Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Any other information on results incl. tables

Neutron activation analysis revealed no enhanced content of SASIL in tissues compared to surrounding sediment. After 4 weeks exposure, 238 mg SASIL/kg were measured in tissues, and after additional 7 days exposure in SASIL-free sediment, 147 mg Sasil/kg were determined.
