Differences in lung function and prevalence of pneumoconiosis between two kaolin plants.
To investigate the origin of differences in previously published pulmonary function studies of workers in kaolin plants in Georgia, spirometric and radiographic data collected in a cross sectional survey of two large plants were analysed. As compared with workers in plant 2, workers in plant 1 had a 2.7-fold greater prevalence of pneumoconiosis and a mean 0.361 decrement in adjusted forced vita...

Workers in the more heavily exposed jobs of milling, bagging, and loading showed a prevalence rising from 6% in those with between five and 15 years' exposure to 23...
متن کاملInhalation of china stone and china clay dusts: relationship between the mineralogy of dust retained in the lungs and pathological changes.
A combined clinical, radiological, pathological, and mineralogical study was undertaken on 62 cases referred to the Medical Research Council Pneumoconiosis Unit by the Cardiff Pneumoconiosis Panel as Cornish china clay workers. Considerable pathological lesions were found in the lungs, both nodular and interstitial fibroses being present. Some men had worked with china stone but others had work...

All developed complicated pneumoconiosis, diagnosed in two cases at necropsy, in one by lobectomy, and in one radiologically. Two of the patients were found at necropsy also to have peripheral squamous lung cancer. The clinical and histological features of the disease resembled ...
