1. EXECUTIVE SUMMARY This CICAD on vanadium pentoxide and other inorganic vanadium compounds was based on a review of human health concerns (primarily occupational) prepared by the United Kingdom’s Health and Safety Executive (HSE, in press). This review focuses on exposures via routes relevant to occupational settings, but it also contains environmental information. Data identified as of November 1998 were covered. A further literature search was performed up to May 1999 to identify any additional information published since this review was completed. An Environmental Health Criteria monograph (IPCS, 1988) was used as a source document for environmental information. As no more recent source document was available for environmental fate and effects, the literature was searched for additional information. Information on the nature of the peer review and availability of the source documents is presented in Appendix 1. Information on the peer review of this CICAD is presented in Appendix 2. This CICAD was approved as an international assessment at a meeting of the Final Review Board, held in Helsinki, Finland, on 26–29 June 2000. Participants at the Final Review Board meeting are listed in Appendix 3. The International Chemical Safety Cards on vanadium trioxide (ICSC 0455) and vanadium pentoxide (ICSC 0596), produced by the International Programme on Chemical Safety (IPCS, 1999a,b), have also been reproduced in this document. Vanadium (CAS No. 7440-62-2) is a soft silverygrey metal that can exist in a number of different oxidation states: !1, 0, +2, +3, +4, and +5. The most common commercial form is vanadium pentoxide (V2O5; CAS No. 1314-62-1), and this exists in the pentavalent state as a yellow-red or green crystalline powder.
