Applicant's summary and conclusion
- Conclusions:
- The data on environmental distribution of dichloromethane obtained from the level III fugacity model confirms that dichloromethane does not degrade fast and depending on various emission scenarios, most of dichloromethane will be phisically removed (advected) from the environment.
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.
