Portable Fluorometer for Field-Based Fluorescent Dissolved Organic Matter Measurements

溶解性有机物（DOM）是一种复杂的化合物混合物，对沃茨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物的产生有关。监测荧光DOM提供了快速和（接近）真实的时间测量水质和DOM组成。目前的方法使用脆弱，笨重和沉重的实验室设备3D ** 光谱仪，当从远程监测站点（如 ** 加拿大北极地区）工作时，成本可能过高。该项目旨在基于Wilson Analytical Services最近开发的明亮且稳定的LED技术开发一种新型便携式、灵敏且坚固的3D荧光光谱仪。我们的目标是（1）使用Guéguen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荧光计在北极条件下的耐用性，耐用性和 ** 灵敏度。这种尖端仪器将是 ** 第一个测量沃茨近真实的三维荧光的仪器。这种由加拿大开发的新技术可以迅速部署，用于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.
