Graphite pneumoconiosis.

Carbon pneumoconiosis in a synthetic graphite worker.

Prevalence o f Pulmonary Tuberculosis in Graphite Miners by

Pulmonary tuberculosis is relatively frequent in workers exposed to silica or a mixed dust containing silica (Marchand, 1972). This increased susceptibility has been shown in relation to silica itself (Hunter, i962),coal (Rivers, James, Davies & Thompson, 1957) and talc (Siegal, Smith & Grecnburg, 1943). Since graphite too contains a proportion of silica which is about 2 % in the purest commerc...

A cohort study of graphite workers in Sri Lanka.

A cohort of workers from a graphite mine in Sri Lanka was studied in 1987, 1990 and 1993. Radiographic lesions were found in 8.5%, 8.9% and 4.1% of the workers in these respective rounds. When workers with radiographic lesions were clinically examined, a total of 18 cases of graphite pneumoconiosis and seven cases of active pulmonary tuberculosis were detected in the three rounds. The prevalenc...

Pneumoconiosis due to graphite dust.

Lassar Dunner (1945a) recorded the clinical and radiological findings in five men who had been exposed to " pure graphite " dust. They had been exposed for 17, 18, 20, 20, and 34 years respectively, and no other dusts were known to have been implicated. Three of the men had cough, sputum, and dyspnoea; the other two had no complaints. Radiographs showed reticulation with nodulation, and the que...
