Investigating The Mechanisms Driving Mercury Reduction And Emissions In Soil, Hamil Patel

Student Theses

The water-induced emission of mercury from soil has been studied, but a complete understanding of the mechanisms driving mercury reduction and emission in soil has not been reached. The current understanding is an immediate expulsion of soil gaseous mercury upon water treatment and an upward transport of dissolved soil ionic mercury as the water evaporates. We analyzed emissions from several types of samples using various methods to further our understanding on the mechanisms involved. Light-induced emissions from aqueous samples of humic acid (HA) spiked with mercury (II) chloride (HgCl₂) showed that at higher concentrations of HA, less mercury …

Effects Of Experimental Scale On The Adsorption Of Two Pharmaceutical Drugs Detected In Municipal Wastewater Effluent, Michael Moore

Master's Theses

Pharmaceutical drugs are being produced and consumed in increasing quantities every year and are poorly treated by conventional wastewater treatment processes, leading to increasing detection of such compounds in surface water, groundwater, and municipal drinking water. Soil aquifer treatment (SAT) is a promising method for treating these emerging compounds through combined adsorption and degradation of target compounds in soil. This thesis examines the consistency of results from typical studies like adsorption isotherms and soil columns utilized in analysis of SAT performance, across varying experimental scales. The adsorption behavior of two pharmaceuticals was investigated as a function of experimental scale and …

Speciation With Gene Flow In A Narrow Endemic West Virginia Cave Salamander (Gyrinophilus Subterraneus), Evan H. Campbell Grant, Kevin P. Mulder, Adrianne B. Brand, Douglas B. Chambers, Addison H. Wynn, Grace Capshaw, Matthew L. Niemiller, John G. Phillips, Jeremy F. Jacobs, Shawn R. Kuchta, Rayna C. Bell

United States Geological Survey: Staff Publications

Due to their limited geographic distributions and specialized ecologies, cave species are often highly endemic and can be especially vulnerable to habitat degradation within and surrounding the cave systems they inhabit. We investigated the evolutionary history of the West Virginia Spring Salamander (Gyrinophilus subterraneus), estimated the population trend from historic and current survey data, and assessed the current potential for water quality threats to the cave habitat. Our genomic data (mtDNA sequence and ddRADseq-derived SNPs) reveal two, distinct evolutionary lineages within General Davis Cave corresponding to G. subterraneus and its widely distributed sister species, Gyrinophilus porphyriticus, that …

Information Sources, Perceived Personal Experience, And Climate Change Beliefs, Sonny Rosenthal

Research Collection College of Integrative Studies

This study proposes and tests a model of serial mediation based on the norm activation model and value-belief-norm theory. It argues that beliefs about climate change are related to perceived personal experience, which is related to the use of different information sources. Structural equation modeling of survey data from 1084 adult residents of Singapore found mixed support for three hypotheses. Results showed that perceived personal experience of climate change was related to the use of traditional media (β = 0.20), social media (β = 0.16), and interpersonal sources (β = 0.13), but not institutional sources. Perceived personal experience of climate …

Damming Sustainability: How Social And Environmental Networks Influence The Construction And Management Of Large Dams In The Amazon Basin, V. Miranda Chase

Graduate Doctoral Dissertations

,p>Dams are powerful structures that engender a flood of controversies. These projects face great criticism from numerous groups, many of whom succeed in influencing such enterprises. This research is an in-depth study on dam-related social and environmental movements in the Amazon: how they are created and internally organized; how members share information and resources, how they identify alternatives; and how they design strategies and implement agendas. Social movements include, but are not limited to, domestic and international nongovernmental organizations (NGOs), academic researchers, journalists, religious organizations, grassroots associations, and large private foundations. They create formal or informal coalitions and design …

Climate Change Impacts And Projections For The Greater Boston Area: Findings Of The Greater Boston Research Advisory Group Report, Ellen Douglas, Paul Kirshen

School for the Environment General Publications

During the writing of the inaugural Boston Research Advisory Group (BRAG) report both NASA and NOAA announced that 2015 was the warmest year on record, beating the previous record set in 2014, by 0.29 °F. Just five years later (during the writing of this report), NASA announced that 2020 had tied 2016 for the warmest year, breaking the previous record by a stunning 1.84 °F, and that the last seven years have been the warmest seven-year period on record.

These observations support the assertion made in the sixth and most recent assessment by the Intergovernmental Panel on Climate Change , …

Within‑Marsh And Landscape Features Structure Ribbed Mussel Distribution In Georgia, Usa, Marshes, William K. Annis, Elizabeth A. Hunter, John M. Carroll

United States Geological Survey: Staff Publications

Ribbed mussels, Geukensia demissa, are marsh fauna that are used in coastal management and restoration due to the ecosystem services they provide. Ribbed mussel restoration efforts may be improved with a greater understanding of the environmental drivers of ribbed mussel distribution at multiple spatial scales to predict areas where restoration could be successful. This study sought to estimate the effects of within-marsh (4 m) and landscape (500 m) factors on ribbed mussel distribution. Ribbed mussel densities were surveyed at 11 sites along the coast of Georgia, USA, and overlaid with spatial data for within-marsh factors (elevation, distance to marsh …

Transformative Ecoliteracy Development In Postsecondary Education: Cultivating Intentional Relationships Through Garden-Based Learning, Shevawn Armstrong

Dissertations and Theses

Education can play a critical role in empowering learners to address the global, complex, and interconnected sustainability problems humanity currently faces. Ecoliteracy, as an educational aim, may support the cultivation of values, attitudes, and skills required for the development of sustainability solutions and our collective ability to design regenerative ways of living. However, empirical research that explores and supports the development of ecoliteracy in adults is limited. This grounded theory action research study aimed to contribute to this body of knowledge. This study explored how adult ecoliteracy and practical gardening skills may be cultivated through an intentionally designed, holistic, garden-based …

Utilizing Novel Field And Data Exploration Methods To Explore Hot Moments In High-Frequency Soil Nitrous Oxide Emissions Data: Opportunities And Challenges, Christine S. O'Connell, Tyler L. Anthony, Melanie A. Mayes, Tibisay Pérez, Debjani Sihi, Whendee L. Silver

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Soil nitrous oxide (N₂O) emissions are an important driver of climate change and are a major mechanism of labile nitrogen (N) loss from terrestrial ecosystems. Evidence increasingly suggests that locations on the landscape that experience biogeochemical fluxes disproportionate to the surrounding matrix (hot spots) and time periods that show disproportionately high fluxes relative to the background (hot moments) strongly influence landscape-scale soil N₂O emissions. However, substantial uncertainties remain regarding how to measure and model where and when these extreme soil N₂O fluxes occur. High-frequency datasets of soil N₂O fluxes are newly possible …

Improved Methodology For Monitoring The Impact Of Mining Activities On Socio-Economic Conditions Of Local Communities, Binay Prakash Pandey, Devi Prasad Mishra

Journal of Sustainable Mining

Mining activities can cause tangible socio-economic improvements in the surrounding regions. Such potential has not been fully realized, owing to the fact that the socio-economic impact assessment processes exercised in India merely predict the footprint of industrial activity on the surrounding population. Consequently, project proponents are mandated to implement a management plan in cases of foreseeable negative consequences. However, both, the assessment study, as well as the process of implementation of a management plan, are riddled with significant gaps and limitations. Primary data collected for this research makes it apparent that, in comparison to the revenue generated from the mining …

A Critical Review Of Bioaccumulation And Biotransformation Of Organic Chemicals In Birds, Dave T. F. Kuo, Barnett A. Rattner, Sarah C. Marteinson, Robert Letcher, Kim J. Fernie, Gabriele Treu, Markus Deutsch, Mark S. Johnson, Sandrine Deglin, Michelle Embry

United States Geological Survey: Staff Publications

A literature review of bioaccumulation and biotransformation of organic chemicals in birds was undertaken, aiming to support scoping and prioritization of future research. The objectives were to characterize available bioaccumulation/ biotransformation data, identify knowledge gaps, determine how extant data can be used, and explore the strategy and steps forward. An intermediate approach balanced between expediency and rigor was taken given the vastness of the literature. Following a critical review of >500 peer-reviewed studies, >25,000 data entries and 2 million information bytes were compiled on >700 organic compounds for ~ 320 wild species and 60 domestic breeds of birds. These data …
