Description of key information

The toxic effect of the test item to Daphnia magna was assessed in a 48 h static test according to OECD guideline 202. A limit test with 177 mg/L test item was performed. 20 daphnids, divided into 4 replicates, each with 5 daphnids, and replicates were used for the test solution and the control. The mobility of the Daphnia was determined by visual observation after 24 and 48 hours.

Based on the test results the following dose descriptors were laid down:
