Description of key information

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
18.8 mg/L

Additional information

As no data is available on the reaction mass of m-Cresol and p-Cresol, the assessment is based on data available on individual constituents. The most severe toxicity value was obtained with a freshwater crustacean species (Daphnia magna) exposed for 48 hours to m-Cresol: 48h-LC50 = 18.8 mg/L. As a worst-case, this value is assigned to the reaction mass for the assessment.
