Naphthenic acids (NAs) represent the primary source of acute toxicity and endocrine disrupting potential refinery wastewater and oil sands process-affected water (OSPW). There is a growing concern over NAs seepage into surrounding surface and groundwater, and subsequent adverse impact on aquatic ecosystem and environment. Thus, routine monitoring of NAs in these wastewaters are crucial for oil sands industry. Existing analytical methods used for analysis of NAs in water samples are time-consuming and expensive, and samples need to be sent to an analytical laboratory. Hence, development of a low-cost and fast analytical method for monitoring of NAs will help to address these challenges. A recent research program carried out at the University of Alberta in collaboration with Imperial Oil Resources Limited showed that microbial fuel cell (MFC) based biosensor could provide an efficient and cost-effective method for monitoring NAs in water samples. This proposal addresses the challenges that have to be overcome to develop this MFC biosensor for field application. The scope of the project includes understanding interactions among various NAs, the effect of various environmental parameters, long-term demonstration studies for detection of NAs in real process water, and development of a miniaturized biosensor. It is anticipated that this two-year project will culminate in the development of a robust MFC biosensor that can be used for on-site quantification or in-situ monitoring of NAs by oil sands industry, thereby ensuring sustainable environmental management in the oil sands mining operation.

环烷酸 (NA) 是潜在的急性毒性和内分泌干扰的炼油厂废水和油砂工艺影响水 (OSPW) 的主要来源。人们越来越担心NAs渗入周围地表和地下水，以及随后对水生生态系统和环境的不利影响。因此，对这些废水中的NA进行常规监测对于油砂工业至关重要。 现有的用于分析水样中的NA的分析方法既耗时又昂贵，并且需要将样品送到分析实验室。因此，开发一种低成本、快速的 NA 监测分析方法将有助于应对这些挑战。阿尔伯塔大学最近与帝国石油资源有限公司合作开展的一项研究项目表明，基于微生物燃料电池 (MFC) 的生物传感器可以提供一种高效且经济高效的方法来监测水样中的 NA。该提案解决了开发这种用于现场应用的 MFC 生物传感器必须克服的挑战。该项目的范围包括了解各种NA之间的相互作用、各种环境参数的影响、在实际工艺水中检测NA的长期示范研究以及微型生物传感器的开发。预计这个为期两年的项目将最终开发出一种强大的 MFC 生物传感器，可用于油砂行业对 NA 进行现场量化或原位监测，从而确保油砂开采中的可持续环境管理手术。
