Sampling and analysis
- Analytical monitoring:
- no
- Details on sampling:
- The test substance was suspended in artificial sewage at nominal loadings of 20, 500 and 1,000 mg/L using a 30- minute sonication to assist dispersion. The test flasks were inoculated with sewage sludge bacteria and aerated for 30 minutes. Following aeration the contents of the flasks were poured into darkened 300 mL BOD bottles fitted with oxygen sensing electrodes.
Test solutions
- Vehicle:
- no
- Details on test solutions:
- The test substance was suspended in artificial sewage at nominal loadings of 20, 500 and 1,000 mg/L using a 30 minute sonication to assist dispersion.
Test organisms
- Test organisms (species):
- activated sludge of a predominantly industrial sewage, de-adapted
Study design
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
Test conditions
- Reference substance (positive control):
- yes
- Remarks:
- 3,5-dichlorophenol
Results and discussion
Effect concentrations
- Duration:
- 30 min
- Dose descriptor:
- other: inhibition of the rate of oxygen consumption
- Effect conc.:
- other: None of the tests indicated any significant inhibition of bacterial respiration compared with the controls
- Details on results:
- None of the tests indicated any significant inhibition of bacterial respiration compared with the controls.
- Results with reference substance (positive control):
- In contrast to the BDP, the reference substance with 3,5-dichlorophenol inhibited bacterial respiration by 7% at a test concentration of 3.2 mg/L, and 84% at 32 mg/L.
Any other information on results incl. tables
It was concluded that the BDP is not toxic to sewage bacteria up to the limits of its water solubility.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- It was concluded that the BDP is not toxic to sewage bacteria up to the limits of its water solubility.
