Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Bioaccumulation: aquatic / sediment

Description of key information
Due to the in-solubility of slags in octanol and water, determination of log Kow can be considered as technically not feasible and a theoretical log Kow of slags would be very low. The highly insolubility of slags, tin-smelting in water leads to the behaviour of this substance similar to that of sand or gravel. Even in case of uptake of all detected metals by organisms (as a worst case), an accumulation can be excluded.
A cross-check with the bioaccumulative behaviour of the corresponding metals and metal oxides via ECHA´s website for registered substances revealed that none of the metals/metal oxides has been identified to show potential for bioaccumulation. Relevant exposure of aquatic compartment is unlikely regarding the use of slags, tin-smelting – therefore releases of slags, tin-smelting to the environment in general, and to the aquatic compartment can be excluded.
Against this background determination of bioaccumulation in aquatic species does not need to be conducted under Regulation (EC) No 1907/2006 (REACH).
Key value for chemical safety assessment
Additional information
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.
