Accumulation Of Polonium-210 In Different Species Of Fish In Lake Mead, Suraj Ghevarghese John, Shungmugam Nallaperumal, Vernon Hodge

Festival of Communities: UG Symposium (Posters)

Discovered by Pierre Curie and Marie Skłodowska-Curie in 1898, polonium is a chemical element with an atomic number of 84. This rare naturally occurring radioactive element is chemically similar to bismuth and tellurium, and forms in uranium ores. Polonium-210 is an naturally occurring radioactive element with a half-life of 138.376 days(1). This element is found in trace amounts in most organisms. Our research is focused on the accumulation of polonium-210 in fish that occupy in Lake Mead.

The sample species is chosen based on varying lake stratification (layers of the lake). This gives us a good idea of the difference …

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen

Lake Mead Science Symposium

Las Vegas Bay (LVB) of Lake Mead receives combined flows of tertiary treated wastewater effluent, urban runoff, and groundwater from the Las Vegas metropolitan area. This study examined the potential for endocrine disrupting effects of these anthropogenic inputs on male largemouth bass (Micropterus salmoides). Adult male bass were collected at two sites within Lake Mead: Overton Arm (OA, reference site), and Las Vegas Bay (LVB). Post-spawn fish were collected in July 2007 (n = 6-10 per site) and pre-spawn fish in March 2008 (n = 13 per site). Post-spawn fish were characterized by regressed testes whereas pre-spawn bass had full-grown …

Nuclear Technologies In The Great Basin Oral History Project, Danielle Endres

Native American Forum on Nuclear Issues

Abstract:

The United States currently faces a nuclear waste crisis. According to a 2002 report by former Secretary of Energy Spencer Abraham, “We have a staggering amount of radioactive waste in this country.”1 The Department of Energy (DOE) estimates that by 2035 the U.S. will have approximately 115,000 metric tons of high-level nuclear waste, which exceeds the capacity of the proposed federal storage site at Yucca Mountain.2 Deciding where and how to store nuclear waste is a significant nuclear, environmental, and health policy issue. The decisions that we make about nuclear waste siting greatly impact the future of nuclear technologies …

Session 7 - A Comparative Geographic Analysis Of The Impact Of Scale On Hazards And Vulnerability In Industrialized Continental Lands And Small Pacific Islands, William J. Smith Jr.

International Symposium on Technology and Society

Geography, specifically scale, has significant impacts in terms of hazards and vulnerability. Small islands, such as those found in the Pacific, experience the impacts of their relatively unique geography and scale in terms of hazards and vulnerability in at least five ways: 1) Perception and communication; 2) Impact and escape from impact; 3) Technology; 4) Recovery; and 5) Socio-environmental justice. Comparative analysis in these five areas between the Pacific’s small islands and industrialized continental regions illuminates differences regarding the way hazards and vulnerability should be conceptualized in the under-treated small islands of the world. Lessons from this analysis will aid …
