An Analysis Of Pollution In Liverpool, Uk, Luke W. Lawson
An Analysis Of Pollution In Liverpool, Uk, Luke W. Lawson
Honors Theses
Within this experiment the different levels of pollution in areas around Liverpool were tested. These areas were Stanley Park, Lunt Meadows, and Woolton Road. At Stanley Park one of two transects had a geochemical analysis as well as magnetic measurements run to investigate source attribution within the urban environment resulting in data showing high variability in soil properties among the transect. With data supporting evidence of diamagnetic, paramagnetic, and ferromagnetic properties in soil along the same transect. At Lunt Meadows, through the use of XRF for soil samples and nitrate and phosphate testing for water samples, it was found that …
Trends In Cyanotoxin Production Potential In China Lake: An Edna Analysis Of Microcystis And Dolichospermum And The Environmental Drivers Of Cyanotoxin Production, Gennifer M. Rubin
Trends In Cyanotoxin Production Potential In China Lake: An Edna Analysis Of Microcystis And Dolichospermum And The Environmental Drivers Of Cyanotoxin Production, Gennifer M. Rubin
Honors Theses
Episodes of cyano-harmful algal blooms (cyano-HABs) are hypothesized to be exacerbated by the effects of climate change. However, the dynamics of the interactions between elements of climate change and toxigenic cyanobacteria proliferation are not well defined. China Lake is the drinking water source for 7 municipalities in the Kennebec County and is one of many lakes in central Maine that has been subjected to high levels of cyano-HABs and microcystin toxin contamination in recent years. Monitoring the toxicity of these blooms in relation to various aspects of climate change may lead to identification of the major drivers of microcystin production …
Sustainable Agriculture: How France Promotes Sustainability, Jordan Pulling
Sustainable Agriculture: How France Promotes Sustainability, Jordan Pulling
Honors Theses
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
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 …
Kinetic Modeling Of Catalytic Aerogels, Yi Cao
Kinetic Modeling Of Catalytic Aerogels, Yi Cao
Honors Theses
As pollution becomes an increasing concern globally, strict regulations have been set on vehicle pollutant emissions. The three-way catalytic converter is capable of converting toxic emissions such as carbon monoxide, unburned hydrocarbons and nitrogen oxides to less hazardous waste such as carbon dioxide, water, and nitrogen. Current catalysts employ platinum group metals, which are expensive and environmentally damaging to mine. Catalytically-active aerogels such as Co-Al, Cu-Al and V-Al aerogels have shown promise as alternatives to these metals. The work presented here adapts and extends a global kinetic model which predicts the conversion of hydrocarbons and carbon monoxide on platinum catalyst …
Proton Induced X-Ray Emission Spectrometry Of Atmospheric Aerosols At Piseco Lake, Adam Margulies
Proton Induced X-Ray Emission Spectrometry Of Atmospheric Aerosols At Piseco Lake, Adam Margulies
Honors Theses
Chemical studies of lakes and aerosols in the Adirondack region of New York State have found evidence of environmental pollution resulting in acid rain. We obtained air samples for July and September 2012 from Piseco Lake and analyzed particulate depositions with Proton Induced X-ray Emission (PIXE) spectrometry. We detected an array of light elements, including sulfur particulates in the 0.25 - 8 μm range, possibly stemming from coal combustion in the Appalachians and Mid-West of the United States. We also found systematic errors with the accelerator charge integration system due to beam spreading after the beam passes through the target. …
Documenting The Anthropogenic Impact On Ballston Lake New York From A Short Core Using Stable Isotopes Of Carbon And Nitrogen And Trace Metals, Taylor S. Labrecque
Documenting The Anthropogenic Impact On Ballston Lake New York From A Short Core Using Stable Isotopes Of Carbon And Nitrogen And Trace Metals, Taylor S. Labrecque
Honors Theses
Ballston Lake occupies a portion of an avulsed channel of the Mohawk River between Schenectady and Saratoga Springs, New York. The lake is about 5 km long, generally less than 200m wide, ~8-15m deep, dimictic, with a catchment basin area of ~22km2. Long cores (>8 m) indicate that the lake formed ~13,000 cal yr BP. This study was undertaken to document recent environmental change recorded in the upper portion of sediment in Ballston Lake. Three sediment cores ~40 cm long were acquired from ~8 m water depth at the north end of Ballston Lake (42°57.101’N, 73°51.066’W), and were analyzed …
Old Father Hudson: The Three Stages Of Environmental Activism In The Hudson River Valley, Gregory P. Cannillo
Old Father Hudson: The Three Stages Of Environmental Activism In The Hudson River Valley, Gregory P. Cannillo
Honors Theses
Consequences of development have threatened the health of the Hudson River for decades. These have included the prospect of destroying scenic value of the Hudson River Valley with the a hydroelectric power plant on Storm King Mountain, as well as the pollution of the river itself by a variety of industrial sources. Since the 1960s, a long lineage of environmental activism in the Hudson River Valley has emerged to address those issues. The example of the Hudson River supplies an excellent case study of how environmental issues began to be addressed in the later half of the 20th century. I …
