Advanced Reduction Processes To Regenerate Resins For Addressing Pfoa Pollution In Drinking Water, Junkui Cui

Theses, Dissertations and Culminating Projects

Per- and polyfluoroalkyl substances (PFAS) have been globally incorporated into various industrial and consumer products since the 1940s. However, concerns about PFAS have gradually grown because of their prevalence, mobility, persistence, bioaccumulation, and adverse impacts on human and environmental health. Unfortunately, traditional water treatment processes inefficiently remove PFAS. Therefore, there is an urgent research need to develop innovative, technically viable, and low cost-treatment processes for the removal of PFAS in water.

Among the established PFAS treatment technologies, ion-exchange (IX) has been extensively applied to drinking water treatment practices due to its adsorption capability and technology maturity. However, IX is highly …

Road Salt-Induced Salinization Of The Upper Paulins Kill River In Newton, New Jersey, Kristine Emily Rogers

Theses, Dissertations and Culminating Projects

Road salt application is a primary factor leading to the salinization of freshwater rivers and streams throughout the Northeastern United States and globally. Rising salinization within fresh water bodies is problematic because it can modify community structure and detritus processing within freshwater ecosystems, induce mortality among macroinvertebrates and other aquatic life, and mobilize metals that can pose harm to human health. Road salts also threaten surface and underground drinking water supplies, kill riparian vegetation, and corrode infrastructure, such as bridges and roads. This research examines 4 1⁄2 years of continuous water quality monitoring data collected from two sensor stations along …

Ancient Bears Provide Insights Into Pleistocene Ice Age Refugia In Southeast Alaska, Flavio Augusto Da Silva Coelho, Stephanie Gill, Crystal M. Tomlin, Marilena Papavassiliou, Sean D. Farley, Joseph A. Cook, Sarah A. Sonsthagen, George K. Sage, Timothy H. Heaton, Sandra L. Talbot, Charlotte Lindqvist

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

During the Late Pleistocene, major parts of North America were periodically covered by ice sheets. However, there are still questions about whether ice-free refugia were present in the Alexander Archipelago along the Southeast (SE) Alaska coast during the last glacial maximum (LGM). Numerous subfossils have been recovered from caves in SE Alaska, including American black (Ursus americanus) and brown (U. arctos) bears, which today are found in the Alexander Archipelago but are genetically distinct from mainland bear populations. Hence, these bear species offer an ideal system to investigate long-term occupation, potential refugial survival and lineage turnover. Here, we present genetic …

Effects Of Lead Exposure On Birds Breeding In The Southeast Missouri Lead Mining District, Rebecka Brasso, Danielle Cleveland, Frank R. Thompson Iii, David E. Mosby, Kathy Hixson, Melissa Roach, Barnett A. Rattner, Natalie K. Karouna-Renier, Julia S. Lankton

United States Geological Survey: Staff Publications

Lead mining in the Southeast Missouri Lead Mining District began in the 1700s and continued for nearly 300 years; the waste piles associated with smelting, mining, and milling of lead ores have released metal residues that have contaminated soil and water in the region. Previous studies in the district have indicated potential harm to wildlife, including birds, because of elevated lead concentrations associated with mining. Exposure to soil-borne lead was correlated with elevated lead concentrations in tissues, inhibition of δ-aminolevulinic acid dehydratase (δALAD), and renal lesions in birds foraging on ground-dwelling invertebrates at contaminated sites (compared to reference sites) in …

Analysis Of Benthic Macroinvertebrate Response To Restoration Flows And Scour In The Trinity River, Northern California, Sarah Gutierrez, Julie Avina

Undergraduate Scholarship

This study investigates the ecological impact of restoration flows and scouring events on benthic macroinvertebrate (BMI) communities within the Trinity River, an ecosystem historically impacted by anthropogenic activities. Central to this study is the examination of how hydrologic alterations, especially the construction of the Lewiston Dam, have influenced these vital ecological indicators. Using data collected earlier in 2023 from a current study by Benjamin King, we analyzed BMI samples from three river sites (Junction City, Pear Tree, and Lorenz Gulch), both prior to and following a major scouring event in January 2023. This paper utilizes statistical analyses, including ANOVA and …

Remote Sensing Of Georgia Tidal Marsh Habitats Using Aerial Photography And Planetscope Satellite Imagery, Harrison M. Currin

College of Graduate Studies: Theses & Dissertations

Globally, tidal marshes cover about 90,800 km. Within the state of Georgia tidal marshes are primarily located behind the barrier islands and total 1,619 km². The combination of high salinity environments and daily inundation, and being dependent on river output, make these dynamic systems. Tidal marshes provide numerous ecosystem services such as carbon and nitrogen sequestration, flood control, coastal protection, and numerous biogeochemical processes. Due to their unique position, tidal marshes are under threat from sea level rise, drought, coastal development, and large-scale disturbance events. Tidal freshwater marshes are especially susceptible to these threats due to their geographic …

The Transition To Low And Near Zero Carbon Emission Ports : Extent And Determinants, Anas Alamoush

World Maritime University Ph.D. Dissertations

Port CO2 emissions are still high due to the dependence of equipment and energy on fossil fuels. This puts the port under pressure stemming from, inter alia, logistics chains, stakeholders and regulations, in addition to not being in line with the Paris Agreement’s goal for industries to decarbonise by mid-century. The research problem suggests that ports need to reduce their high carbon emissions and decarbonise, to contribute to the mitigation of climate change that started hitting hard including worldwide countries ports. However, there are practical and academic gaps that contribute and exacerbate the problem while this phenomenon is not yet …

Climate Insecurity, Shi-Ling Hsu

Scholarly Publications

Global climate change causes climatic events such as hurricanes, droughts, floods, and heat waves to occur more frequently and with greater severity. In addition to inflicting direct harm, climatic events disrupt the flow of commerce and natural resources, creating shortages of goods and services sometimes temporarily, sometimes not. Climate change is getting worse, so climatic events will escalate over time, and as events cumulate, there is the potential for multiple events to heap harm on top of harm, exponentially increasing misery and disruption. What looms is the prospect of shortages of basic life necessities.

A Study On Global Reef Deterioration: Exploring Coral Bleaching, Emily Fernandez

CMC Senior Theses

This thesis is a study on coral bleaching and coral mortality, studying the relationship between variables such as depth, exposure, distance to shore, and temperature for percent bleaching. All of the analyses were made using two different data sets, that contain information about bleaching events in specific regions, and dates, and provide information factors such as depth, temperature, and exposure. Models were created for different relationships of variables for eco-regions, recent data, and countries. I attempted to find relationships between variables such as depth, temperature, exposure, and distance to shore, and how they affect coral bleaching. Unfortunately, I did not …

Pakistan's Contribution To The Global Rise In Conventional Pollution, Emily Warner

CMC Senior Theses

This thesis examines the impact of conventional pollutants on the environment, communities, and individuals in Pakistan. It begins by investigating the causes of conventional pollutants and exploring Pakistan’s agricultural industry, domestic practices, non-renewable energy sources, and industrial practices (the brick industry, leather tanning industry, and textile industry). It then analyzes factors that continue to contribute to conventional pollution in Pakistan such as economic incentives, politics, and traditional practices within industries. Exploring the measures that have been taken by Pakistan and other organizations to decrease conventional pollutants, it then suggests potential opportunities for improvement.

Evolutionary History And Adaptation To Salinity In American Alligators, John Konvalina

Electronic Theses and Dissertations, 2020-2023

Stressful environments can commonly be found at the edge of a species range and may be a driver for adaption in suboptimal environments. Furthermore, the edge of a species' range can expand and contract over time, resulting in multiple independent invasions of the same stressful habitat. Elucidating population genetic structure and demographic history can aid in determining the which geologic factors impact range distributions and when climatic changes occurred driving genetic patterns observed in contemporary populations. Moreover, populations at the edge of the species range may adapt to the stressful environments that occur at the range edge and exhibit genetic …

Plastic Storage In River Sediments Across An Urbanization Gradient In The Ipswich Watershed In Massachusetts, Jackie L. Harris

Honors Theses and Capstones

The importance of plastic pollution research has become apparent as plastic pollution has increased exponentially since its introduction in the 1950s. Plastics mechanically break down into minuscule particles called microplastics, which are plastic particles with a size range of 0.1 micrometers (μm) to 5 millimeters (mm). Most of the research on microplastic pollution has centered around marine ecosystems rather than freshwater ecosystems. More freshwater microplastic research to date is emerging but is still nascent and sparse. Furthermore, the idea that rivers are merely conduits of microplastics to the ocean is even more limited and ignores microplastic loading and retention in …

Climate Change And The Law Of National Security Adaptation, Mark P. Nevitt

Faculty Articles

The Department of Defense (DoD) is the largest employer in the world, owns and operates an enormous global real estate portfolio, and emits more Greenhouse Gases (GHGs) than many nations. Entrusted with the national security, the DoD is now threatened by a new enemy—climate change. Climate change imperils national security infrastructure while undermining the military’s capacity to respond to climate-driven disasters at home and abroad. However, legal scholarship has yet to address what I call “the law of national security adaptation” and related questions. For example, how do environmental and climate change laws apply to the U.S. military? What laws …

Climate Change And The Specter Of Statelessness, Mark P. Nevitt

Faculty Articles

What happens when climate change extinguishes entire nations? Neither international nor environmental law has provided a satisfactory answer to this weighty question. Climate change-induced flooding, storm surge, and sea level rise threaten the territorial integrity and habitability of several small island developing states, raising the specter of statelessness. We know that climate catastrophe is coming, but we have failed to take the necessary steps to safeguard several developing nations. This Article argues that innovative legal and policy solutions are needed today to prevent nation extinction tomorrow. I focus on two potential international governance solutions: the U.N. Framework Convention on Climate …
