“…Dunner (1945) described the clinical and radiological findings in men exposed to graphite through unloading ships for periods of about 20 years. Lister (1961) reported a man who had been turning and grinding synthetic graphite bars for 17 years. Gloyne, Marshall, and Hoyle (1949) and Harding and Oliver (1949) reported some fatalities in workers exposed to a mixed dust containing graphite during manufacture of crucibles.…”

. Graphite pneumoconiosis. In this survey, which is the first of its kind in the graphite industry, 344 workers in a large mine in Ceylon were investigated for pulmonary lesions; 22*7 % of them had radiographic abnormalities, which included small rounded and irregular opacities, large opacities, and significant enlargement of hilar shadows. They had worked considerably longer in the industry and were, on average, older than the rest. Only 192 % of the affected workers had respiratory symptoms, of which dyspnoea and cough were the most frequent. Digital clubbing was seen in 21P9 %.In Graphite is crystalline carbon. It is also known as plumbago as it was originally mistaken for lead. It is used in lead pencils, foundry linings, paints, electrodes, and dry batteries, and in making crucibles for metallurgical purposes. Finely powdered graphite is also employed as a lubricant. The best quality product on the world market comes from Ceylon and Madagascar. The Ceylon mineral may reach a degree of purity as high as 98 % and is especially in demand for purposes where quality graphite is required, as in the manufacture of crucibles.
