An Assessment Of Data Related To Inspections Of Risk Factors For Public Swimming Pools, Shanita Shack, Maurice Redmond, R. Christopher Rustin
Environmental Health Sciences Faculty Publications
Background: The Georgia Department of Public Health (DPH) is mandated to ensure that public swimming pools are safe for those who use them. This mandate is carried out by the DPH and local environmental health professionals through regulations and inspections. In 2015, legislation was introduced proposing to reduce the authority of the DPH to inspect certain pool types (apartments, subdivision, condominiums) and thus reduce regulatory protections in place for swimmers. To ensure that the DPH had current information on the risks associated with pools, the EH team, with assistance from a graduate student, analyzed inspection data to evaluate risk factors …

Determining The Effects Of The Think Risk Initiative As Implemented By The Southern Nevada Health District, Karalin Nichole Cronkhite
UNLV Theses, Dissertations, Professional Papers, and Capstones
In the United States, someone becomes infected with a foodborne illness every 2 seconds, is hospitalized by a foodborne illness every 4 minutes and dies due to a foodborne illness every 3 hours. Foodborne illness is preventable, yet each year, 1 in 6 Americans is affected by it from contaminated foods or beverages. There are over 250 different foodborne diseases, and in 2015, there were 73 confirmed cases of Salmonella infection in Southern Nevada alone. Since the emergence of public health, food establishment inspections have been an important part of the regulation of food safety. Risk-based inspections were developed by …
Effects Of Antibiotic Mixtures Across Marine Intertidal Trophic Levels: Examining Environmentally-Relevant Contaminant Concentrations, Jaclyn Rebecca Teixeira
Effects Of Antibiotic Mixtures Across Marine Intertidal Trophic Levels: Examining Environmentally-Relevant Contaminant Concentrations, Jaclyn Rebecca Teixeira
Dissertations and Theses
Approximately 48% of Americans use prescription drugs within each 30-day period, and there are signs this trend is increasing. Although many studies track pharmaceuticals’ fates in contaminating waterways, only fairly recent efforts have examined the potential impacts of these drugs on non-target organisms. The antibiotics sulfamethoxazole and trimethoprim, often prescribed together to treat bacterial infections, have been detected worldwide in marine and estuarine environments at concentrations up to 700-800 ng/L each. Toxic effects of these drugs have been identified in freshwater organisms, with synergistic effects observed in short-term studies of mixtures of the two; however, little research has examined possible …

Rickettsia philipii (type strain “Rickettsia 364D”), the etiologic agent of Pacific Coast tick fever (PCTF), is transmitted to people by the Pacific Coast tick, Dermacentor occidentalis. Following the first confirmed human case of PCTF in 2008, 13 additional human cases have been reported in California, more than half of which were pediatric cases. The most common features of PCTF are the presence of at least one necrotic lesion known as an eschar (100%), fever (85%), and headache (79%); four case-patients required hospitalization and four had multiple eschars. Findings presented here implicate the nymphal or larval stages of D …

Manufacturer Perspectives On Content Transparency And Material Health In The Us Building Products Industry, Alexandra A. Muller
Manufacturer Perspectives On Content Transparency And Material Health In The Us Building Products Industry, Alexandra A. Muller
Open Access Theses
Flawed U.S. federal regulation of chemicals has resulted in a materials market that undervalues human and environmental health in favor of the more traditional attributes of price, performance and aesthetics. In the building products industry, global, dynamic supply chains and proprietary information concerns further complicate the task of assessing the material health of products.
Voluntary material health programs in the green building industry are intended to incentivize the manufacture and selection of safer products by getting companies to gather and assess ingredient, hazard and risk information from their supply chain. Building product manufacturers considered early adopters of the main material …
Improving The Roadside Environment Through Integrating Air Quality And Traffic-Related Data, Christine M. Kendrick
Improving The Roadside Environment Through Integrating Air Quality And Traffic-Related Data, Christine M. Kendrick
Dissertations and Theses
Urban arterial corridors are landscapes that give rise to short and long-term exposures to transportation-related pollution. With high traffic volumes, congestion, and a wide mix of road users and land uses at the road edge, urban arterial environments are important targets for improved exposure assessment to traffic-related pollution. Applying transportation management strategies to reduce emissions along arterial corridors could be enhanced if the ability to quantify and evaluate such actions was improved. However, arterial roadsides are under-sampled in terms of air pollution measurements in the United States and using observational data to assess such effects has many challenges such as …

High consumption lifestyles led to a rapid decline in natural resources. The daily gestures of the people of the world use a quantity massive resource and energy that cannot be replaced. Decision makers of the world are invited to consider what changes will be needed to focus about sustainable and sustainable practices if we want to continue living in the way which we have become accustomed to. The development of renewable energies was a first step towards total sustainable development. Recently, however, we have seen a new way to reduce negative impacts on the rights of the Earth: changes in …
The United States, China, And Climate Change: An Analysis Of The Us-China Climate Pact And Its Implications For International Climate Negotiations, Joesph Fiorile
Honors Theses
Climate change increasingly is becoming a major issue for the international community. It is contributing to rising global temperatures, rising sea levels, drought, natural disaster intensification, and ecological damage, amongst other things. A scientific consensus has emerged over recent years that implicates greenhouse gases, chief amongst them carbon dioxide, for causing global warming. Climate scientists overwhelmingly agree that the greenhouse gas effect has been caused in large part by the spike of human emissions since the dawn of the Industrial Revolution. To reverse the problem, the density of greenhouse gases in Earth’s atmosphere, especially carbon dioxide, has to be reduced. …

Polychlorinated Biphenyl (Pcb) Pollution Of The Hudson River: Social Policy And Health Considerations, Laura Schad
Honors Theses
The purpose of this paper is to examine pollution in the Hudson River and the role General Electric has had in creating this problem. The focus will be on social issues and problems that have emerged as a result of the environmental damage from pollution. Until recently, there was little research done on the health and environmental justice issues that impact the New York communities where GE’s factories were located. This paper examines the material collected and studies that were done which document Hudson River pollution and the contributions as well as cleanup efforts of General Electric. The overall problems …
Evaluating Infection Prevention Strategies In Out-Patient Dialysis Units Using Agent-Based Modeling, Joanna R. Wares, Barry Lawson, Douglas Shemin, Erika D'Agata
Evaluating Infection Prevention Strategies In Out-Patient Dialysis Units Using Agent-Based Modeling, Joanna R. Wares, Barry Lawson, Douglas Shemin, Erika D'Agata
Department of Math & Statistics Faculty Publications
Patients receiving chronic hemodialysis (CHD) are among the most vulnerable to infections caused by multidrug-resistant organisms (MDRO), which are associated with high rates of morbidity and mortality. Current guidelines to reduce transmission of MDRO in the out-patient dialysis unit are targeted at patients considered to be high-risk for transmitting these organisms: those with infected skin wounds not contained by a dressing, or those with fecal incontinence or uncontrolled diarrhea. Here, we hypothesize that targeting patients receiving antimicrobial treatment would more effectively reduce transmission and acquisition of MDRO. We also hypothesize that environmental contamination plays a role in the dissemination of …
Evaluation Of Pulmonary Function Among Workers Engaged In The Manufacture Of Hydraulic Fracking Ceramic Proppant, Humairat H. Rahman
Evaluation Of Pulmonary Function Among Workers Engaged In The Manufacture Of Hydraulic Fracking Ceramic Proppant, Humairat H. Rahman
USF Tampa Graduate Theses and Dissertations
Workers involved in hydraulic fracking processes are exposed to various types of chemicals and dusts in their workplaces, such as proppants, which hold open the fissures created in the fracking process. Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to assess the potential inhalation hazards of ceramic proppant. Male workers (n = 100) from a producer of ceramic proppant were evaluated with pulmonary function test data collected and evaluated using The American Thoracic Society (ATS) acceptability criteria. A comparison group was selected …
Human Health Risk Characterization Of Petroleum Coke Calcining Facility Emissions, Davinderjit Singh
Human Health Risk Characterization Of Petroleum Coke Calcining Facility Emissions, Davinderjit Singh
USF Tampa Graduate Theses and Dissertations
Calcined coke is a high quality carbon material produced by calcining green petroleum coke. Calcining is the process of heating green petroleum coke in a kiln to remove excess moisture, extract all remaining hydrocarbons, and modify the crystalline structure of the coke into a denser, electrically conductive product. The final product, calcined coke, is primarily used to make carbon anodes for the aluminum industry and recarburizing agent for industries such as the steel industry. If not appropriately controlled, the calcining process could lead to excess production of particulate emissions from either handling or storing of raw coke, or from the …

Microcystins are acute hepatotoxins of increasing global concern in drinking and recreational waters and are a major health risk to humans and animals. Produced by cyanobacteria, microcystins inhibit serine/threonine protein phosphatase 1 (PP1). A cost-effective PP1 assay using p-nitrophenyl phosphate was developed to quickly assess water and rumen content samples. Significant inhibition was determined via a linear model, which compared increasing volumes of sample to the log-transformed ratio of the exposed rate over the control rate of PP1 activity. To test the usefulness of this model in diagnostic case investigations, samples from two veterinary cases were tested. In August …
The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown
The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown
Journal of Environmental and Resource Economics at Colby
This paper looks at the impact of electric vehicles on CO2 emissions specifically based on the type of electricity used in each New England state analyzed. The research looks at the question of whether or not emissions will in fact be lowered as electric cars start to take the majority of vehicles used instead of the conventional cars that take up a much larger percent of the motor vehicles used today. Taking into account the use of electricity and how many sources of electricity also release a substantial amount of emissions, we see how valid the public opinion of electric …

The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler
Journal of Environmental and Resource Economics at Colby
This paper seeks to address the effect of “Spare the Air” pollution control alerts in the San Francisco Bay Area in California on the use of Bay Area BikeShare as a form of transportation. By observing the daily alerts on the duration of rides using BikeShare, this paper observes if STA ozone alerts are effective in changing human behavior. The results show that only as a subscriber to the BikeShare program and on an alert day does duration decrease whereas customers regardless of if it is an alert day will ride more often and at longer distances. The results contradict …
Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou
Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou
Journal of Environmental and Resource Economics at Colby
This paper examines the relationship between the socioeconomic attributes of a state and its green commercial office space adaptation. I hypothesize that a state with high socioeconomic status will have a high green building adoption. Additionally, the high socioeconomic status states may be more likely to invest in green commercial buildings with higher LEED certification levels, and various types of LEED commericial office projects are affected by the socoeconomic attributes differently.
Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda
Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda
Journal of Environmental and Resource Economics at Colby
This paper examines the stock market reaction to the British Petroleum oil spill on April 20, 2010. This event study looks at different sectors that may be affected by the oil spill. It finds that different industries do not have significant abnormal returns, with two exceptions. First, utilities companies have a very small positive abnormal return for a short period of time after the incident. Second, when only looking at BP's direct competitors, there is a statistically significant negative abnormal return, implying that BP's competitors are punished for BP's mishap.
Media Effects On Solar Panel Installations Across 20 States, Casey Romeo
Media Effects On Solar Panel Installations Across 20 States, Casey Romeo
Journal of Environmental and Resource Economics at Colby
This paper looks at the relationship between media coverage of solar power and the solar panel installation at a state level. Specifically, it aims to find if more newspaper articles cause more households to adopt solar energy. Use data from 20 states from 2009 to 2014. I find that there is a modest, yet positive and statistically significant relationship between newspaper articles and installations, which suggests that the media does influence the decision to install solar panels. There is possible endogeneity between these two variables. Disentangling this endogeneity is beyond the scope of this research and would be a topic …
Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff
Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff
Journal of Environmental and Resource Economics at Colby
This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, respectively. Although the results are not entirely statistically significant, I find that the initiatives lead to increases in total renewable energy consumption and decreases in total energy use.

Journal of Environmental and Resource Economics at Colby
This study investigates how food companies were affected by the International Agency for Research on Cancer’s report that linked processed meat and red meat consumption to increased risk of cancer. The results indicate that neither fast food companies nor meat producers were greatly affected by the announcement in the days immediately following the release.
Property Value Changes From Public Transportation: How The Greenbush Commuter Line Affected Property Values, Sarah C. Evans
Property Value Changes From Public Transportation: How The Greenbush Commuter Line Affected Property Values, Sarah C. Evans
Journal of Environmental and Resource Economics at Colby
Prior studies have investigated the impact on property values to the proximity of established public transportation stations. Public transportation is thought to increase value of towns and properties, giving residents more options for transportation to and around the city. Both benefits and consequences of public transportation exist, allowing for either a raise or lower of property values in towns with stops. This paper analyzes the Greenbush Commuter line in Massachusetts, seeing if the proximity to the stops has an affect on the property of values in the towns. A difference – in – difference model is used to investigate a …
The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz
Journal of Environmental and Resource Economics at Colby
This paper examines the effectiveness of the Colby College electricity reduction competition in altering students’ behavior to conserve electricity. The Colby College electricity reduction competition is an information-based policy that Colby implemented to promote the conservation of electricity, which are a major contributor to greenhouse gas (GHG) emissions in the United States. The study analyzes if different residence halls reduce electricity consumption by different amounts during the competition period. Results indicate that only 4 of 22 residence halls reduced electricity usage during competition periods in a statistically significant manner. The study concludes that the electricity competition at Colby College is …

Of Life And Limb: The Failure Of Florida's Water Quality Criteria To Test For Vibrio Vulnificus In Coastal Waters And The Need For Enhanced Criteria, Regulation, And Notification To Protect Public Health, Felicia Thomas
Student Works
The nefarious duo of warming oceans and rising sea levels has created a menacing yet lesser-known climate change-induced problem: an increase in sea-borne diseases. For most, the biggest concern when diving into the ocean is a possible, though exceedingly rare, shark encounter; however, it is the unexpected, unseen risk of Vibrio vulnificus that poses the greater danger. Part I of this paper discusses Vibrio vulnificus cases along the coasts of Florida, examining both the illnesses that were contracted through exposure of open wounds to seawater and those contracted through the consumption of raw oysters from the Gulf Coast. Part II …
