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
Ussery, Erin J.; McMaster, Mark E.; Servos, Mark. R.; Miller, David H.; Munkittrick, Kelly R. (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 ... -
An Assessment of the Spatial and Temporal Variability of Biological Responses to Municipal Wastewater Effluent in Rainbow Darter (Etheostoma caeruleum) Collected along an Urban Gradient
Fuzzen, Meghan; Bragg, Leslie M.; Tetreault, Gerald R.; Bahamonde, Paulina; Tanna, Rajiv N.; Bennett, Charles J.; McMaster, Mark E.; Servos, Mark R. (PLOS, 2016-10-24)Municipal wastewater effluent (MWWE) and its constituents, such as chemicals of emerging concern, pose a potential threat to the sustainability of fish populations by disrupting key endocrine functions in aquatic organisms. ... -
Characterizing Transcriptional Networks in Male Rainbow Darter (Etheostoma caeruleum) that Regulate Testis Development over a Complete Reproductive Cycle
Bahamonde, Paulina; McMaster, Mark E.; Servos, Mark R.; Martyniuk, Christopher J.; Munkittrick, Kelly R. (PLOS, 2016-11-18)Intersex is a condition that has been associated with exposure to sewage effluents in male rainbow darter (Etheostoma caeruleum). To better understand changes in the transcriptome that are associated with intersex, we ... -
Endocrine Disruptor Impacts on Fish From Chile: The Influence of Wastewaters
Barra, Ricardo O.; Chiang, Gustavo; Saavedra, Maria Fernanda; Orrego, Rodrigo; Servos, Mark. R.; Hewitt, L. Mark; McMaster, Mark E.; Bahamonde, Paulina; Tucca Díaz, Felipe; Munkittrick, Kelly R. (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 ... -
Reduction of intersex in a wild fish population in response to major municipal wastewater treatment plant upgrades
Hicks, Keegan A.; Fuzzen, Meghan; McCann, Emily K.; Arlos, Maricor J.; Bragg, Leslie M.; Kleywegt, Sonya; Tetreault, Gerald R.; McMaster, Mark E.; Servos, Mark. R. (American Chemical Society, 2017)Intersex in fish downstream of municipal wastewater treatment plants (MWWTPs) is a global concern. Consistent high rates of intersex in male rainbow darter (Etheostoma caeruleum) have been reported for several years in the ...
