Additional information

The acute toxicity of the test substance to aquatic invertebrates was determined in a GLP-compliant test according to OECD 202 (RCC, 2005).

In this study, Dapnia magna (4 replicates of 5 daphnids each) were exposed to nominal concentrations of 0, 1.0, 3.2, 10, 32 and 100 mg/L of the test substance for 48 hours (static). During the test, recovery of test substance ranged from 111 to 120% of the nominal concentrations. After 48 hours, immobilization was observed at 32 mg/L (15%) and 100 mg/L (80%). Using probit analysis, the 48-h EC50 was determined to be 60.2 mg/L (nominal concentration).
