Endpoint:
short-term toxicity to fish
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Justification for type of information:
READ ACROSS CATEGORY APPROACH
A category group was formed with dipotassium peroxodisulphate (KPS), disodium peroxodisulphate (SPS) and diammonium peroxodisulphate (APS). Several physico-chemical, fate, ecotoxicological and toxicological endpoints were assessed using the category approach. Please refer to the read across justification in chapter 13 for further information.

Description of key information

The acute toxicity of the Persulfate Category to fish was tested in four studies. Three studies were available for diammonium persulfate and one for disodium persulfate. The studies were in accordance to FIFRA guideline 72-1 of the pesticide assessment guidelines, OECD guideline 203 and EU Method C.1. The most sensitive LC50 (96 h) value for freshwater was determined at 76.3 mg/L and for marine water at 107.6 mg/L.

Key value for chemical safety assessment

LC50 for freshwater fish:
76.3 mg/L
LC50 for marine water fish:
107.6 mg/L

Additional information

The acute toxicity of the Persulfate Category to fish was tested in four studies. Three studies were available for diammonium persulfate and one for disodium persulfate. For freshwater LC50 (96 h) values ranged from 76.3-163 mg/L. The acute toxicity study to fish with diammonium persulfate according to FIFRA guideline of the Pesticide Assessment revealed a LC50 (96 h) of 76.3 mg/L, the most sensitive value available. For the marine water LC50 (96 h) values ranged from 107.6-323 mg/L. The acute toxicity to marine fish with diammonium persulfate according to OECD guideline 203 revealed a LC50 (96 h) of 107.6 mg/L the most sensitive value available.
