Description of key information

The acute toxicity of the test substance to invertebrates (Daphnia magna) is
EC0: 0.3 mg/L after 48 h
EC100: 1.0 mg/L after 48 h.
The study was conducted according to EU Method C.2 (Acute Toxicity for Daphnia)
(Bayer AG, 1993)
Estimation of the EC50-value with ToxRatPro Version 2.10
EC50: 0.5 mg/L after 48 h

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.5 mg/L

Additional information

The experimental value from Bayer 1993 (48h-EC50= 0.5 mg/L) is supported by an Ecosar estimation yielding an 48h-EC-50 of 2.2 mg/L.
