“…Russia possesses the world's second renewable water reserves after Brazil [13]. A significant number of scientific publications as well as reports in the mass media show that the problem of eutrophication is widespread in Russia [14][15][16][17][18][19][20].…”

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.

“…The problem of preventing cyanobacterial blooms is extremely important and very relevant in Russia and abroad [1,8,16,30]. Currently, along with the existing chemical and bacteriological methods, more environmentally friendly methods are being developed to control the cyanobacterial blooms in waterbodies, e.g., the use of weak ultrasound [7,11,15,25,32].…”

Spectroscopic Techniques for Estimation of Physiological State of Blue-Green Algae after Weak External Action

2018

Nowadays cyanobacterial blooms in open reservoirs and estuaries became one of the most important ecological problem. The optimal way to solve this problem is to develop innovative methods for controlling the number of bloom-forming cyanobacteria based on weak external actions, which have no serious consequences for the entire ecological system. A novel efficient technique for in vivo estimation of cyanobacterial viability for online ecological monitoring of the results of weak external actions was elaborated by using a combination of different spectroscopic methods. It has been shown that the results obtained by means of conventional spectrophotometry and fluorimetry for cyanobacterial culture as a whole and the data obtained by fluorescent microscopic spectroscopy applied to a single cell are strictly related.
