Creator:: Bergmann, Alan J.
Abstract:: Assessing the risk from exposure to a chemical mixture in the environment can seem prohibitively challenging. Most components of the mixture are not readily identifiable, chemicals may interact to cause other-than-additive toxicity, and the number of potential combinations of environmental contaminants is enormous. These challenges can make it seem impossible...

Creator:: Samon, Samantha M.
Abstract:: Exposure assessment is necessary to determine the frequency and magnitude of environmental contaminants, especially since exposure may lead to adverse health outcomes. Traditional personal exposure assessment tools such as biological samples are limited in their ability to capture a wide range of chemical exposures from a single sample, and others...

Creator:: Dixon, Holly M.
Abstract:: Silicone wristbands are easy-to-wear passive samplers that have been readily adapted into environmental health studies since first reported in 2014. Wristbands can be worn during normal daily activities and sequester a wide range of bioavailable organic chemicals. This dissertation includes a thorough review of silicone wristband technology, as well as...

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...

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:: Donald, Carey E.
Abstract:: Passive sampling devices have been used for decades to measure complex mixtures of bioavailable organic chemicals in a variety of environmental media. More recently passive sampler applications have expanded beyond monitoring chemical concentrations, and this dissertation continues to advance methods of passive sampling on many fronts. Despite their growing use,...

Creator:: Rivera, Brianna N.
Abstract:: Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...
