Impact of a primary wastewater effluent of liver lipid metabolism and oxidative stress in St. Lawrence River Northern Pike

This study investigated the effect that municipal wastewater effluents (MWWEs) have on hepatic lipid metabolism and oxidative stress of Northern pike (Esox lucius) sampled both upstream and downstream of an effluent discharge location in the St. Lawrence River, at Montreal, Quebec, Canada from mid-June to mid-July 2022. Findings of this study suggest that chronic exposures to this fish may have sex-specific effects on liver lipid content and composition, as well as the transcription of genes involved in lipid metabolism. A manuscript detailing the methods, QA/QC, discussion, and conclusion based on these data has been submitted for peer review and will be published soon. The citation will be provided once available. Supplemental Information The St. Lawrence Action Plan (SLAP) 2011 to 2026 (see http://planstlaurent.qc.ca/en/home.html) is the latest Canada-Quebec Agreement on the St. Lawrence and builds on the four previous agreements implemented since 1988. The agreement aims to conserve and enhance the St. Lawrence. It is based on strong collaboration and the pooling of resources and expertise between the governments of Canada and Quebec. As part of their respective…
