Natural and anthropogenic inputs of arsenic and selenium to the environment in the Athabasca Bituminous Sands RegionDownload
Industrial development of the Athabasca Bituminous Sands (ABS) in northern Alberta, Canada, has raised concerns that emissions of arsenic and selenium to the surrounding landscape and waterbodies have been increasing over time. To test this hypothesis, a comprehensive study of arsenic and...

Background People with kidney failure are often deficient in zinc and selenium, but little is known about the optimal way to correct such deficiency. Methods We did a double-blind randomized trial evaluating the effects of zinc (Zn), selenium (Se) and vitamin E added to the standard oral renal...
Selenium is an essential trace element nutrient for human life, but it can be extremely toxic if taken excess. Various adsorbents have been applied for the removal of selenium from water but performed poorly in the removal of Se (VI), which is more bioavailable and more difficult to remove....
Arsenic is a potent environmental contaminant and human carcinogen, occurring naturally in the earth’s crust and entering the food chain through leeching into the water supply. Upon entering the body, inorganic arsenic is methylated to mono- and di-methylated forms, the trivalent versions of...
Water-Dispersible Magnetic Particle-Graphene Oxide Composites: Synthesis, Characterization and Application in the Removal of Selenium OxyanionsDownload
Selenium is toxic in excess with a high mobility in water. Existing adsorbents only show some removal capacity for selenite but perform poorly (typical removal percentage < 50 %) for selenate, the more bioavailable and soluble species. In this thesis, two Magnetic particle-Graphene Oxide...
Background Postpartum depression is a serious problem for women and their offspring. Micronutrient supplements are recommended for pregnant women because of their documented protective effects for the offspring, but their potential beneficial effects on maternal mental health are unknown. This...
The first chapter of this thesis describes the development of a general route for the generation of selenium stabilized carbanions via a method that bypasses acid catalyzed formation of selenoacetals. Aldehydes are first converted into α-hydroxystannanes by nucleophilic addition of Bu3SnLi. The...
I investigated, water, invertebrates and fishes from lakes in Banff National Park and Kananaskis Country, Alberta for selenium (Se), an element known to be toxic to vertebrates. At some depths, Se concentrations in sediment exceeded recognized thresholds for bird and fish reproductive...
Omega-3 polyunsaturated fatty acids (n-3 PUFA) enriched eggs are an increasingly important contributor to the egg industry due to the health benefits of n-3 PUFA. During storage and cooking, n-3 PUFA could undergo oxidation and further cause cholesterol oxidation. This study examined stability of...
