The sensitivity control showed a defecation rate of 39 % relative to the control, which is within the acceptable range for the reference substance (2.4 ppm of 3,5-Dichlorophenol), i.e. a fecal production rate of 25 - 45 5 of control after 5 days.

- Executive summary:
Diammonium persulfate was tested for toxic effects to the marine mollusc Abra alba in a test according to PARCOM Ring test criteria. In this test, the fecal pellet production rate of the mollusc Abra alba was recorded in comparison with an untreated control group and a peer group treated with 2.4 ppm of 3,5 -Dichlorophenol. Exposure time was 5 days. Under the conditions of this test, diammonium persulfate did not induce significant reduction of fecal pellet production by Abra alba exposed to a test concentration of 5 mg/L. No-observed-effect concentration (NOEC) was considered 5 mg/L. The EC50 (5 d) was 11 mg/l with a standard error of +/- 1 mg/L, corresponding to a 95 % confidence interval ranging from 9 to 13 mg/L.

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).

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.
