Applicant's summary and conclusion
- Conclusions:
- A Mackay Level III fugacity model predicts that release of the substance to the water compartment results in distribution exclusively to water (56.8 %) and sediment (43.2 %). Distribution to air and soil is negligible.
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.
