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.

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.
