Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Bioaccumulation data of Ti in plants have been generated by Caille et al. (2005) (read-across approach with titanium). After 54 days of exposure of different plant species (rape, Brassica napus; cabbage, Brassica oleracea; red fescue, Festuca rubra) the authors noticed very similar low concentrations of Ti in the leaves, i.e. between 0,7 and 2,4 mg Ti/kg dw, resulting in very low biota-to-soil-accumulation factors (BSAF) between 0,0002 and 0,0008 kg/kg. 

Key value for chemical safety assessment

Additional information

Bioaccumulation of Ti are very low and therefore a significant transfer in the food chain is not expected. Indeed, data on the bioaccumulation of Ti clearly show that a significant bioaccumulation in plants is not likely to occur.
