The long-term management of stored oil sands process-affected water (OSPW) is of concern due to the toxicity and persistence of OSPW organic fractions in the environment. To address the environmental issues associated with the recycling and/or safe discharge of the treated OSPW into the environment, new and innovative engineered water treatment technologies and approaches are required. The overall goal of the proposed Research Program is to conduct a comprehensive fundamental research in the area of oil sands tailings water treatment by using ozonation and advanced oxidation processes (AOPs) for the decontamination of OSPW and reduction of its toxicological impacts on mammals and aquatic species. The objectives of this Research Program include: (1) development of advanced analytical methods to characterize isomers and other organic species never identified before in OSPW; (2) development of a sequential multistep fractionation procedure of organic compounds present in OSPW to determine, for the first time, their compositional distribution patterns; (3) predictions of the reactivity of molecular ozone and radical species with different OSPW organic fractions through experimental and theoretical studies; (4) investigation of the effects of homogeneous ozonation and AOPs on the fate of different OSPW organic fractions; and (5) examination of the toxicological impacts of OSPW organic fractions, before and after treatment, on mammals and aquatic organisms. This Research Program will provide the fundamental engineering and scientific knowledge, leading to the environmentally sustainable development of the oil sands operations. In addition, the understanding of the fate of OSPW organic fractions together with the comprehensive analysis of the toxicological effects of OSPW on mammals and aquatic organisms may be directly linked to potential risks associated with OSPW exposures to humans and aquatic species, allowing government regulators to set guidelines for the protection of both the environment and public health. Moreover, the proposed Research Program will provide training of highly qualified personnel, with the finest educational opportunities in the area of oil sands tailings water treatment.

贮存油砂过程影响水（OSPW）的长期管理受到关注，因为OSPW有机组分在环境中的毒性和持久性。为了解决与回收和/或将处理后的OSPW安全排放到环境中相关的环境问题，需要新的和创新的工程水处理技术和方法。拟建研究项目的总体目标是在油砂尾矿水处理领域开展全面的基础研究，利用臭氧化和高级氧化工艺（AOPs）对OSPW进行净化，减少其对哺乳动物和水生物种的毒理学影响。本研究计划的目标包括：(1)发展先进的分析方法，以表征OSPW中从未发现过的异构体和其他有机物种；(2)开发了OSPW中存在的有机化合物的顺序多步分离程序，首次确定了它们的组成分布模式；(3)通过实验和理论研究预测分子臭氧和自由基与不同OSPW有机组分的反应性；(4)均匀臭氧化和AOPs对不同OSPW有机组分命运的影响；(5)检测OSPW有机组分在处理前后对哺乳动物和水生生物的毒理学影响。该研究项目将提供基本的工程和科学知识，引导油砂作业的环境可持续发展。此外，了解OSPW有机组分的命运以及对OSPW对哺乳动物和水生生物的毒理学影响的全面分析可能与与人类和水生物种接触OSPW相关的潜在风险直接相关，从而使政府监管机构能够制定保护环境和公众健康的指导方针。此外，拟议的研究方案将在油砂尾矿水处理领域提供训练高素质人员的最好的教育机会。
