Creator:: Hillwalker, Wendy E.
Abstract:: Concentrations of selenium (Se), manganese (Mn), zinc (Zn), cadmium (Cd), lead (Pb) and arsenic (As) were measured in the water column, sediment and biota, in conjunction with selected physicochemical data, from representative wetland types at a mining site within Salt Lake County, Utah, USA. The selected field sites included Oolitic...

Creator:: Quarles, Lucas W.
Abstract:: Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely...

Creator:: Forsberg, Norman D.
Abstract:: Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...

Creator:: Allan, Sarah E.
Abstract:: Chemicals must be bioavailable for there to be a potential for exposure and consequent risk to human or environmental health. Passive sampling devices (PSDs) are used to quantify the time-integrated concentration of bioavailable contaminants. We demonstrate that PSDs can be paired with the zebrafish developmental toxicity bioassay to produce site-specific,...

Creator:: Pérez, Angela L.
Abstract:: Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...

Creator:: Sethajintanin, Doolalai
Abstract:: The seasonal distribution of bioavailable organochiorine contaminants in surface water and the potential environmental factors influencing their bioavailability were evaluated. The study was carried at the lower Willamette River at Portland Harbor, Oregon where surface water runoff varied according to season. Bioavailable water concentrations of DDTs and PCBs were determined...
