ABSTRACT

The response of plankton algae occurring in water bodies of various types to the influence of fulvic acids isolated from the water of the Kanev Reservoir (Ukraine) was investigated. The concentration of the studied substances introduced into the samples of the natural water accounted for 30.0 and 80.0 mg/L. The response of phytoplankton to the influence of fulvic acids was judged from changes in its numbers and biomass. Representatives of Cyanophyta, Chlorophyta, Euglenophyta, Bacillariophyta, and Dinophyta differed in their response to the influence of the studied organic substances.
