Radiologic sampling of surface soils near a USEPA superfund site

Creator:: Blakeman, Christopher John
Abstract:: The human health effects of acute exposure to high levels of ionizing radiation are well understood; however, when these irradiations occur at low levels, there is controversy as to their potential health threat (BEIR V, 1990). For individuals living in areas where the level of naturally occurring background radiation is...

Environmental Magnetism as a Proxy for Heavy Metal Concentrations at Formosa Mine Superfund Site

Creator:: Upton, Tullia L.
Abstract:: Environmental magnetic techniques have been used to discriminate sources of sediments from a variety of natural and anthropogenic sources. In many studies, magnetic properties such as susceptibility, have served as a proxy for heavy metal concentrations. In these cases, there tends to be enhancement of magnetic minerals. The study presented...

Creator:: Sethajintanin, Doolalai
Abstract:: Concentrations of twenty-five PCBs, fifteen organochiorine pesticides and mercury were determined in recreational fish from the Willamette River, Oregon during the summer of 2000. Thirty-six fish samples of three fish species including black crappie, smalimouth bass and con-rn-ion carp were analyzed. The data reported here provides new information and recent...

Identification, Quantification, and Risk Assessment of Polycyclic Aromatic Hydrocarbons and their Derivatives in Soil after Steam Enhanced Extraction

Creator:: Santiago Delgado, Lisandra
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants produced mainly from the incomplete combustion and pyrolysis of organic matter. PAHs are among the major contaminants at over 800 Superfund sites, nationwide. Thermal remediation is used as a method to remediate soils contaminated with PAHs through the use of heat to mobilize...

Contaminated communities : actively involved citizens, technical assistance, and the cleanup process

Creator:: Gaines, Lisa J.
Abstract:: In what is called participatory democracy scholars and practitioners have been calling for the involvement of citizens in decisions that affect their lives. Citizens who emerge to participate in technically complex, decision-making processes find that their involvement is often minimized, disregarded, or neglected due to barriers such as specialized scientific...

A characterization of early-summer terrestrial fauna and flora associated with acid mine drainage areas in the vicinity of Iron Mountain, Redding, California.

Creator:: Adamus, Paul R.
Abstract:: Surveys of flora and fauna were conducted in riparian areas of six streams in the general vicinity of the Iron Mountain mine near Redding, California. The surveys were intended to provide part of the information needed for a natural resource damage assessment (NRDA), should such an assessment be desired at...

Determining preliminary remediation goals for contaminated Hanford sites

Creator:: Hekkala, Darin R.
Abstract:: The Hanford nuclear reservation in Washington state was initially created during World War II for the production of plutonium to be used in atomic bombs. A perceived need for a large increase in the number of nuclear weapons spurred expansions in production facilities at Hanford through the 1960's, and production...

"Instead of tumbleweed, we have mitigation systems" : an ethnography of toxics risk, mitigation, and advocacy in IBM's deindustrialized birthplace

Creator:: Little, Peter C.
Abstract:: This dissertation draws on ethnographic data and political ecological theory to analyze the experience of residents living in the IBM-Endicott Superfund site in Endicott, New York. Combining in-depth narratives and quantitative measures from a household survey, it highlights residents' perceptions of 1) environmental health risk, 2) risk mitigation, 3) deindustrialization...

LncRNA regulation in mouse lung tumor from dibenzo[def,p]chrysene induced carcinogenesis in a transplacental Nrf2 knockout mouse model

Creator:: Patel, Karan, You, Hyekyoung, Siddens, Lisbeth, and Williams, David
Abstract:: Dibenzo[def,p]chrysene (DBC) is a highly potent, but less prevalent, environmental carcinogen belonging to a class of compounds known as Polycyclic Aromatic Hydrocarbons (PAHs). They are highly ubiquitous and arise as a byproduct of natural and anthropogenic combustion processes. Previous studies have documented carcinogenic effects upon in utero exposure of PAHs....

Identifying potential wetland restoration sites for estuary-wide restoration planning in Oregon : A pilot project in the Coos Estuary

Creator:: Fuss, J. David
Abstract:: Oregon's estuaries have been significantly altered by human activity, so that many former tidal wetlands no longer provide the functions, such as fish and wildlife habitat, erosion protection from storms, and water quality maintenance, that preserve the integrity of estuarine ecosystems. Oregon has been a leader in wetland protection and...

New Applications for Passive Samplers : In-situ Flux and Risk Assessment of Legacy and Emerging Contaminants

Creator:: Tidwell, Lane G.
Abstract:: Passive sampling devices (PSDs) were used to measure air vapor and water dissolved phase concentrations of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) at two different environmentally contaminated sites. Environmental contaminates like PAHs and OPAHs are present in both the atmospheric and aqueous environmental compartments. It is known that...

A study of residual Cesium 137 contamination in southwestern Utah soil following the nuclear weapons tests at the Nevada Test Site in the 1950's and 1960's

Creator:: Bentley, R. Blair
Abstract:: The Nevada Test Site (NTS) was the location for at least 100 above ground Nuclear Weapons tests during the 1950's and early 1960's. Radioactive fallout from these tests spread to many areas north and west of the NTS. According to estimates from the NCI and DOE, Washington County, Utah was...
