Abstract
An occupational health survey was conducted in three large cemented tungsten-carbide plants. The field investigation comprised an engineering study of the working conditions, and particularly the dustiness of operations, in the various plants, and a medical and dental study of the health of the workers. Chemical examination was made of the dust content of the air samples secured at various operations to evaluate the dust content of the air and to determine the chemical composition of the dust, particularly the cobalt (7440484) content. The regions of the body where examiners consistently obtained abnormal findings on physical examination were the conjunctivas and the upper respiratory tract. Abnormal conditions of the gingivae were found among three fourths of those examined, and in one half of the mucous membrane was abnormal to some extent.
