Description of key information
Bioaccumulation: Low potential for bioaccumulation - BCF value of 400 taken as representative from literature data on vanadium
Key value for chemical safety assessment
- BCF (aquatic species):
- 400 dimensionless
Additional information
In accordance with REACH Regulation 1907/2006 (Annex IX - 9.3.2, Column 2) examination of bioaccumulation can be waived if the substance has a low potential for bioaccumulation based on a Log Kow of <3. The experimentally determined Log Pow is -1.33, implying a low potential for bioaccumulation.
In general, organisms do not concentrate or accumulate vanadium from environmental media to a high degree, and there is no indication of biomagnification in food chains. Miramand & Fowler (Miramand P, Fowler S, Bioaccumulation and transfer of vanadium in marine organisms. In:Vanadium in the environment. Part 1: Chemistry and biochemistry.New York, NY, John Wiley & Sons, pp. 167–197, 1998) have reviewed reports of levels of vanadium in marine organisms and calculated concentration factors for components of a typical marine food chain based on average seawater concentrations of 2 ng/g. Concentration factors for primary producers ranged from 40 to 560, for primary consumers from 40 to 150, for secondary consumers from approximately 20 to 150, and for tertiary consumers from 2 to 400. One study has attempted to quantify vanadium uptake from sediment using48V and the ragwormNereis diversicolor. Vanadium was accumulated from the sediment with a low transfer factor of approximately 0.02 (Miramand P.Contribution à l’étude de la toxicité et des transferts du vanadium chez quelques organismes marins. Doctoral Thesis, Université des Sciences et Techniques du Languedoc, 115 pp.1979). Comparison of uptakes via food and directly from water showed that invertebrates accumulated vanadium primarily from food (Miramand P, Fowler S. Bioaccumulation and transfer of vanadium in marine organisms. In:Vanadium in the environment. Part 1: Chemistry and biochemistry, John Wiley & Sons, pp. 167–197, 1998). However, Aascidians have been known to accumulate large residues of vanadium (Henze M, Die vanadium Verbindung der Blutkorperchen.Hoppe-Seyler’s Zeitschrift für Physiologische Chemie, 72: 494–501,1911). More recently high vanadium accumulation has been demonstrated in polychaetes of the genusPseudopotamillawhile polychaetes of other genera did not accumulate the metal (Ishii T, Nakai I, Numako C, Okoshi K, Otake T. Discovery of a new vanadium accumulator, the fan wormPseudopotamilla occelata.Naturwissenschaften, 80: 268–270, 1993).
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).
