Calculating And Comparing Bioaccessible Lead Concentrations In Soils From The Garfield Ridge, West Elsdon, And Lakeview Community Areas Using A Pbet And A Mehlich-3 Digestion Method, Emma Sznewajs
DePaul Discoveries
Lead exposure through soil poses potential health risks to those in areas with higher soil-Pb levels, specifically urban areas. The soil-lead concentrations recommended by the EPA are based on measurement of total lead concentration, yet only a percentage of the total lead can actually be absorbed into the body. The percentage of lead in soil that can be absorbed into the blood through ingestion is reffered to as bioaccessible lead and can be a more accurate way of measuring potential dangers of lead in soils. This study measured the amount of bioaccessible lead in the community areas of West Elsdon, …

Equilibrium And Kinetic Studies Of Crude Oil Sorption On Unmodified And Modified Napier Grass, Amalachukwu Ifeyinwa Obi, Vincent Ishmael Ajiwe, Chinwe Priscilla Okonkwo
Makara Journal of Science
Nowadays, natural organic adsorbents are widely used to clean up oil from spills owing to their effectiveness, affordability, and biodegradability. In this study, Napier grass, a widely available agricultural material, was used to remove crude oil from aqueous media. The Napier grass was modified via a mild acetylation process to improve its hydrophobicity. The modification increased the Brunauer–Emmett–Teller surface area of the grass from 180.07 to 271.13 m2/g. Fourier-transform infrared analysis revealed that the modification endowed the originally hydrophilic Napier grass with hydrophobicity. The oil sorption processes were based on monolayer physisorption and controlled by film diffusion. The …

Preliminary Data Of Potentially Hazardous Radon Concentrations In Modrič Cave (Croatia), Robert Lončarić, Vanja Radolić, Maša Surić, Igor Miklavčić, Matea Šatalić, Dalibor Paar, Lukrecija Obšivač
International Journal of Speleology
Instigated by relatively high cave-air CO2 concentrations in Modrič Cave (Croatia) recorded for the purpose of speleothem-based paleoclimate research, we established preliminary monitoring of radon (222Rn) concentrations within the cave for a 4.5-year period (2018–2022). As radioactive geogenic gas, radon, which often correlates with cave-air CO2 concentrations, presents a potential health hazard in cases of longer exposure time in high concentration conditions. Since the Modrič Cave is open to tourists and long-term scientific research has been performed within, a safety assessment for radon concentrations was essential. The integrated measurements of radon concentrations were performed by passive …

Western Kentucky University Stormwater Utility Survey 2023, Warren Campbell, Emily G. Davis
SEAS Faculty Publications
The main goal of this survey is to identify as many U.S. Stormwater Utilities (SWUs) as possible. Because many stormwater professionals do not have the time to respond to questionnaires, our primary method of identification was Internet searches. We searched key terms such as “stormwater utility”, “stormwater fee”, and “drainage fee”. We scoured online municipal codes such as Municode, AmLegal, Sterling, LexisNexis, General Code, and others. We searched through many city web websitesing to find utilities. We have also had many people contact me to update fees and identify new utilities. However, the data primarily comes from Internet sources and …

Assessing Boil Water Notices As Health-Risk Communication: Risk Perceptions, Efficacy, And Compliance During Winter Storm Uri, Ashleigh M. Day, Sydney O'Shay, Khairul Islam, Matthew W. Seeger, Shawn P. Mcelmurry
Open Data at Wayne State
Winter Storm Uri was an extreme disaster that impacted much of the United States during February of 2021. Texas and Oklahoma were generally not prepared for such an event and experienced massive power grid failures. This led to cascading risks including water system disruptions and many boil water notices (BWNs). The breakdown of some communication channels and the inability to enact protective actions due to power outages, as well as travel limitations on public roads, complicated both dissemination and implementation. Under these conditions, a non-representative, cross-sectional, survey was collected to assess individuals experience BWNs and how perceived efficacy impacts compliance. …

Possible Impact Of Additives In Artificial Turf On Aquatic Life In The San Francisco Estuary, Elena Galkina
Master's Projects and Capstones
The use of artificial turf fields as a replacement for natural turf has been increasingly promoted as a green solution to reduce water usage, maintenance costs, and the need for pesticides. However, the potential environmental impacts of artificial turf fields are poorly understood, particularly in the context of the San Francisco Estuary, which is one of the largest and most polluted estuaries in the United States. This paper investigates the potential contribution of artificial turf from sports fields to the microplastic and chemical pollution of the San Francisco Estuary during artificial turf’s use and maintenance life stage. The study synthesizes …

Feasibility Analysis Of Aeronet Lunar Aod For Nighttime Particulate Matter Estimation, Kwang Nyun Kim, Seung Hee Kim, Sang Seo Park, Yun Gon Lee
Institute for ECHO Articles and Research
Several studies have attempted to estimate particulate matter (PM) concentrations using aerosol optical depth (AOD), based on AOD and PM relationships. Owing to the limited availability of nighttime AOD data, PM estimation studies using AOD have focused on daytime. Recently, the Aerosol Robotic Network (AERONET) produced nighttime AOD, called lunar AOD, providing an opportunity to estimate nighttime PM. Nighttime AOD measurements are particularly important as they help fill gaps in our understanding of aerosol variability and its impact on the atmosphere, as there are significant variations in AOD between day and night. In this study, the relationship between lunar AOD …

Partitioning And Microdosimetry Of Plutonium-239 And 55-Iron In Environmental Bacteria Grown In Liquid Cultures, Lisa Manglass
All Dissertations
The work presented herein provides quantitative data related to bacteria exposed in situ to two radionuclides relevant to nuclear sensing: plutonium-239 (239Pu) and iron-55 (55Fe). Originally motivated by the fundamental science underlying biosensing, liquid cultures of Pseudomonas putida and Escherichia coli were exposed to radionuclides over the course of 15-day experimental periods with the intent of gaining insight into the response of these bacteria. An essential component of characterizing or utilizing this response in a meaningful way is an understanding of the dose leading to that response. This dissertation narrows the knowledge gap associated with dose-response …

Impacts Of Preferential Flow On Tc-99and Np-237 Vadose Transport In Soils At The Savannah River Site, Josh Parris
All Theses
Since the 1950s, the United States has produced approximately 90,000 metric tons of spent nuclear fuel (SNF) (Office of Nuclear Energy, 2022); however, no long-term storage solutions are available. Technecium-99 and neptunium-237, two fission products found in SNF, readily form highly mobile species in oxidizing conditions (Hu, 2008; Bondietti, 1979) and have respective half-lives of 2.13 x 105 and 2.14 x106 years (Hu, 2010). Considering these characteristics, 99Tc and 237Np are two risk-driving isotopes found in SNF storage. The process of macropore-facilitated preferential flow, transport through cracks within a soil matrix, has been recognized to increase …

Soil Health And Remediation For Urban Gardens In Utah, Melissa Chilinski
All Graduate Plan B and other Reports
Urban environments are at an increased risk of soil contamination and poor soil health due to anthropogenic causes. As healthy farmland is developed, new urban farmers and gardeners are often left growing food on unwanted land with unknown histories of previous use. Varied research and methods for obtaining healthy soils can cause new growers to make decisions that negatively impact soil health and fertility, or on the other hand, conflicting information can cause individuals to become unnecessarily fearful of common soil contaminants and their effect on human health. Common soil contaminants, like trace metals (often referred to as heavy metals) …
