| Abstract |
Autopsied lungs from 29 hard rock miners were investigated to determine possible relationships between pathology and radiology findings, and occupational exposure. There was a good agreement between radiological and pathological findings. Positive correlations were seen between hydroxyproline (as an index of fibrosis), silica dust, non-silica inorganic dust, radiographic category of pneumoconiosis and pathologic grade of silicosis. Smokers lost on average seven years of life compared to non-smokers. Silica appeared to be concentrated in lungs and lymph nodes. Silica in the lymph nodes was on average 2.4-fold higher than in the lungs. Other findings are discussed. |
