[Determination of the pneumoconiosis hazard in the cork industry].

The AA. have carried out an epidemiological investigation in order to control the prevalence of chronic respiratory diseases on a group of 385 people working in several cork industries in North Sardinia. At the same time an environmental investigation has been carried out. Standard questionnaire (CECA questionnaire) for chronic bronchitis and pulmonary emphysema, standard chest X-ray film, spyrographic investigation, ECG and sputum analysis for acid resistent bacteria have been used for epidemiological investigation. Environmental dust concentration and individual dust exposure, environmental concentration of sulphur oxides, nitrogen oxides, carbon mono- and dioxide, ammonia nad microclimatic conditions have been studied. Examination of medical data shows only a low degree of respiratory pathology in contrast with results of other authors, probably because of different methods used for epidemiological investigation and data interpretation and because of different environmental and working conditions.
