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，大规模的蓝藻水华（蓝藻或有害藻类水华- HAB）已经入侵 在新斯科舍省（NS）的Mattatall湖（ML），并对该湖泊环境以及 流域周围的生物栖息地：野生动物和鸟类已经离开湖泊，人和动物无法进入 湖水对两者都有毒。这是一个新的问题，这一地区，很容易蔓延到其他湖泊在新星 斯科舍。ML的捕鱼和娱乐活动急剧减少， 对ML社区中的许多企业产生影响。有害的藻类大量繁殖不仅破坏了 景观美，它们主要影响饮用水源，对水质产生负面影响（气味， 味道等）。由于它们可能产生大量毒素，因此必须对赤潮进行认真研究， 了解它们的发展以及对居住在湖周围社区的公共卫生的任何影响 流域大西洋水处理技术公司（AWTT），一家位于布雷东角的水治理公司 (NS)因此，希望能参与到ML受赤潮污染水体的治理过程中。 然而，由于缺乏数据和工具来了解HAB问题，特别是对于奇数蓝藻 开花持续到冬天，AWTT公司来到生物流体和生物系统建模实验室 （BBML）Nguyen-Quang博士的协助。AWTT认为ML水处理的这个例子是一个 有机会开发新服务并继续发展业务。因此，这个项目是一个共同的努力 阮光医生和AWTT之间的联系具体目标包括：1）理解蓝绿 不同微量营养盐水平下水华的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功能模式; 2）建议 一个与湖泊水质有关的监测框架，以及一个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.
