Description of key information

The Daphnia magna Reproduction Test (21 d) of the test item was conducted with different test item concentrations according to OECD 211.The test method was semi-static. The test solutions were renewed 3 times per week. Aim of the Daphnia Reproduction Test over 21 days was to assess effects on the reproduction capacity and other test item-related effects on parameters such as occurrence of aborted eggs and stillborn juveniles, time of production of first brood, adult mortality, intrinsic rate of natural increase, dry body weight and length of the parent animals. The study resulted a NOEC = 1.88 mg/L (measured).
