Widespread use of perfluorooctane surfactants has led to ubiquitous presence of these chemicals in biological tissues. While perfluorooctane surfactants have been measured in blood and liver tissue samples of fish, birds, and mammals in the Great Lakes region, data for the aqueous concentrations of these compounds in the Great Lakes or other ambient waters(More)
The origin and amount of perfluorooctane surfactants in wastewater treatment systems, and the transformation these compounds may undergo during treatment, were evaluated through measurement and experiment. Influent, effluent, and river water at the point of discharge for a 6-MGD wastewater treatment plant (WWTP) were screened for eight perfluorooctane(More)
Perfluorooctane surfactants have been reported in biota, water, and air samples worldwide. Despite these reports, the main environmental sources of these compounds remain undefined. To address this gap in knowledge, an annual lake-wide mass budget of eight perfluorooctane surfactants was developed for Lake Ontario. To determine the atmospheric contribution(More)
Healthcare facilities are an under-characterized source of pharmaceuticals to municipal wastewaters. In this study, the composition and magnitude of sixteen cardiovascular active pharmaceutical ingredients (APIs) and two cardiovascular API metabolites in wastewater effluents from a hospital, nursing care, assisted living, and independent living facility are(More)

Alkylphenols and alkylphenol ethoxylates are ubiquitous wastewater contaminants. In this study the oxidation of nonylphenol ethoxylates (NPEO) and octylphenol ethoxylates (OPEO) by oxidant systems generating hydroxide radicals was evaluated. The reaction of each oxidant with a technical mixture of NPEO (Tergitol™) and OPEO (Triton X-100™) in ultrapure(More)
Nervous system active pharmaceutical ingredients (APIs), including anti-depressants and opioids, are important clinically administered pharmaceuticals within healthcare facilities. This study provides source characterization data describing the composition and magnitude of nervous system APIs present in healthcare facility wastewaters. Concentrations and(More)
Healthcare facility wastewaters are an anticipated source of known endocrine disrupting chemicals to the environment. In this study, the composition and magnitude of eight steroid hormones, octylphenol (OP), nonylphenol (NP), 16 nonylphenol ethoxylates (NPEOs), and 10 octylphenol ethoxylates (OPEOs) in wastewater from a(n) hospital, nursing facility,(More)
Six commonly occurring polychlorinated biphenyl congeners (PCB28, PCB52, PCB101, PCB138, PCB153 and PCB180) were measured in water, surface sediments, and sediment core samples from 10 monitoring stations across Dianchi Lake in Kunming, China to determine the distributions, historical trends, and sources of PCBs to this ecologically and regionally important(More)
