Description of key information

The 72h-ErL50 obtained on Scenedesmus subspicatus for Reaction Mass of Lanthanum Phosphate and Cerium Phosphate and Terbium Phosphate  is > 100 mg/L based on nominal loading rate, corresponding to > 42 μg/L based on measured concentration. The 72h-NOELR is ≥ 100 mg/L based on nominal loading rate. Therefore, Reaction Mass of Lanthanum Phosphate and Cerium Phosphate and Terbium Phosphate is not harmful to algae up to its solubility limit into water.

Key value for chemical safety assessment

Additional information
