Studying of influence of ions of manganese (II) on the level of fluorescence of the chlorophyll of scenedesmus quadricauda

Kamenets A.   (Saratov State Technical University of Y. A. Gagarin)

It is shown that presence at water systems of salts of manganese at concentration from 0,001 mg/l and exerts the significant negative effect on the level of vital activity S. quadricauda determined by decrease in intensity of fluorescence of a chlorophyll of seaweed in comparison with control above. At the same time low concentration of ions of manganese (0,001 and 0,005 mg/l) don't lead to acute toxicity of the water environment.

Keywords:influence, Scenedesmus quadricauda, concentration, manganese, toxicity, fluorescence.
