Description of key information

The performance of the toxicity to birds test was scientifically not justified.

Key value for chemical safety assessment

Additional information

In accordance to Column 2 REACH Annex X 9.61, reproductive toxicity test to birds, can be waived if mammalian dataset is available (see toxicological studies section 7). In addition direct and indirect exposure to birds is unlikely as the substance hydrolyses upon contact with water into cation and persulfate anion. Decomposition rates increase with decreasing pH value and increasing temperature. The persulfate anion, independent of the cation, undergoes further decomposition in normal water or acid conditions, readily oxidising water to oxygen, producing sulphate and hydrogen ions. All persulfate decomposition products are ubiquitous to the environment. Hydrolysis is metal catalysed, and rapid reaction with organic matter is also possible. Thus persulfates are not expected to be distributed into soil and consequently, also not to cause toxicity to birds. Therefore, testing toxicity with birds is scientifically not justified.
