Description of key information

The acute toxicity of the Persulfate Category to aquatic algae was tested in four studies. One study was available for disodium persulfate and three for diammonium persulfate. The studies were in accordance to OECD guideline 201 and EU Method C.3. The most sensitive EC50 (72 h) value for marine water was 320 mg/L with a NOEC of 32 mg/L.

Key value for chemical safety assessment

EC50 for marine water algae:
320 mg/L
EC10 or NOEC for marine water algae:
32 mg/L

Additional information

The acute toxicity of the Persulfate Category to aquatic algae was tested in three studies. One study was available for disodium persulfate and three for diammonium persulfate. The marine algal growth inhibition test with diammonium persulfate revealed an EC50 (72 h) of 320 mg/L, the most sensitive value available.
