Abstract: <p>Radionuclides occur in the environment both naturally and artificially. Along with weapons testing and nuclear reactor operations, activities such as mining, fuel fabrication and fuel reprocessing are also major contributors to nuclear waste in the environment. In terms of nuclear safety, the concentration of radionuclides in nuclear waste must be monitored and reported before storage… more

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
