Dealing with toxic algae blooms in Mattatall Lake (Nova Scotia) to improve the water quality and to suggest a sustainable treatment for eutrophic water cyanobacteria

最近，大量蓝藻(蓝藻或有害藻华-HAB)入侵 位于新斯科舍省(NS)的Mattatall湖(ML)，并对这一湖泊环境以及 流域周围栖息地：野生动物和鸟类已离开湖泊，人和动物不能进入 这个湖对双方都是有毒的。这是该地区的一个新问题，很容易蔓延到新大陆的其他湖泊。 斯科舍。ML的捕鱼和娱乐活动急剧减少，对 对ML社区内的许多企业产生影响。有害的藻类水华不仅破坏了 景观美景，它们主要影响饮用水的来源，对水质(气味， 口味等)。由于它们可能产生大量的毒素，因此必须对哈勃进行认真的研究，以更好地 了解它们的发展及其对环湖社区公共卫生的任何影响 分水岭。大西洋水处理技术(AWTT)，布雷顿角的水修复公司 (NS)，因此希望参与ML被HAB污染的水的处理过程。 然而，由于缺乏了解赤潮问题的数据和工具，特别是对于奇怪的蓝藻 水华一直持续到冬天，AWTT公司来到生物流体和生物系统模型实验室 阮光博士的(BBML)请求协助。AWTT认为ML水处理的这个例子是 有机会开发新服务并继续增长业务。因此，这个项目是一项共同努力。 阮光博士和AWTT之间的关系。具体目标包括：1)了解蓝绿 不同微营养水平下藻类水华发生及生化物理耦合效应 因素；解释环境参数和人为因素的作用模式；2)建议 与湖泊水质有关的监测框架和可能的可持续解决方案 问题。

Recently, massive blooms of blue-green algae (cyanobacteria or harmful algae bloom - HAB) have invaded Mattatall Lake (ML) in Nova Scotia (NS) and had an adverse effect on this lake environment, as well as on living habitats around its watershed: the wildlife and birds have left the lake, people and animals cannot go into the lake as it is toxic to both. This is a problem new to this area and could easily spread to other lakes in Nova Scotia. The fishing and recreational activities in ML have drastically diminished and have had an adverse effect on many businesses within the ML community. The harmful algal blooms are not only destroying the landscape beauty, they mainly affect sources of drinking water, negatively influencing their quality (smell, taste, etc.). Because of quantity of toxins they may produce, HABs have to be seriously studied to better understand their development and any impact in public health of the community living around the lake watershed. The Atlantic Water Treatment Technologies (AWTT), a water remediation company in Cape Breton (NS), therefore expects to get involved in the treatment process for the water contaminated by HAB in ML. However, due to the lack of data and tools to understand the HAB problem, especially for odd cyanobacteria blooms persisting until winter, the company AWTT came to the Biofluids and Biosystems Modeling Lab (BBML) of Dr. Nguyen-Quang for assistance. AWTT considers this example of ML water treatment as an opportunity to develop new services and continue to grow its business. Hence, this project is a joint effort between Dr. Nguyen-Quang and AWTT. The specific objectives include: 1) Understanding the blue-green algae bloom occurrence under different micro-nutrient levels and coupling effects of biochemical physical factors; to explain the pattern in function of environmental parameters and anthropogenic factors; 2) to suggest a monitoring framework related to water quality of the lake and a possible sustainable solution for this harmful issue.
