Description of key information

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

EU method C.2.

In the preliminary test, nominal concentration were: 1, 5, 10, 50 and 100 mg/l. Stability of test concentrations was assessed in terms of TOC. At 100 mg/l, TOC variation between 0 and 48 h was of 12.3 %. Higher variation was seen at 1 mg/l, likely due to the uncertainty of measurement. Final results were expressed as nominal concentrations.

As no toxic effects were seen in all groups, the study was terminated upon the preliminary test.
