Naphthenic acids (NAs) represent the primary source of acute toxicity in oil sands process affected water. Due to the seepage potential of NAs from oil sands tailings ponds into the surrounding surface water and groundwater, environmental monitoring of NAs in water samples from tailing ponds, surrounding groundwater and surface water, and groundwater wells became a routine part of oil sands mining operations. Commonly used analytical techniques for NA concentrations measurement include Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry, and high-performance liquid chromatography-mass spectroscopy. However, these methods are time-consuming and resource-intensive, and samples need to be sent to an analytical laboratory which can cost up to $1,000 per sample. Hence, developing a fast, low-cost analytical method for on-site quantification of NAs will help address these challenges. Consequently, this project aims to develop a simple bio-electrochemical sensor for rapid and on-site quantification of oil sand-related NAs in water samples.

环甲酸（NAS）代表油砂过程中急性毒性的主要来源。由于NAS从油砂尾矿池塘中渗透到周围的地表水和地下水中，因此对NAS的环境监测，从尾池，周围的地下水和地表水中对NAS进行环境监测，而地下水井成为了油砂挖掘业务的常规部分。用于NA浓度测量的常用分析技术包括傅立叶变换红外光谱，气相色谱 - 质量光谱法和高性能液态色谱 - 质谱法。但是，这些方法是耗时的和资源密集的，需要将样品发送到一个分析实验室，该实验室每样本的费用最高为1,000美元。因此，开发一种快速，低成本的分析方法，用于现场定量NAS，将有助于应对这些挑战。因此，该项目旨在开发一个简单的生物电化学传感器，以快速和现场定量水样中的油砂相关NAS。
