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 …

Scan Of The Advantage Of Using Biofuels, Ethanol, Ana Carla Bueno

Symposium of Student Scholars

The environment is the big sink where all the human waste produced is deposited, mainly the pollutant gases from cars. It is inevitable not to contaminate drinking water, air, and all other ecosystems on the planet, and it was from these concerns that scientists began to develop alternative ways to mitigate the side effects of pollution. Currently, there are many strategies to soften the emission of pollutant gases into the atmosphere, and the biggest competitor of traditional fossil fuel is biofuels. The big challenge in the production of this type of fuel is the competition with the conventional fossil fuel, …

The ever-changing regulatory and federal standards set by the EPA and other organizations are creating a large impact on chemical manufacturing. The Environmental Protection Agency (EPA) maintains jurisdiction under the Toxic Substances Control Act (TSCA) to enforce regulations structured to impart information regarding the health and safety of individuals, environmental impacts, and exposure thresholds of chemical substances. Flame retardants are among the chemicals assessed and restricted, most recently isopropyl phenyl phosphate. Isopropyl phenyl phosphate is a flame retardant/lubricant utilized in various …

Records Of Enriched Uranium Atmospheric Deposition In Pond Sediments In Piketon, Oh, Brianna Herner, Brian Majestic, Michael Ketterer

DU Undergraduate Research Journal Archive

The enrichment of uranium, often for nuclear weapons programs and commercial nuclear reactors, produces higher concentrations of radioactive uranium 235 (²³⁵U) than what naturally occurs, which can pose a human health hazard. The most abundant naturally occurring uranium isotope is ²³⁸U, which is still radioactive, however a higher concentration of ²³⁵U skews the observed isotopic uranium distribution. The Department of Energy Portsmouth Gaseous Diffusion Plant, located near Piketon, OH, enriched uranium from 1954 to 2001 and ²³⁵U pollution has recently been detected in air and sediment samples in the surrounding community. The extent of the …
