Description of key information

With high probability acutely not harmful to aquatic invertebrates

Key value for chemical safety assessment

Additional information

The results as presented in a BASF AG study conducted in 1987 indicate that the test substance is probably not acutely harmful to daphnids. The EC50 based on mobility was determined to be > 500 mg/L.

Results are supported by an acute toxicty test according to EU Method C.2 (Acute Toxicty for Daphnia) from Hüls (1997). The EC50 (48 h) was measured to be 857 mg/L (nominal, confirmed by concentration control analytics).
