Our experiment focused on observation of the effect of combinations of ZnSO4.7H2O and CdCl2.2H2O on lethality to Artemia franciscana. The aim of the study was to observe the synergistic or antagonistic effects of these two metals. Depending on concentration, Cd may increase or decrease Zn toxicity. At higher concentrations of CdCl2.2H2O exceeding 100 mg/L one can observe obvious synergistic toxic effects of both substances. Our observations allowed us to conclude that the use of optimum, relatively low Cd concentrations (up to 50 mg/L CdCl2.2H2O) resulted in a significant decrease in lethality to Artemia franciscana caused by ZnSO4.7H2O at concentrations of 50, 100 and 250 mg/L.
