Aqueous speciation of selenium during its uptake by green algae Chlamydomonas reinhardtii
(University of Waterloo, 2013-05-03)Selenium (Se) is a micronutrient, yet elevated Se can be toxic to aquatic organisms. The range of Se concentrations within which Se uptake goes from insufficient to toxic is very narrow. It is thus important to understand ... -
Development of an endothelial-like cell line from the brain of the American eel and its use to study the effects of selenium
(University of Waterloo, 2017-02-14)A cell line, eelB, has been developed in this thesis from the brain of the American eel, Anguilla rostrata (Lesueur), an endangered species and belonging to a group of fish that for unknown reasons appear to be in worldwide ... -
Development of Photocatalytic Materials and Systems for the Removal of Selenium from Industrially Impacted Water
(University of Waterloo, 2019-04-17)Selenium (Se) contaminated water derived from global industrial activities such as power generation, oil extraction and refining, coal and mineral mining, metal smelting, and agricultural irrigation can bioaccumulate in ... -
Fish Consumption and Mercury Exposures Among Sub-populations in Canada through Targeted Biomonitoring: Results from Dene/Métis Communities of the Northwest Territories and a Maternal-Infant Cohort Study
(University of Waterloo, 2023-08-02)Fish contain many important nutrients including omega-3 polyunsaturated fatty acids (PUFA) (such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) and essential elements (such as selenium (Se)), and fish ... -
Hybrid Amorphous Selenium-CMOS Photon-Counting X-ray Imager
(University of Waterloo, 2018-05-23)Many medical imaging modalities, such as mammography and micro-computed tomography, utilize digital X-ray imagers to observe human anatomy. Direct digital X-ray imagers rely on a sensor layer (typically a photoconductor) ... -
Integrating Methods for Characterizing the Passive Treatment of Mercury and Selenium in Groundwater and Sediment
(University of Waterloo, 2011-03-16)Standard geochemical analysis methods, such as aqueous geochemistry analysis and mineralogical analysis, frequently are utilized to evaluate the effectiveness of passive treatment systems, though they do not necessarily ... -
Integration of non-traditional stable isotopes and synchrotron measurements
(University of Waterloo, 2022-08-31)Selenium is well named after the moon, because statements about this element must often be qualified, making it feel ever changing; for instance, Se is a nutrient, but an excess of 400 µg per day is toxic for humans. High ... -
Selenate Reduction by Granular Iron and the Associated Isotope Fractionation
(University of Waterloo, 2013-11-27)Research in selenium isotopes has been gaining interest as new contaminated sites are identified around the world. Selenium is an emerging contaminant, as it is increasingly being released through anthropogenic activities. ...
