Abstract
The article presents the results of experimental studies to assess the impact of heavy metals on the functioning of phyto- and zooplankton (Scenedesmus quadricaud, Daphnia magna). Determination of inactive and threshold concentration of strontium, toxicity parameters and the degree of acute toxicity has been carried out. As a result of the studies the data on the effect of strontium on hydrobionts of different trophic links were obtained. For zooplankton in terms of survival rate the maximum allowable concentration of strontium was 4 mg/l, in terms of fecundity - 2 mg/l in terms of fecundity. According to the indicator of single-celled algae Sc. quadricauda viability (cell number) in the chronic experiment the maximum allowable concentration of strontium is 2 mg/l.
