RÉSUMÉ

The influence of N-dimethylnitrosamine (DMNA) on the intensity of development of river phytoplankton was studied. It has been found that the number of algal species decreased with increasing the concentration of the toxicant in water. DMNA concentrations of 120 mg/L and more had an adverse effect on the complex of dominant species. All the studied concentrations of DMNA stimulated the development of Euglenophyta. The response of particular algal species to contamination of the aquatic environment by N-nitrosamines was revealed.
