Description of key information

One long term toxicity test with daphnia has been performed in accordance with OECD 211. The NOEC for reproduction is 270 µg/L. The EC10 and EC50 for parental mortality are resp. 200  and 240 µg/L. The effects are expressed as nominal values because the tests were performed with river water as they are intended to be used in an evaluation of the environmental risks based on the Bulk approach.

Additional information

As a worst-case the EC10 for parental mortality of 200 µg/L is used for risk assessment purposes and not the NOEC of 270 µg/L for reproduction. The EC50 for parental mortality is 240 µg/L.
