Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

No studies on toxicity to microorganisms with disodium persulfate were available. A read across approach was applied to studies with diammonium persulfate, as the substance shows similar ecotoxicological properties. The toxicity of microorganisms to diammonium persulfate was tested in a study according to guidelines NEN 6509 and NPR 6508. The study revealed an EC10 (18 h) of 36 mg/L.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
36 mg/L

Additional information

No study on toxicity to microorganisms with disodium persulfate was available. Instead a read across approach was applied to assess the toxicity to microorganisms using data available for diammonium persulfate, a substance considered to exhibit comparable ecotoxicological properties. In the key study the toxicity of diammonium persulfate to the gram negative bacterium Pseudomonas putida was determined in a growth inhibition test according to guidelines NEN 6509 and NPR 6508. Bacteria were exposed in a static test to concentrations of diammonium persulfate up to 100 mg/L. The study revealed an EC10 (18 h) of 36 mg/L.
