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.

环烷酸(Nas)是油砂工艺水中急性毒性的主要来源。由于油砂尾矿库中的NAS可能渗入周围的地表水和地下水中，对尾矿库水样、周围地下水和地表水以及地下水井中NAS的环境监测成为油砂开采作业的常规部分。常用的分析技术有傅里叶变换红外光谱仪、气相色谱-质谱仪和高效液-质联用法。然而，这些方法既耗时又耗费资源，而且需要将样品送到分析实验室，每个样品的成本可能高达1000美元。因此，开发一种用于现场量化NAS的快速、低成本的分析方法将有助于应对这些挑战。因此，本项目旨在开发一种简单的生物电化学传感器，用于水样中与油砂相关的NAS的快速和现场定量。
