Abstract Most of the compounds whose carcinogenicity is evaluated in this volume are poorly soluble solid materials. They are deposited in particulate form in the lung where they may be retained for a long period of time while exerting their toxic properties. Workers in the hard-metal industry may be exposed to cobalt in hard metals (with or without tungsten carbide); gallium arsenide and indium phosphide are used in the semi-conductor industry and vanadium pentoxide is mainly used in the production of metal alloys. Conclusions of this monograph: cobalt metal without tungsten carbide, cobalt sulfate and other soluble cobalt(II) salts are possibly carcinogenic to humans (Group 2B); gallium arsenide is carcinogenic to humans (Group 1); indium phosphide is probably carcinogenic to humans (Group 2A); vanadium pentoxide is possibly carcinogenic to humans (Group 2B).
