项目摘要

Cyanobacteria, commonly known as blue-green algae, are naturally occurring microscopic organisms that may release cyanotoxins into freshwater systems. These toxins pose a serious public health risk as exposure through skin contact, ingestion of lake water, or contaminated drinking water or food may cause symptoms impacting both animals (livestock and pets) and humans. These risks range from minor irritation to more serious illness and, in worst case scenarios, can be fatal.Cyanobacteria occur worldwide, in calm, nutrient-rich waters, allowing algal blooms. These blooms may occur at any time of year but are more common during summer and early fall, creating bad odors, water discoloration, accumulate as a scum on the surface of the water, and releasing toxins that may be harmful to humans and aquatic biota. The expectations are that blooms will increase in frequency and duration in urban lakes due to warming temperatures associated with climate change.With the increasing incidence of cyanotoxins, interest is focusing on understanding the pathways of factors which contribute to formation of cyanotoxins and ultimately, opportunities to manage urban lakes and hence insights to decrease the potential for algal blooms to occur (e.g. manage/decrease nutrient loads, consider physical and chemical activities to reduce the blooms, and develop scientific knowledge using modern techniques such as microbial source tracking, and create tools to assess their magnitude and potential). Currently, models to specifically predict harmful algal composition and toxicity are lacking and improved knowledge of the effectiveness of possible control measures are needed.This research will focus on a case study application to Fairy Lake, a 26 ha Provincially Significant Wetland in the Town of Halton, Ontario where the algal growths are substantial and a considerable history of data are available. Fairy Lake is ideal for this research, given the interested parties, the proximity allowing relatively easy access, and the expertise within the proposed research team.
蓝藻,俗称蓝藻,是一种自然存在的微生物,可能会向淡水系统释放氰毒素。这些毒素构成严重的公共卫生风险,因为通过皮肤接触、摄入湖水或受污染的饮用水或食物可能会导致影响动物(牲畜和宠物)和人类的症状。这些风险从轻微的刺激到更严重的疾病,在最糟糕的情况下,可能是致命的。蓝藻在世界各地都存在,出现在平静、营养丰富的水域,使藻类大量繁殖。这些水华可能发生在一年中的任何时候,但更常见的是在夏天和初秋,造成恶臭,水变色,作为浮渣积累在水面上,并释放出可能对人类和水生生物群有害的毒素。由于气候变化引起的温度变暖,城市湖泊水华的发生频率和持续时间将增加。随着氰化毒素发生率的增加,人们的兴趣集中在了解促成氰化毒素形成的因素的途径上,并最终了解管理城市湖泊的机会,从而获得减少藻类水华发生的可能性的见解(例如,管理/减少营养负荷,考虑物理和化学活动以减少水华,利用现代技术,如微生物来源追踪,发展科学知识,并创造工具来评估其规模和潜力)。目前,缺乏专门预测有害藻类成分和毒性的模型,需要更好地了解可能的控制措施的有效性。这项研究将集中在应用于仙女湖的案例研究,仙女湖是安大略省哈尔顿镇26公顷的重要湿地,那里藻类大量生长,有相当多的历史数据可用。仙女湖是这项研究的理想选择,因为有感兴趣的各方,距离较近,可以相对容易地进入,以及拟议的研究团队内的专业知识。
