Use of prospective and retrospective risk assessment methods that simplify chemical mixtures associated with treated domestic wastewater discharges
(Wiley, 2018-03-01)A framework is presented that is intended to facilitate the evaluation of potential aquatic ecological risks resulting from discharges of down-the-drain chemicals. A scenario is presented using representatives of many of ... -
Tissue storage affects lipidome profiling in comparison to in vivo microsampling approach
(Springer, 2018-05-03)Low-invasive in vivo solid-phase microextraction (SPME) was used to investigate the lipid profiles of muscle tissue of living fish. Briefly, mixed mode SPME fibers were inserted into the muscle for 20 min extraction, and ... -
Multiple Stressors in the Environment: The Effects of Exposure to an Antidepressant (Venlafaxine) and Increased Temperature on Zebrafish Metabolism
(Multidisciplinary Digital Publishing Institute, 2019-11-19)Aquatic organisms are continuously exposed to multiple environmental stressors working cumulatively to alter ecosystems. Wastewater-dominated environments are often riddled by a myriad of stressors, such as chemical and ... -
Impacts on Metabolism and Gill Physiology of Darter Species (Etheostoma spp.) That Are Attributed to Wastewater Effluent in the Grand River
(Multidisciplinary Digital Publishing Institute, 2020-11-25)The effluent from municipal wastewater treatment plants is a major point source of contamination in Canadian waterways. The improvement of effluent quality to reduce contaminants, such as pharmaceuticals and personal care ... -
Photocatalytic Degradation of Microcystins by TiO2 Using UV-LED Controlled Periodic Illumination
(Multidisciplinary Digital Publishing Institute, 2019-02-14)Toxic microcystins (MCs) produced by freshwater cyanobacteria such as Microcystis aeruginosa are of concern because of their negative health and economic impacts globally. An advanced oxidation process using UV/TiO2 offers ... -
High Throughput Sequencing of MicroRNA in Rainbow Trout Plasma, Mucus, and Surrounding Water Following Acute Stress
(Frontiers, 2021-01-13)Circulating plasma microRNAs (miRNAs) are well established as biomarkers of several diseases in humans and have recently been used as indicators of environmental exposures in fish. However, the role of plasma miRNAs in ... -
Endocrine Disruptor Impacts on Fish From Chile: The Influence of Wastewaters
(Frontiers, 2021-03-25)Industrial wastewaters and urban discharges contain complex mixtures of chemicals capable of impacting reproductive performance in freshwater fish, called endocrine-disrupting compounds (EDCs). In Chile, the issue was ... -
A 30-Year Study of Impacts, Recovery, and Development of Critical Effect Sizes for Endocrine Disruption in White Sucker (Catostomus commersonii) Exposed to Bleached-Kraft Pulp Mill Effluent at Jackfish Bay, Ontario, Canada
(Frontiers, 2021-04-22)Jackfish Bay is an isolated bay on the north shore of Lake Superior, Canada that has received effluent from a large bleached-kraft pulp mill since the 1940s. Studies conducted in the late 1980s found evidence of reductions ... -
Effect of Background Water Matrices on Pharmaceutical and Personal Care Product Removal by UV-LED/TiO2
(Multidisciplinary Digital Publishing Institute, 2021-04-30)In this study, we evaluated the effectiveness of UV-LED-irradiated TiO2 in removing 24 commonly detected PPCPs in two water matrices (municipal wastewater effluent and Suwannee River NOM–synthetic water) and compared their ... -
Biological responses in fish exposed to municipal wastewater treatment plant effluent in situ
(IWA Publishing, 2021-04-16)Effluents from municipal wastewater treatment plants (MWTPs) are complex mixtures of chemicals including endocrine-disrupting compounds (EDCs) and 17α-ethynylestradiol (EE2). The objective of this study was to evaluate ... -
Contrasting physiological responses between invasive sea lamprey and non-target bluegill in response to acute lampricide exposure
(Elsevier, 2021-08-01)Control of invasive sea lamprey (Petromyzon marinus) in the Laurentian Great Lakes of North America uses lampricides, which consist of 3-trifluoromethyl-4-nitrophenol (TFM) and niclosamide. Lampricides are thought to inhibit ... -
The Role of Wastewater Testing for SARS-CoV-2 Surveillance
(Ontario COVID-19 Science Advisory Table, 2021-08-26)Wastewater testing for SARS-CoV-2 is relatively new; however, it builds on existing public health surveillance infrastructure. There is a limited but growing evidence base for its use, despite notable interpretation ... -
