On the example of natural (river Kitenka) and artificial (leachate a municipal landfill "Sofrony", Perm) water objects under the influence of anthropogenic impact, a significant transformation of phytoplankton was shown. The development of Euglenophyta, Chlorophyta and Cyanoprokaryotf, characteristic of polluted eutrophic waters, was revealed. The reorganization of the structure of algocenoses associated with an increase in the proportion of Cyanoprokaryota (75% of the abundance and 25% of the biomass), Euglenophta (23% of the abundance and 45% of the biomass) or Chlorophyta (20% of the abundance and 30% of the biomass) algae was analyzed. The phytoplankton of the studied objects are characterized by significant fluctuations in abundance and biomass, regardless of the periods of observation. With excessive anthropogenic impact, inhibition of algocenoses, or their complete degradation, was found.
