Portable Fluorometer for Field-Based Fluorescent Dissolved Organic Matter Measurements

溶解有机物(DOM)是一种复杂的化合物混合物，对水体中**污染物的毒性有很大影响。荧光DOM与**水处理厂的气味和致癌产品的生产有关。监测荧光DOM提供对水质和DOM组成的快速和(接近)实时测量。目前的方法使用脆弱、笨重的实验室设备3D**光谱仪，当在**加拿大北极等远程监测点工作时，这些光谱仪的成本可能会高得令人望而却步。该项目旨在基于威尔逊分析服务公司最近开发的明亮稳定的LED技术开发一种新型便携式、灵敏和坚固耐用的3D荧光**光谱仪。**我们的目标是(1)使用Guéguen团队在北冰洋和加拿大河流收集的10年以上的数据集**确定DOM的关键荧光特性，以及(2)评估所开发的便携式3D荧光仪在北极条件下的坚固性、耐用性和**灵敏度。这一尖端仪器将是同类仪器中第一个测量近乎实时的水域3D荧光的仪器。这项由加拿大开发的新技术可以快速部署，以监测加拿大和其他地方的自然水状况以及人为泄漏和**泄漏，包括石油和石油泄漏以及废水泄漏控制。

Dissolved organic matter (DOM) is a complex mixture of compounds that influences strongly the toxicity of**contaminants in waters. Fluorescent DOM has been related to odor and production of carcinogenic products in**water treatment plants. Monitoring fluorescent DOM offers rapid and (near) real time measurement of water**quality and DOM composition. Current methods use fragile, bulky and heavy laboratory equipment 3D**spectrometers which can be cost prohibitive when working from remote monitoring sites such as in the**Canadian Arctic. The project aims to develop a new portable, sensitive and rugged 3D fluorescence**spectrometer based on the recently developed bright and stable LED technology by Wilson Analytical Services.**Our goals are to (1) determine the key fluorescent characteristics of DOM using the 10+ years dataset collected**by Guéguen's group in the Arctic Ocean and Canadian rivers and (2) to assess ruggedness, durability and**sensitivity of the developed portable 3D fluorometer in Arctic conditions. This cutting edge instrument will be**the first of its kind to measure near real time 3D fluorescence of waters. This new Canadian-developed**technology can be rapidly deployed to monitor natural water conditions as well as man-made spills and**leakages including petroleum and oil spills and wastewater leakage controls in Canada and elsewhere.
