Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): McFarland, Victoria, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Metcalfe, Chris, Degree committee member (dgc): Hintelmann, Holger, Degree granting institution (dgg): Trent University
Abstract: <p>A catchment-based study was carried out at three remote acid sensitive Irish lakes to determine concentrations of Hg and POPs and to investigate the factors governing the partitioning of these pollutants in various environmental matrices. Both Hg and POPs are an environmental concern due to their ability to travel long distances via atmospheric transport and their tendency to accumulate… more

Name(s): Creator (cre): Hrynyk, Morgan Anne, Thesis advisor (ths): Metcalfe, Chris, Degree committee member (dgc): Kerr, Leslie, Degree committee member (dgc): Brunetti, Craig, Degree granting institution (dgg): Trent University
Abstract: <p>Exposure of pre-metamorphic amphibians to neonicotinoid insecticides may be contributing to the global decline in amphibian populations. In this study, anuran embryos and tadpoles of the African clawed frog (Xenopus laevis) and the North American leopard frog (Lithobates pipiens) were used to determine the effects of embryonic exposure to neonicotinoids. In addition, Xenopus was used to… 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
