- Endpoint:
- toxicity to microorganisms, other
- Remarks:
- Acute bacteria Cell Multiplication Inhibition Test
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1988-07-19 to 1988-08-18
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- 1. There was no information on the pH during the test, the test medium used differed slightly from the medium described in DIN 38412 Teil 8 (1991). 2. The growth factor could not be deduced from the report (DIN 38 412 Teil 8: 100 after 18 h). The positive control was reported to fall within the acceptable range (EC10 20611 mg/L; literature EC10 6600 mg/L). The study reliability was lowered, because it cannot be excluded that the growth factor was sub-optimal (DIN 38412 part 8).

- Executive summary:
Diammonium persulfate was investigated for its ability to inhibit the cell multiplication of the bacteria species Pseudomonas putida according to study guidelines NPR 6508 and NEN 6509. Cultures of the bacteria were exposed to concentrations ranging from 6.00E-06 mg to 100 mg/L. An EC10 was determined at 36 mg/L.

Description of key information
The toxicity of microorganisms to diammonium persulfate was tested in a study according to guidelines NEN 6509 and NPR 6508. The study revealed an EC10 (18 h) of 36 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 36 mg/L
Additional information
In the key study the toxicity of diammonium persulfate to the gram negative bacterium Pseudomonas putida was determined in a growth inhibition test according to guidelines NEN 6509 and NPR 6508. Bacteria were exposed in a static test to concentrations of diammonium persulfate up to 100 mg/L. The study revealed an EC10 (18 h) of 36 mg/L.
