Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- STP modeling was conducted by means of an internationally accepted QSAR, i.e., QSAR STPWIN™ of EPI Suite™ v.4.11. STPWIN™ uses several outputs from EPI Suite™, this program predicts the removal of a chemical in a typical activated sludge-based sewage treatment plant. Values are given for total removal and three processes that may contribute to removal: biodegradation, sorption to sludge, and air stripping. The program assumes a standard system design and set of default operating conditions.
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6

Results and discussion
Percent distribution in media
- Other distribution results:
- The results show that 93-25% of the substance was removed during wastewater treatment by adsorption to sludge, using the default value of 10000 hr for Bio P,A,S.
Applicant's summary and conclusion
- Conclusions:
- The results show that 93.25% of the substance was removed during wastewater treatment by adsorption to sludge, using the default value of 10000 hr for Bio P,A,S.
- Executive summary:
The removal of the substance during sewage treatment was estimated using the STPWIN™ module of EPI Suite™ v.4.11. STPWIN™ uses several outputs from EPI Suite™, this program predicts the removal of a chemical in a typical activated sludge-based sewage treatment plant. Values are given for total removal and three processes that may contribute to removal: biodegradation, sorption to sludge, and air stripping. The program assumes a standard system design and set of default operating conditions. For the present calculations, these default operating conditions were used. The results show that 93.25% of the substance was removed during wastewater treatment by adsorption to sludge.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
