Name(s): Creator (cre): Zhu, Yu, Thesis advisor (ths): Gueguen, Celine, Degree committee member (dgc): Koprivnjak, Jean-François, Degree committee member (dgc): Aherne, Julian, Degree granting institution (dgg): Trent University
Abstract: <p>This study assesses the bioavailable metal (Cu, Ni, Zn, Pb) species in the Athabasca-Mackenzie watersheds using diffusive gradient in thin films (DGT) devices. Metal toxicity is not only based on the concentration of metal in natural waters, but also on the nature of metal species. Four main forms in aquatic systems are: free ion, inorganic species, DOM bound (humic) species and metal… more

Bioremoval of copper and nickel on living and non-living Eugelna gracilis

Name(s): Creator (cre): Winters, Cameron, Thesis advisor (ths): Gueguen, Celine, Degree committee member (dgc): Sager, Eric, Degree committee member (dgc): Emery, Neil, Degree granting institution (dgg): Trent University
Abstract: <p>This study assesses the ability of a unicellular protist, Euglena gracilis, to remove Cu and Ni from solution in mono- and bi-metallic systems. Living Euglena cells and non-living Euglena biomass were examined for their capacity to sorb metal ions. Adsorption isotherms were used in batch systems to describe the kinetic and equilibrium characteristics of metal removal. In living systems… more

Relationships between Dissolved Organic Matter and Vanadium Speciation in the Churchill River, MB and the Mackenzie River Basin, NWT using diffusive gradients in thin films (DGT)

Name(s): Creator (cre): Shi, Yong Xiang, Thesis advisor (ths): Gueguen, Celine, Degree committee member (dgc): Newman, Karla, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
Abstract: <p>This study examines the influence of dissolved organic matter (DOM) on dissolved vanadium (V) speciation in the Churchill River and Great Slave Lake using diffusive gradients in thin film (DGT). Vanadium is commonly found in natural environments such as rivers, lakes and oceans. It regulates normal cell growth, but in excessive amounts, it can have toxic effects on human and aquatic… more
