Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
Slags, steelmaking, vanadium is a sparingly soluble UVCB substance that upon dissolution may release minor amounts of vanadium and insignificant amounts of other elements. Thus, regarding the environmental fate, vanadium is the moiety of concern. Only one reliable study (Klimisch 2) on the biota-to-soil-accumulation factor (BSAF) of vanadium for terrestrial plants is available, reporting BSAF values smaller than 0.1 for Lactuca sativa, Solanum tuberosum and Lolium perenne grown in a sandy or loamy soil amended with V2O5 up to 500 mg V/kg dw (Vangheluwe et al., 2003). The absence of vanadium accumulation in terrestrial plants (BSAF << 1) is also supported by data for Brassica oleracea and Glycine max grown in soils amended with VOSO4 and NH4VO3, respectively (Kaplan et al., 1990; Wang and Liu, 1999). No data are available for bioaccumulation of vanadium in terrestrial invertebrates.
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.
