Plastic In The Pack: Assessing Microplastic Risk To Urban Coyotes (Canis Latrans) In The San Francisco Bay Area, Elaina E. Herrmann
Plastic In The Pack: Assessing Microplastic Risk To Urban Coyotes (Canis Latrans) In The San Francisco Bay Area, Elaina E. Herrmann
Master's Projects and Capstones
Microplastics are an emerging concern worldwide. However, their impact on terrestrial mammals, such as Canis latrans (coyotes), has yet to be extensively studied. Coyotes are unique in their ability to adapt to urban environments and have recently begun bridging the gap between marine and terrestrial food webs. This research examines the potential sources and impact of microplastic exposure in urban coyotes in the San Francisco Bay Area and possible food web impacts through literature synthesis and Geographic Information System (GIS) mapping. This research examined potential mechanisms for direct and trophic microplastic uptake by coyotes resulting from the anthropogenic, terrestrial, and …
Composting For Cleaner Air, Simi Benisty, Katie Bui, Narmin Solman, David Woo
Composting For Cleaner Air, Simi Benisty, Katie Bui, Narmin Solman, David Woo
Master's Projects and Capstones
The aim of this project was to address food waste at Mary's Kitchen by implementing a composting initiative to divert organic waste from landfills. The project took place in a nonprofit organization that serves food to the homeless, where the target population includes staff, volunteers, and clients of the kitchen. Key interventions involved creating educational materials on composting, recycling, and waste management, including flyers in both English and Spanish, as well as a QR code for easy access. Additionally, smaller, color-coded buckets were introduced to replace the 33-gallon bins, making waste sorting more manageable. Measures included staff and volunteer compliance …
Managing The Environmental And Socio-Economic Impacts Of Rohingya Refugees In Bangladesh, Mousume Azad
Managing The Environmental And Socio-Economic Impacts Of Rohingya Refugees In Bangladesh, Mousume Azad
Master's Projects and Capstones
In August 2017, nearly 1 million Rohingya people fled to Bangladesh to save their lives from the genocide inflicted by the military of Myanmar. At present, over 1.3 million Rohingyas are staying at Cox’s Bazar, Bangladesh, in 34 overcrowded refugee camps. This research examined the environmental impacts especially the change in vegetation cover and land surface temperature as well as the socioeconomic alteration of the host country after the refugee influx. The research found a 5488 ha or 9.58% decrease in forest area, accompanied by an 8.25% increase in refugee settlement areas, an increase in average land surface temperature within …
A Circular Economy Approach To Improve E-Waste Recycling In California: Economic Potential And Policy Options, Kripa Shah
Master's Projects and Capstones
The higher consumption rates of electronic devices along with their short life cycles and few repair options poses a huge challenge for E-waste industries to manage them effectively. E-waste comprises of hazardous materials and toxic constituents that can affect the environment and public health through improper disposal. However, they also contain few valuable materials that, if recovered, can reduce the dependence on virgin raw materials. Circular economy has the potential to utilize these valuable materials and gain environment and socio-economic benefits. The research explains how the adoption of a circular economy approach can help improve the E-waste recycling in California …
Addressing Uncertainties Of Polychlorinated Biphenyls In Schools, Alice Fan
Addressing Uncertainties Of Polychlorinated Biphenyls In Schools, Alice Fan
Master's Projects and Capstones
Despite the potential neurological health deficits resulting from polychlorinated biphenyls, there is a lack of inhalation studies and regulations to protect students and teachers who are widely exposed to PCBs in older (1950 to 1979) schools. To estimate the extent of PCB detections in Los Angeles County schools, I applied a mathematical model to estimate the range of PCB detections in schools built between 1950 and 1984. I estimate the range of 17-34% PCB detections of open schools within Los Angeles County. Next, I reviewed exposure tools provided by the US EPA to bridge the uncertainty gaps between ingestion and …
Policy Options To Mitigate Cigarette Filter Litter In California, Max Wechsler
Policy Options To Mitigate Cigarette Filter Litter In California, Max Wechsler
Master's Projects and Capstones
Approximately 16.2 billion cellulose acetate cigarette filters are littered in California annually. Cigarette filter litter (CFL) creates an annual financial burden of over $1.27 billion for California. CFL also poses unquantifiable damages to human and environmental health in the form of ingestion, toxicity, formation into microplastics, and quality of life degradation. These costs and damages warrant the adoption of policy measures in order to mitigate CFL. Cigarette taxes and fees raise government revenue, but they are politically challenging due to California Proposition 26. Locational smoking bans encourage anti-smoking cultural norms and may decrease consumption, although indoor smoking bans may increase …
A Geospatial Analysis Of Norovirus Outbreaks In California, And An Investigation Of The Impact Of Environmental Variables, Alexandra Groen
A Geospatial Analysis Of Norovirus Outbreaks In California, And An Investigation Of The Impact Of Environmental Variables, Alexandra Groen
Master's Projects and Capstones
Previous studies and empirical evidence suggest norovirus outbreaks in California exhibit correlation with environmental variables and exhibit spatial spread patterns. Few studies have been done looking at what causes norovirus seasonality in temperate climates and more research is needed on the regional level. This study aims to find what relationships exist with outbreak occurrence and environmental variables in California, as well as any spatial patterns of spread or clustering of outbreaks. Spatial analysis tools were used to find any relationships between California norovirus outbreak data and environmental variables. The results showed a south to north spread of outbreaks in California …
The Role Of Nitrogen And Phosphorus In The Growth, Toxicity, And Distribution Of The Toxic Cyanobacteria, Microcystis Aeruginosa, James Parrish
The Role Of Nitrogen And Phosphorus In The Growth, Toxicity, And Distribution Of The Toxic Cyanobacteria, Microcystis Aeruginosa, James Parrish
Master's Projects and Capstones
Microcystis aeruginosa is among the most common harmful algal-blooming species in the world. Potent microcystins released by M. aeruginosa have been linked to liver failure and death in aquatic mammals, like the endangered California sea otter, and provide a serious public health risk to humans. Once characterized as a freshwater problem, M. aeruginosa is expanding on a global scale, making persistent returns in freshwater, brackish, and coastal marine ecosystems. Though commonly observed dominating aquatic ecosystems in low N:P atomic ratios less than 44:1, the reliability of N:P ratios as a tool for managing and predicting M. aeruginosa blooms is explored …
