HYDROCHEMICAL RESEARCH AND PHYTOPLANKTON OF SALT LAKES OF PAVLODAR REGION

Abstract

This article provides data on phytoplankton and hydrochemical indicators of water of salt lakes of Pavlodar region of Lake Seiten and Sharbakty, for the spring and autumn periods of 2021. The purpose of this work is to determine the taxonomic composition of phytoplankton. The trophic status of phytoplankton biomass was assessed. In the plankton of Lake Seiten, 4 taxa from 3 departments of microalgae were identified. The phytoplankton of Lake Sharbakty is characterized by 7 species and forms of algae from 4 groups. In spring and autumn, the biomass of the phytoplankton of Seiten and Sharbakty lakes was rated "very low" on the trophy scale of S.P. Kitaev. Changes in ion-salt composition, mineralization and oxidability of water were revealed. Biogenic compounds during the spring and autumn periods vary within a range sufficient in concentration for the development of phytoplankton. This research has is funded by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan (Grant No. AP09058158).
