Any other information on results incl. tables
Henry's Law constant was calculated according to Bond SAR Methode
volatilisation from water:
half-life from model river: 3.611E+004 days (ca. 99 y)
half-life from model lake: 2.626E+005 days (ca. 719 y)
Applicant's summary and conclusion
- Conclusions:
- The Henry constant was 1.39E-009 atm-m3/mole (calculated according to Bond SAR Method, Epiwin Version 2.0, Syracuse Research Corporation, Environmental Science Center Merill Lane, Syracuse, NY 13210, 1996).
- Executive summary:
The Henry constant was 1.39E-009 atm-m3/mole (calculated according to Bond SAR Method, 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
