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，这就否定了这些生态系统所提供的服务。安大略省和加拿大作为一个整体拥有丰富的淡水资源，但这对维持、监测和保护这些资源构成了挑战。由于饮用水需求的增加，废水处理厂已经不堪重负，它们无法有效地去除现在进入我们饮用水的大量污染物。农药、工业化学品、药品和个人护理产品都进入了污水处理厂，但由于它们的化学成分复杂多样，很少有这些污染物得到有效处理，许多污染物畅通无阻地进入我们的水生态系统。这些污染物正在威胁加拿大的水生生态系统，并将危及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、保护和公园部(MECP)的任务是保护和监测安大略省广阔的水生生态系统。他们还被要求纳入现有的最佳科学和研究，以制定和提供政策、立法、法规、标准、方案和服务，以进行知情监测和环境保护。因此，拟议的伙伴关系旨在与MECP合作，开发一个新颖的综合分子水平平台，用于识别来自九个不同工业部门(发电、工业矿物、无机化学品、钢铁制造、金属铸造、采矿、有机化学品、石油以及纸浆和造纸)的废水中的可疑污染物、以前未记录的污染物及其对淡水模式生物(大型水蚤)的毒性。这一伙伴关系将使MECP拥有尖端科学知识，这些知识将被用来评估和推荐反映当今化学品排放的有效监管工具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，进而保护水生生态系统的环境和健康。
