Adsorption of Tuberculin by Coal Dust [PDF]
Epidemiology and Infection, 1931 While investigating the effects of silica dust and coal dust respectively in the production of respiratory disease in coal miners, we have been struck by the sharp contrast between silicotic coal miners in South Wales as compared with silicotic gold miners in South Africa in their respective liability to pulmonary tuberculosis.
