Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: screening tests
- Type of information:
- other: estimation by calculation
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Guideline:
- other: REACH guidance on QSAR R.6, May 2008
- Principles of method if other than guideline:
- BIOWIN program v4.10: scientifically accepted calculation method for organic chemicals
- GLP compliance:
- no
- Remarks:
- not applicable
- Inoculum or test system:
- other: not applicable
- Remarks on result:
- other: estimated by BIOWIN v4.1 (US EPA): the fields "%Degr.", "St. dev.", "Parameter" and "Sampling time" cannot be filled in
- Validity criteria fulfilled:
- not applicable
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Result of estimation software BIOWIN v4.10 [by US-EPA (EPI Suite v4.1)]: According to the Linear Model, as well as to the Non-linear Model, allyl alcohol is biodegrading fast. The Ultimate Biodegradation Timeframe is given in weeks, whereas the Primary Biodegradation Timeframe shows days for the substance. MITI Linear Model, as well as the Non-linear Model, states that allyl alcohol is readily biodegradable. Under anaerobic conditions allyl alcohol is suspected to be biodegraded fast. The overall ready biodegradability prediction for the substance allyl alcohol is YES.
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: peer-reviewed handbook
- Qualifier:
- according to guideline
- Guideline:
- other: no data
- Deviations:
- not specified
- GLP compliance:
- not specified
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge (adaptation not specified)
- Duration of test (contact time):
- 28 d
- Value:
- 82 - 86
- Remarks on result:
- other: aerobic removal exceeds 82-86% of theoretical BOD after 2-3 weeks
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- readily biodegradable
- Conclusions:
- In an aerobic biodegradation study using activated sludge, allyl alcohol degraded 82-86% after 2-3 weeks; moreover, a BOD of 1.6 to 1.8 g/g [Heukelekian and Rand (1955); Bridie et al. (1979)] and a ThOD of 2.21 g/g [Bridie et al. (1979)] indicate that the experimental result seems to be correct: allyl alcohol is readily biodegradable.
