Description of key information

The 96-h LL50 obtained on the rainbow trout (Oncorhynchuss mykiss) for reaction mass of lanthanum phosphate and cerium phosphate and terbium phosphate is > 100 mg/L based on nominal loading rate, corresponding to > 264 μg/L based on mean measured concentration. Therefore, reaction mass of lanthanum phosphate and cerium phosphate and terbium phosphate is not harmful to fish up to its solubility limit into water. 

Key value for chemical safety assessment

Additional information

One GLP-compliant study is available on reaction mass of lanthanum phosphate and cerium phosphate and terbium phosphate. It is quoted as reliability 1 according to Klimisch criteria, flagged as a key study and it reveals that the substance is not harmful to fish up to its solubility limit into water.
