Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- (Q)SAR
- Adequacy of study:
- weight of evidence
- Study period:
- 2021
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- QSAR prediction from a well accepted model
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- BIOWIN estimates the biodegradation of organic substances. The model is part of the EpiSuite program of the US-EPA. Estimations are made with BIOWIN version 4.10
In the BioWin program, the conclusion on ready biodegradation is estimated from two models.
• Biowin3 estimates complete ultimate biodegradation in a typical aquatic environment
• Biowin5 predicts biodegradability in the Japanese MITI i.e. OECD 301C test
BioWin gives a YES prediction for “Ready Biodegradation” if both of the following conditions are met:
• the ultimate biodegradation (Biowin3) results in weeks, days to weeks or days
• MITI linear model (Biowin5) probability is ≥ 0.5 - GLP compliance:
- no
- Specific details on test material used for the study:
- not applicable QSARS
- Oxygen conditions:
- aerobic
- Duration of test (contact time):
- 28 d
- Parameter:
- other: QSAR BIOWIN V4.10
- Remarks on result:
- other: QSAR prediction no quantitative result is avialable
- Results with reference substance:
- Validity of the model: see QMRF and QPRF
- Conclusions:
- Fatty acids C16-18, saturated and unsaturated, isopentyl esters, is estimated to be readily biodegradable in a standard MITI test (OECD 301C) by the BIOWIN QSAR model.
- Executive summary:
The aerobic biodegradation of Fatty acids C16-18, saturated and unsaturated, isopentyl esters, was estimated by BIOWIN version 4.10.This QSAR model is included in the EPI Suite programs developed by Sycracuse Research Corporation for US-EPA. The conclusion of BIOWIN is that Fatty acids C16 -18, saturated and unsaturated, isopentyl esters is estimated to be readily biodegradable in a standard MITI test (OECD test guideline 301C). The mineralisation is estimated to take days to weeks and the primary degradation occurs within a timeframe of days. Test results on biodegradation are not available. The calculated result can be used for classification and risk assessment.
Reference
For the dermination of the biodegradation in water a QSAR system is used. The conclusion of BIOWIN is that Fatty acids ,C16 -C18 saturated and unsaturated isopentyl esters is estimated to be readily biodegradable in a standard MITI test (OECD test guideline 301C)
Description of key information
Biodegradation for Fatty acids C16-C18, and C18 unsaturated isopentyl esters was
estimated with QSARS.Fatty acids C16-C18, and C18 unsaturated isopentyl esters was found to be readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
