Changes in the Structure of Phytoplankton under the Influence of Urea

T. F. Shevchenko
Institute of Hydrobiology National Academy of Sciences of Ukraine Kiev, Ukraine

SINOPSIS

Heavy pollution of water by urea results in essential changes in the structure of phytoplankton. Cyanophyta proved to be most sensitive to the influence of high concentrations of ammonium. The quantitative indices of development of Cyanophyta decreased, whereas the numbers and biomass of Chlorophyta, primarily of Volvocales, increased with increasing the content of NH4+, ions in water.
