营养物进入水体引起的富营养化可能导致藻华。俄罗斯拥有世界第二高的可再生淡水资源，多年来一直面临富营养化问题。然而，据我们所知，在此之前还没有对俄罗斯的藻华情况进行过全面的分析。我们分析了2016年至2018年关于藻爆发的大众媒体和科学报道，这使我们能够确定俄罗斯藻华的地理分布，以及富营养化的主要影响。结果，我们发现藻华发生在所有主要气候带和所有联邦区。蓝藻是最常报道的光合生物，包括位于俄罗斯大陆部分和波罗的海的淡水水库的藻华。鞭毛藻为主的藻华在太平洋东北部沿海地区更为典型。最多的报告来自俄罗斯欧洲部分的南部。然而，我们没有发现可能影响富营养化的因素（如人口、耕地面积、肥料、牲畜、气温等）的国家统计数据与该地区藻类暴发数量之间存在显著相关性。大众媒体分析显示，藻华在俄罗斯引起了相当大的公众关注，这需要科学界积极参与解决问题。
Eutrophication caused by the entry of nutrients into a water body may lead to algal bloom. Russia possesses the world's second highest supply of renewable freshwater resources and has faced the problem of eutrophication for many years. Nevertheless, as far as we know, no general analysis of Russia's algal bloom situation has been before carried out. We have analyzed mass media and scientific reports about algal outbreaks from 2016 to 2018, which allowed us to determine the geographical distribution of algal blooms in Russia, as well as the major effects of eutrophication. As a result, we showed that algal blooms happened in all major climate zones and all federal districts. Cyanobacteria are the most frequently reported photosynthetic organisms comprising algal blooms in freshwater reservoirs located in the continental part of Russia and in the Baltic Sea. Dinoflagellate dominated blooms are more characteristic for the coastal parts of the northeastern Pacific Ocean. The largest number of reports comes from the south of the European part of Russia. However, we did not find significant correlations between state statistics data on factors possibly affecting eutrophication (e.g., population, arable land area, fertilizers, livestock, air temperature, etc.) and the number of algal outbreaks in the regions. Mass media analysis showed that algal blooms attract considerable public attention in Russia, which requires the scientific community to actively participate in solving the problem.
