Cobalt in Hard-metals and Cobalt Sulfate, Gallium Arsenide, Indium Phosphide and Vanadium Pentoxide (Iarc Monographs on the Evaluation of the Carcinogenic Risks to Humans) 1st edition

This monograph evaluates the evidence of carcinogenicity of metallic cobalt particles with or without tungsten carbide, to which workers in the hard-metal industry are exposed, and of cobalt sulfate and other soluble cobalt (II) salts. It also evaluates three other particulate compounds: gallium arsenide and indium phosphide, which are used extensively in the microelectronics industry; and vanadium pentoxide, a contaminant at facilities refining and processing vanadium-rich ores, and in various workplaces that use oil-fired boilers and furnaces.
