Description of key information

A 96-h Acute Toxicity study in carp was performed with SrHPO4 according to OECD 203 and in compliance with GLP principles. The test substance solution was prepared as a water soluble fraction of a loading rate of 100 mg/L. Preparation of test solution started with a loading rate of 100 mg/L applying a 2-day period of magnetic stirring followed by a filtration through a 0.45 µm membrane filter. The actual measured concentration of the WSF was 12 mg Sr/L at the start of the test and remained stable during exposure. No effects were observed and thus the 96h-LC50 was considered to exceed the maximum solubility of the test substance in medium.

Key value for chemical safety assessment

Additional information

Key value for CSA: 96h-LC50 is > the maximum solubility of the test substance in medium.
