Development of an Analytical Method for Quantification of Endocrine-Disrupting Phytoestrogenic Compounds in Estuarine Environment Using UHPLC-MS/MS

Qi, Jingyi (2018-04-27)

Endocrine disrupting compounds (EDCs) are nearly ubiquitous in the daily lives of individuals around the globe. Phytoestrogenic polyphenols (PEPPs, also known as phytoestrogens) represent a subgroup of EDCs. They are ...

Enhancing understanding of mineral accessible surface area to improve simulation of mineral reaction rates in porous media

QIN, Fanqi (2021-07-19)

Geological formations have great potential for large scale carbon sequestration, where the CO2 is mineralized through geochemical reactions. These reactions are rather complex and can potentially alter the formation ...

Evaluation of an Algal Turf Scrubber™ (ATS) Approach for the Remediation of Perfluoroalkyl Substances (PFAS)

Lopes Viticoski, Roger (2019-04-17)

Per- and polyfluoroalkyl substances are a large group of synthetic organic chemicals ubiquitous and persistent in the environment due to their fluorinated alkyl chains. Existing methods for remediation of mixtures of PFAS ...

Evaluation of Subsurface Gypsum-rich Rock in the Context of Geologic Carbon Sequestration

Newsome, Jamie (2023-11-29)

Geological carbon sequestration is a promising means of reducing atmospheric carbon dioxide emissions by capturing CO2 gas and storing it long term in subsurface porous rock. The goal of geologic carbon sequestration is ...

Hydrodynamic and Water Quality Modeling of Lake and Estuary Systems Considering Inflow and Outflow Effects

Tasnim, Bushra (2023-12-06)

Algal bloom, fish kill, hypoxia, and toxicity are some of the water quality issues faced by many waterbodies, from lakes to estuaries. Internal or external nutrients cause excess growth of algae and then lead to low or no ...

Identification of Selenium Reducing Species Within and Suggested Optimization of a Passive Biological Reactor

Grantham, Patrick (2016-12-09)

As concern for the environment moves to the forefront of the issues considered most pressing by society, mankind is becoming increasingly aware of the harmful things it discharges into the ecosystem in the name of industry ...

Incorporating Consideration for Poor Households into U.S. Environmental Protection Agency Affordability Methodologies for Drinking Water Treatment

Gingerich, Daniel (2013-07-10)

In the 1996 Amendments to the Safe Drinking Water Act, Congress charged the U.S. Environmental Protection Agency (EPA) with developing affordability methodologies to determine if new drinking water treatment regulations ...

Land Application of Treated Wastewater within the Black Belt of Alabama

Clark, Carey (2023-08-09)

The Black Belt of Alabama is a region of the United States that has seen its population decrease and poverty rise over the last century. The Black Belt was a thriving part of Alabama due to the rich, fertile soil. The dark ...
