Description of key information

The determined EC50 of quinine sulphate for green algae Dunaliella salina is 14.5 mg/L. According to this, the EC50 of quinine is 11.13 mg/L. We conclude that cinchonidine which differs in a methoxy group has a similar EC50 value.

Key value for chemical safety assessment

EC50 for marine water algae:
11.13 mg/L

Additional information

This experimental study was published by Moreno-Garrido, 2001. In this publication, the toxicity of the read across substance quinine sulphate for green algae Dunaliella salina was determined for 72 h in saltwater. The determined EC50 of quinine sulphate is 14.5 mg/L. According to this, the EC50 of quinine is 11.13 mg/L. We conclude that cinchonidine which differs in a methoxy group has a similar EC50 value.
