Applicant's summary and conclusion
- Executive summary:
Mackay fugacity modelling (level 3) indicates that, taking into account degradation and using model inflow parameters all compartments exhibit some degree of sensitivity according to what compartments receive emissions. Emissions to water remain primarily in this compartment, whereas emissions to air and soil partition to all compartments.
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.
