Implications of copper and nickel exposure to different members of the Hyalella azteca species complex
(University of Waterloo, 2014-04-25)Hyalella azteca, an amphipod crustacean, is frequently used in freshwater toxicity tests. Since the mid-1980s, numerous organizations have collected and established cultures of H. azteca originating from localities across ... -
Metal Mixture Toxicity to Hyalella azteca: Relationships to Body Concentrations
(University of Waterloo, 2008-01-25)A literature review of metal mixture interaction analyses identified that there was not a consistent method to determine the impact of metal mixtures on an aquatic organism. The review also revealed that a majority of the ... -
Molecular Biogeography of the Amphipod Genus Hyalella in North America
(University of Waterloo, 2016-04-18)Hyalella azteca (order: amphipoda) was once thought to be one of the most broadly distributed North America freshwater crustaceans, but recent molecular studies have discovered several species belonging to a morphologically ... -
Photoinduced Toxicity of Metals and PAHs to Hyalella azteca: UV-Mediated Toxicity and the Effects of Their Photoproducts
(University of Waterloo, 2009-05-08)Polycyclic aromatic hydrocarbons (PAH) are a class of common environmental contaminants known to be phototoxic. PAH Photoinduced toxicity is caused by two mechanisms: photomodification and photosensitization. The ... -
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, ... -
Toxicity and bioaccumulation of sediment-associated metals and elements from wildfire impacted streams of southern Alberta on Hyalella azteca
(University of Waterloo, 2013-10-02)There is increasing global recognition of the effects of large scale land disturbance by wildfire on a wide range of water and ecosystem services. In 2003, the Lost Creek wildfire burned a contiguous area of 21,000 ha on ... -
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 ...
