Applicant's summary and conclusion
- Conclusions:
- The European background concentration of aluminium oxide was found about 98 to 101 g/kg sediment d.w. (ca. 10%), which corresponds to 26.0 to 26.7 g Al/kg sediment d.w..
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
