Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 133.3 mg/L
Additional information
Based on the Key study results the estimated NOEC of Chlorella vulgaris for aluminium potassium bis sulphate is 133.3 mg/L.
In a supporting study by DeForest et al., experimental data on the toxicity of aluminium to a green alga (P. subcapitata) is summarized. Within these data, the EC10 (72 hours, Pseudokirchneriella subcapitata) for Aluminum varies over a wide range (146 - 3154 µg Al/lcorresponding to ca. 1.4 - 30.5 mg/l aluminum potassium bis(sulphate)) depending on the water characteristics (pH, DOC, hardness). The actual aluminum compound used as test material was not specified.
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.
