The Acute Toxicity of Zinc chloride on Daphnia magna Straus

Abstract

In this study the acute toxicity of zinc chloride (ZnCl₂) to Daphnia magna Straus was investigated in a static bioassay. After 24, 48, 72 and 96 h the mobility of daphnids were examined and immobile ones were counted. The 24, 48, 72 and 96 h EC₅₀ of zinc chloride to D. magna were found as 11.63, 6.03, 1.17 and 0.67 mg/L, respectively.
