Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Lock, Alan S., Thesis advisor (ths): Wallschläger, Dirk, Thesis advisor (ths): Belzile, Nelson, Degree committee member (dgc): Belzile, Nelson, Degree committee member (dgc): Gueguen, Celine, Degree granting institution (dgg): Trent University
Abstract: <p>A bedrock fracture hosting arsenic (As) contaminated groundwater was suspected to be transported to Ramsey Lake, a drinking water resource for more than 50,000 residents of Sudbury, Ontario. A high resolution, spatial, water quality mapping technique using an underwater towed vehicle (UTV) was used to identify sources of upwelling groundwater into lake water and localize the upwelling As… more

The effects of Dissolved Organic Matter (DOM) sources on Pb2+, Zn2+ and Cd2+ binding

Name(s): Creator (cre): Chen, Weibin, Thesis advisor (ths): Gueguen, Celine, Thesis advisor (ths): Smith, Scott, Degree committee member (dgc): McGeer, James, Degree granting institution (dgg): Trent University
Abstract: <p>Metal binding to dissolved organic matter (DOM) determines metal speciation and strongly influences potential toxicity. The understanding of this process, however, is challenged by DOM source variation, which is not always considered by most existing metal speciation models. Source determines the molecular structure of DOM, including metal binding functional groups. This study has… more

Detecting anti-estrogens and anti-androgens in surface waters impacted by municipal wastewater discharges and agricultural runoff

Name(s): Creator (cre): Corcoran, Shawna Karen Jackson, Thesis advisor (ths): Metcalfe, Chris, Degree committee member (dgc): Ellis, David, Degree committee member (dgc): Gueguen, Celine, Degree granting institution (dgg): Trent University
Abstract: <p>This study focused on detecting 22 target anti-estrogenic and anti-androgenic compounds in surface waters influenced by both discharges of municipal wastewater and agricultural runoff in Canada and Argentina. Polar organic chemical integrative samplers (POCIS) were used to monitor the target compounds in surface waters. The removals of the target compounds in a municipal wastewater… more

Chemical characterization of dissolved organic matter in relation with hydrography in the Arctic Ocean

Name(s): Creator (cre): Gao, Zhiyuan, Thesis advisor (ths): Gueguen, Celine, Degree committee member (dgc): Ellis, David, Degree committee member (dgc): Lafleur, Peter, Degree granting institution (dgg): Trent University
Abstract: <p>In this thesis, water mass distribution of dissolved organic matter (DOM) characteristics (i.e. molecular weight, fluorescent components, thiols and humic substances concentration) was observed in the Arctic Ocean. For the first time, DOM molecular weight (MW) in Beaufort Sea was assessed using asymmetrical flow field-flow fractionation, as well as the first monitoring of thiols and… more
