Results and discussion
% Degradation
- Key result
- Parameter:
- probability of ready biodegradability (QSAR/QSPR)
- Value:
- 0.091
- St. dev.:
- 0
- Remarks on result:
- not readily biodegradable based on QSAR/QSPR prediction
- Details on results:
- Calculation using BIOWIN V4.10 gives MITI probability of biodegradation 0.0910, predicted not to be readily biodegradable.
Totxtree (decision treeapproach) gave the result of Class 2 persistent chemical.
The results are in alignment and therefore the conclusion is drawn that the substance will not be readily biodegradable.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- Calculation using BIOWIN V4.10 gives MITI probability of biodegradation 0.0910, predicted not to be readily biodegradable.
Totxtree (decision treeapproach) gave the result of Class 2 persistent chemical.
The results are in alignment and therefore the conclusion is drawn that the substance will not be readily biodegradable. - Executive summary:
Calculation using BIOWIN V4.10 gives MITI probability of biodegradation 0.0910, predicted not to be readily biodegradable.
Totxtree (decision treeapproach) gave the result of Class 2 persistent chemical.
The results are in alignment and therefore the conclusion is drawn that the substance will not be readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
