活体荧光法已被公认为是一种快速、简单和有用的浮游植物生物体定量分析工具。在本文中，我们提出了一个案例研究，其中荧光方法用于选择性检测潜在的有毒蓝藻在饮用水处理厂的原水。蓝藻在饮用水水库和原水的发生进行了监测藻蓝蛋白荧光测量和浮游植物定量（细胞计数，叶绿素a）的标准方法。一个特别注意的是最关键的部分的季节-春季招聘蓝藻从沉积物到水柱和秋季水华崩溃。所有方法在季节内显示出相似的模式。藻蓝蛋白荧光被发现是水中蓝藻的一种简单而敏感的指示剂，可以作为一种工具，可以提供有关水中潜在有毒蓝藻代谢物存在的早期预警。
in vivo fluorescence methods have been accepted as a quick, simple, and useful tool for quantification of phytoplankton organisms. In this paper, we present a case study in which fluorescence methods were employed for the selective detection of potentially toxic cyanobacteria in raw water at the drinking water treatment plant. The occurrence of cyanobacteria in the drinking water reservoir and in raw water was monitored by phycocyanin fluorescence measurements and by standard methods for phytoplankton quantification (cell counts, chlorophyll a). A special attention was paid to the most critical parts of the season - spring recruitment of cyanobacteria from sediment to water column and autumn bloom collapse. All methods showed similar patterns within the season. Phycocyanin fluorescence was found to be a simple and sensitive indicator of cyanobacteria in water and can serve as a tool that can provide an early warning about the presence of potentially toxic cyanobacterial metabolites in water.
