Chemical and Toxicological Characterization of Dissolved Organics from Oil Sands Waters
(University of Waterloo, 2018-07-04)The surface mining of oil sands from the Athabasca deposit north of Fort McMurray, Alberta produces considerable tailings waste which is stored in large tailings ponds on industry lease sites. With the advent of oil sands ... -
Chronic Nickel and Copper Toxicity in the Hyalella azteca Cryptic Species Complex
(University of Waterloo, 2016-04-26)The amphipod crustacean Hyalella azteca was thought to be a single species, but recent molecular studies have indicated that it is a large cryptic species complex. Previous work has indicated that the H. azteca complex ... -
The Effects of Water Chemistry and Organism Source on Dysprosium Toxicity to Hyalella Azteca
(University of Waterloo, 2016-01-14)Rare earth elements (REEs) are a series of seventeen chemical elements, containing mostly lanthanides. Due to their multiple applications in industry and consumer electronics, global demand and production of REE has been ... -
Effects-Directed Analysis of Soluble Organics in Bitumen-Influenced Waters
(University of Waterloo, 2019-06-10)Identification of the organic compounds of concern within bitumen-influenced waters is critical for effective monitoring and reclamation within Canada’s oil sands region. Effects-directed analysis (EDA) is a tool used to ... -
Toxicity and bioaccumulation kinetics of cadmium and potassium permanganate in two clades within the 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 species complex
(University of Waterloo, 2019-09-12)The freshwater amphipod 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 has been frequently used in toxicology since the 1980s due to its general sensitivity, ease of culture, and North America-wide geographic range. Over the past 20 years, ... -
Use of Non-linear Models Based on Saturation Kinetics to Determine Chronic Co, Se or Zn Toxicity for Either Exposure or Body Burden in Hyalella azteca
(University of Waterloo, 2018-03-26)Water chemistry can influence the bioavailability, and therefore the toxicity, of metals and other elements. Water chemistry measurements have been incorporated into many water guidelines for the concentration of metals ...
