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:: Layshock, Julie
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) with a molecular weight (MW) of 302 and oxygenated-PAHs (OPAHs) have demonstrated toxicity beyond that of frequently monitored and known carcinogenic PAHs. Airborne particulate matter (PM) was characterized for MW 302 isomers to evaluate risk and air quality indices and OPAHs in order to fill data...

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:: 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:: 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...
