Large amounts of vanadium ions are found in a few organisms, possibly as a toxin. The oxide and some other salts of vanadium have moderate toxicity. Particularly in the ocean, vanadium is used by some life forms as an active center of enzymes, such as the vanadium bromoperoxidase of some ocean algae.

Vanadium bromoperoxidase is a haloperoxidase , used to synthesize halogenated organic compounds associated with defense and pigmentation in seaweeds and marine algae. It is the source of the bulk of organobromine compounds in the ocean. This enzyme class is unusual in that it has an absolute requirement for the transition metal vanadium , which is present as vanadate . Vanadium bromoperoxidases have been found in bacteria, fungi, and marine macroalgae seaweeds which produce brominated compounds. It has not been definitively identified as the bromoperoxidase of higher eukaryotes, such as Murex snails, which have a very stable and specific bromoperoxidase, but perhaps not a vanadium dependent one. ref PMID 19363038 Review of vanadium dependent bromoperoxidases in nature ref The enzymes catalyses the oxidation of bromide ions by hydrogen peroxide , which results in the specific bromination of certain eletrophilic organic substrates. The enzyme will form singlet oxygen in the absence of the appropriate organic substrates.

Naturally occurring vanadium V is composed of one stable isotope sup 51 sup V and one radioactive isotope sup 50 sup V with a half life of 1.5 10 sup 17 sup years. 24 artificial radioisotope s have been characterized in the range of mass number between 40 and 65 with the most stable being sup 49 sup V with a half life of 330 days, and sup 48 sup V with a half life of 15.9735 days. All of the remaining radioactive isotopes have half lives shorter than an hour, the majority of them below 10 seconds, the least stable being sup 42 sup V with a half life shorter than 55 nanoseconds, with all of the isotopes lighter than it, and none of the heavier, have unknown half lives. In 4 isotopes, nuclear isomer metastable excited states were found including 2 metastable states for sup 60 sup V , which adds up to 5 meta states. The primary decay mode before the most abundant stable isotope sup 51 sup V is electron capture . The next most common mode is beta decay .
