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，它强烈影响水中污染物的毒性。荧光DOM与**水处理厂的气味和致癌物质的产生有关。监测荧光DOM提供快速和（近）实时测量水质和DOM组成。目前的方法使用易碎、笨重和沉重的实验室设备3D光谱仪，当在加拿大北极等远程监测点工作时，这种仪器可能成本过高。该项目旨在开发一种新的便携式，灵敏和坚固的3D荧光光谱仪，该光谱仪基于威尔逊分析服务公司最近开发的明亮和稳定的LED技术。我们的目标是：(1)利用gusamuen小组在北冰洋和加拿大河流中收集的10多年数据集确定DOM的关键荧光特性；(2)评估开发的便携式3D荧光仪在北极条件下的坚固性、耐用性和灵敏度。这种尖端的仪器将是**同类中第一个测量近实时三维荧光的水。这项由加拿大开发的新技术可以快速用于监测自然水情以及人为泄漏和泄漏，包括加拿大和其他地方的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.
