Description of key information

EC50 (96 h) 0.8 mg/L Nitocra spinipes

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.8 mg/L

Additional information

A 96 h LC50 value of 0.8 mg/L has been determined for the effect of the test substance on the mortality of the brackish water invertebrate Nitocra spinipes. This represents the only reliable measured value available for this endpoint and has been chosen as key.

No data are currently available with Reaction mass of 2-butylheptan-1-ol and 2-ethylnonan-1-ol and 2-methyldecan-1-ol and 2-propyloctan-1-olfor this endpoint. However data aer available with the closely related substance undecanol (CAS 112-42-5). It is possible to validly read-across data between the two substances, as outlined in the overall aquatic toxicity endpoint summary.
