Description of key information

The acute toxicity of the Persulfate Category to aquatic invertebrates was tested in eight studies. Six studies were available for diammonium persulfate and two for disodium persulfate. The studies were in accordance to FIFRA guideline 72-2 and 72-3 of the pesticide assessment guidelines, OECD guideline 202 and EU Method C.2. The most sensitive LC50 (48 h) value for freshwater was determined at 120 mg/L and for marine water at 11 mg/L (5 d).

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
120 mg/L
EC50/LC50 for marine water invertebrates:
11 mg/L

Additional information

The acute toxicity of the Persulfate Category to aquatic invertebrates was tested in eight studies. Six studies were available for diammonium persulfate and two for disodium persulfate. For freshwater EC50 values ranged from 120-356.7 mg/L. The acute toxicity study to Daphnia magna with diammonium persulfate according to FIFRA guideline 72-2 of the Pesticide Assessment revealed an EC50 (48 h) of 120 mg/L, the most sensitive value available. For the marine water EC50 values ranged from 11-391 mg/L. The acute toxicity to marine invertebrate Abra alba with diammonium persulfate according to PARCOM Ring test protocol revealed an EC50 (5 d) of 11 mg/L, the most sensitive value available.
