The St. Lawrence River (SLR) is the second largest waterway in North America. The discharge of the City of Montreal wastewater treatment plant (WWTP) represents the largest volume of treated wastewaters being released into the river. It also ranks as the largest sewage treatment plant of its kind in North America. Over the last decade, intensive multidisciplinary research has focused on assessing the impacts of Montreal wastewater effluents on the SLR. We describe the major findings of these investigations, including the determination of the fate of contaminants, bioaccumulation in fish and invertebrates, ecotoxicological measurements of aquatic animal health, evaluation of endocrine disruption, parasitism in fish, and combined effects of multiple stressors on the SLR. Impacts of the effluents from the WWTP on aquatic organisms from the SLR are both toxicological and ecological, demonstrating the need for an integrated view of the impacts of municipal effluents on aquatic ecosystems.
圣劳伦斯河（SLR）是北美第二大水道。蒙特利尔市污水处理厂（WWTP）的排放量是排入该河的最大量经处理废水。它也是北美同类最大的污水处理厂。在过去十年中，密集的多学科研究聚焦于评估蒙特利尔废水排放对圣劳伦斯河的影响。我们描述了这些调查的主要发现，包括污染物的归宿测定、鱼类和无脊椎动物体内的生物累积、水生动物健康的生态毒理学测量、内分泌干扰评估、鱼类寄生虫以及多种压力源对圣劳伦斯河的综合影响。污水处理厂的废水对圣劳伦斯河水生生物的影响兼具毒理学和生态学性质，这表明需要对城市污水对水生生态系统的影响有一个综合的认识。
