Description of key information
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
