Description of key information

EC50 48h Daphnia magna = 8.6 mg/L

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
8.6 mg/L

Additional information

Three studies on Daphnia magna have been reported, performed following OECD 202 guideline. Hisgen Hr. (2003) study has been performed as a limit test and no toxicity has been observed until a nominal concentration of 100 mg/l, but the active ingredient being only 23%, the result can not be taken into consideration for classification.

The other two studies are full studies and the results are consistent. The Tereza Špásová (2012) study and the value of EC50 8.6 mg/L has been taken as a key because it has been performed in GLP.
