 Silicosis is an occupational disease reported in silica, stone & mining industry. No proper report on workers in industries using silica in stones and

coal has been done from Chhattisgarh till date. Detailed history, lung functions and chest x–ray were done. Diagnosis was made on the basis of
radiology & history. Data analysis was done with the help of the statistical package for social sciences software. The Chi–square test was used for
determining the relationship between qualitative data and descriptive statistics was used where required. Out of the total 16 reported cases, 13 had
respiratory symptoms. Radiological abnormalities were noted in all. Lung functions revealed obstruction in 25%, restriction in 12.5 %, while
mixed ventilatory defects in 62.5% subjects. 16 cases of silicosis and silicotuberculosis were reported. They had high respiratory morbidity
(81.25%), cough and dyspnea being predominant symptoms. Duration of exposure correlates with radiological findings and increased incidence of
silicosis.
