In Reply: Exposure to Hard Metal

Abstract

In my recent editorial, I offered the scientifically conservative view that the cause of the parenchymal lung disorders which have been associated with exposure to hard metal (tungsten carbide with binders including cobalt) remains uncertain. Dr. Abraham, citing some of his own work and the classic inhalation studies at Saranac Lake, 1 Schepers GWH The biologic action of particulate cobalt metal. AMA Arch Indust Health. 1955; 12: 127-133 PubMed Google Scholar argues that the pathogenic role of cobalt has been established. His basis for this is the similarity between histologically distinct giant cell reactions seen in some reported cases of hard metal disease and the pathologic response to cobalt metal dust reported by Schepers. 1 Schepers GWH The biologic action of particulate cobalt metal.
