Acute Toxic Effects of Zinc Oxide Nanoparticle and Zinc Chloride on Daphnia magna (Straus)

Abstract

The acute toxicities of zinc oxide nanoparticle (ZnO NP), zinc chloride (ZnCl2) and their mixtures of different concentrations (0.75, 1.5, 3, 6 and 12ppm) on Daphnia magna (Straus, 1820) were investigated at 24, 48 and 72 hours by employing the static acute toxicity test. The data obtained were statistically evaluated by probit analysis method (SPSS 21.0v). The highest toxicity was found at 72 hours of the mixture (ZnO NP+ZnCl2) and the lowest toxicity was found at 24 hours of ZnCl2. When the overall acute toxicity results were considered, ZnO NP was determined to be more toxic than ZnCl2 and mixtures were determined to be more toxic than these two pollutants alone. When the results of time-dependent acute toxicity were evaluated, toxicity was found to increase with increasing time for all three experimental groups (ZnO NP, ZnCl2 and ZnO NP+ZnCl2).
