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（NAs）是炼油厂废水和油砂工艺影响水（OSPW）的主要急性毒性和内分泌干扰源。NAs渗透到周围地表和地下水中，对水生生态系统和环境造成的不利影响日益受到关注。因此，对这些废水中的NAs进行常规监测对于油砂工业至关重要。 用于分析水样中NAs的现有分析方法耗时且昂贵，并且需要将样品送到分析实验室。因此，开发一种低成本和快速的分析方法来监测NA将有助于应对这些挑战。最近在阿尔伯塔大学与帝国石油资源有限公司合作进行的一项研究计划表明，基于微生物燃料电池（MFC）的生物传感器可以提供一种有效且具有成本效益的方法来监测水样中的NAs。该提议解决了开发用于现场应用的MFC生物传感器所必须克服的挑战。该项目的范围包括了解各种NAs之间的相互作用，各种环境参数的影响，真实的工艺用水中NAs检测的长期示范研究，以及小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的现场定量或原位监测，从而确保油砂开采作业的可持续环境管理。
