Surface mining of bitumen from the oil sands region in northern Alberta uses an extraction process that results in the accumulation of large volumes of oil sands process-affected water (OSPW) that is stored in tailings ponds. In addition to salts, heavy metals, and inorganic compounds, OSPW contains a complex mixture of organic compounds often loosely referred to as 'naphthenic acids' (NAs) that are toxic to living organisms. OSPW cannot be released into the environment until the toxicity is reduced to acceptable levels. The oil sands mining industry has identified the NA component as a primary target for OSPW remediation, and is focused on developing passive, low-input OSPW remediation approaches.This proposal describes research aimed at determining the capacity of selected upland plant species to remediate NAs from OSPW in an irrigated soil environment. This passive, plant-based approach represents a low-input, green technology that could be implemented alongside other established and developing remediation approaches used in the oil sands mining industry. It takes advantage of the advanced metabolic capacity of plants and associated microbes to remediate soils. This novel biotechnology aligns with the passive remediation goals of the oil sands mining industry, and has the potential to treat millions of cubic meters of OSPW annually. Successful implementation of this biotechnology could assist in meeting the NA remediation goals of oil sands mining companies, and will strengthen the reputation of the industry as an environmentally responsible contributor to the Canadian economy. This research spans the fields of biochemistry, plant ecophysiology, land reclamation and aspects of mining engineering. Thus, it will support and develop the training of Canada's future leaders in green technology solutions, and create new jobs in the clean growth of Canada's oil sands industry as well as advanced biotechnology sector.

艾伯塔省北部油砂地区的沥青露天开采采用的提取工艺会导致大量受油砂工艺影响的水 (OSPW) 积聚，并储存在尾矿池中。除了盐、重金属和无机化合物外，OSPW 还含有有机化合物的复杂混合物，通常被笼统地称为“环烷酸”(NA)，对生物体有毒。 OSPW 在毒性降低到可接受的水平之前不能释放到环境中。油砂采矿业已将 NA 成分确定为 OSPW 修复的主要目标，并专注于开发被动、低投入的 OSPW 修复方法。该提案描述了旨在确定选定高地植物物种修复 NA 的能力的研究。灌溉土壤环境中的 OSPW。这种被动的、基于植物的方法代表了一种低投入的绿色技术，可以与油砂采矿业中使用的其他已建立和正在开发的修复方法一起实施。它利用植物和相关微生物的先进代谢能力来修复土壤。这种新颖的生物技术符合油砂采矿业的被动修复目标，有潜力每年处理数百万立方米的 OSPW。该生物技术的成功实施可以帮助实现油砂开采公司的 NA 修复目标，并将加强该行业作为加拿大经济对环境负责的贡献者的声誉。这项研究涵盖生物化学、植物生态生理学、土地复垦和采矿工程方面的领域。因此，它将支持和发展加拿大未来绿色技术解决方案领导者的培训，并在加拿大油砂行业和先进生物技术领域的清洁增长中创造新的就业机会。
