Identification and Quantification of Organic Selenium Species Produced by Microbiological Activity in Freshwater Environments

22148-Thumbnail Image.png
Year: 2016, 2016
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): LeBlanc, Kelly Lynn, Thesis advisor (ths): Wallschlaeger, Dirk, Degree committee member (dgc): Evans, R. Douglas, Degree committee member (dgc): Belzile, Nelson, Degree granting institution (dgg): Trent University
Abstract: <p>Despite being an essential nutrient at trace levels, selenium can be devastating to aquatic environments when present in excess. There is no apparent correlation between total aqueous selenium concentrations and observed toxic effects because bioaccumulation varies over several orders of magnitude depending on the chemical species of selenium and the biological species present in the… more

Fractionation of Mercury Isotopes in an Aqueous Environment: Chemical Oxidation

Name(s): Creator (cre): Stathopoulos, Dimitri, Thesis advisor (ths): Hintelmann, Holger, Degree committee member (dgc): Wallschlaeger, Dirk, Degree committee member (dgc): Evans, Douglas, Degree granting institution (dgg): Trent University
Abstract: <p><bold>Fractionation of mercury isotopes in an aqueous environment: Chemical Oxidation</bold></p><p><italic>Dimitri Stathopoulos</italic></p><p>The study of fractionation patterns for the stable isotopes of mercury is a growing field. The potential for stable isotopes to trace mercury through the environment from pollution sources to sinks… more

Analysis and reactions of aqueous selenide and other reduced inorganic selenium compounds under anoxic conditions

Name(s): Creator (cre): Smith, Matthew, Thesis advisor (ths): Wallschlaeger, Dirk, Degree committee member (dgc): Dillon, Peter, Degree committee member (dgc): Belzile, Nelson, Degree committee member (dgc): Gueguen, Celine, Degree granting institution (dgg): Trent University
Abstract: <p>Selenide is cited as a geochemically important selenium (Se) species, but it is unknown whether selenide is a stable aqueous ion in natural waters. The feasibility of using anoxic anion exchange chromatography (AEC) coupled to dynamic reaction cell-inductively coupled plasma-mass spectrometry to separate aqueous selenide was investigated with the goal of quantifying this anion to… more
