Aquatic ecosystems around the world are experiencing declines in water quality and health which then negate the services that these ecosystems provide. Ontario and Canada as a whole, have vast freshwater resources but this poses a challenge with respect to sustaining, monitoring, and protecting these resources. Wastewater treatment plants, already overwhelmed due to the increased demand for drinking water, cannot efficiently remove the multitude of pollutants that now enter our drinking water. Pesticides, industrial chemicals, pharmaceuticals and personal care products all enter wastewater treatment plants, but due to their complex and diverse chemistry, few of these pollutants are treated effectively and many enter our aquatic ecosystems unimpeded. These contaminants are threatening Canada's aquatic ecosystems and will jeopardize the long-term sustainability of drinking water and related aquatic ecosystem services. Ontario's Ministry of the Environment, Conservation, and Parks (MECP) is tasked with protecting and monitoring Ontario's vast aquatic ecosystems. They are also required to incorporate the best available science and research to develop and deliver policies, legislation, regulations, standards, programs and services for informed monitoring and environmental protection. As such, the proposed partnership aims to develop a novel and integrated molecular-level platform for the identification of suspected pollutants, previously undocumented pollutants and their respective toxicity to a freshwater model organism (Daphnia magna) in wastewater effluents from nine different industrial sectors (electric power generation, industrial minerals, inorganic chemicals, iron and steel manufacturing, metal casting, mining, organic chemicals, petroleum, and pulp and paper) in collaboration with the MECP. This partnership will equip the MECP with cutting-edge scientific knowledge that will be used to evaluate and recommend effective regulatory tools that reflect present day chemical releases and molecular-level tools for environmental monitoring. These tools will improve environmental monitoring programs in Ontario and Canada which will in turn protect the environmental and health of aquatic ecosystems.

世界各地的水生生态系统正在经历水质和健康的下降，然后消除了这些生态系统提供的服务。 整个安大略省和加拿大拥有丰富的淡水资源，但这在维持，监视和保护这些资源方面构成了挑战。由于对饮用水的需求增加，废水处理厂已经不知所措，无法有效去除现在进入我们饮用水的众多污染物。农药，工业化学物质，药品和个人护理产品均进入废水处理厂，但是由于其复杂而多样的化学作用，这些污染物中的几乎没有有效治疗，许多污染物未经阻碍地进入我们的水生生态系统。 这些污染物正在威胁加拿大的水生生态系统，并将危害饮用水和相关水生生态系统服务的长期可持续性。安大略省环境，保护和公园（MECP）的任务是保护和监视安大略省庞大的水生生态系统。 他们还必须纳入最佳的科学和研究，以制定和提供政策，立法，法规，标准，计划和服务，以进行知情监测和环境保护。 因此，提出的伙伴关系旨在开发一个新颖而综合的分子级平台，以鉴定可疑的污染物，以前是无证件的污染物，及其对淡水模型生物体（Daphnia magna）的毒性，在废水中的淡水模型生物体（Daphnia magna）中与MECP合作的化学物质，石油和纸浆和纸张）。 该合作伙伴关系将使MECP拥有最先进的科学知识，该知识将用于评估和推荐有效的监管工具，以反映当今的化学释放和用于环境监测的分子级工具。 这些工具将改善安大略省和加拿大的环境监测计划，反过来又可以保护水生生态系统的环境和健康。
