Results and discussion
Adsorption coefficient
- Type:
- log Koc
- Value:
- 2.425
Any other information on results incl. tables
As the substance is dissociated under environmental relevant pH conditions, the estimated Koc-value for the undissociated acid is not valid for environmental assessment purposes.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not applicable
- Remarks:
- parameter was calculated
- Conclusions:
- The calculated Log Koc between water and soil was 2.425 (Epiwin Version 2.0, Syracuse Research Corporation, Environmental Science Center Merill Lane,
Syracuse, NY 13210, 1996). - Executive summary:
The calculated Log Koc between water and soil was 2.425 (Epiwin Version 2.0, Syracuse Research Corporation, Environmental Science Center Merill Lane, Syracuse, NY 13210, 1996). As the substance is dissociated under environmental relevant pH conditions, the estimated Koc-value for the undissociated acid is not valid for environmental assessment purposes.
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).
