Administrative data
Link to relevant study record(s)
- Endpoint:
- activated sludge nitrification inhibition testing
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Data is from peer reviewed journal
- Justification for type of information:
- Data is from peer reviewed journal
- Qualifier:
- according to guideline
- Guideline:
- other: as mentioned below
- Principles of method if other than guideline:
- luminiscence reduction test was performed for test material on Photobacterium phosphoreum
- GLP compliance:
- not specified
- Test organisms (species):
- other: P. phosphoreum
- Test type:
- static
- Water media type:
- freshwater
- Total exposure duration:
- 30 min
- Test temperature:
- 15 deg C
- Duration:
- 30 min
- Dose descriptor:
- EC50
- Effect conc.:
- 0.22 mg/L
- Nominal / measured:
- not specified
- Conc. based on:
- test mat.
- Basis for effect:
- other: luminiscent
- Conclusions:
- The effect concentration EC50 of test material on P. phosphoreum was evaluated to be 0.22 mg/l
- Executive summary:
Microtox bioassay was performed for the test material on P. phosphoreumbased on the light emission of these bacteria, as a measurement of their metabolic activity. 50% reduction of the light emitted by the bacteria (EC50) is calculated from a concentration response curve by regression analysis. The osmotic pressure of the samples was adjusted by NaCl addition (2%). Toxicity data were based on a 30-min exposure of bacteria to the surfactant solution at 15 deg C. The effect concentration EC50 of test material on P. phosphoreum was evaluated to be 0.22 mg/l
