Abstract

Airborne dust in foundries contains significant quantities of quarts, which is known to cause silicosis. Starting from the finding of alarming increase of the pneumoconiosis in factories, we made a cross-sectional study in 3 foundries, to determine the chest x-ray alterations due to Si O₂ particles.
A short variant of the questionnaire recommended by CE was used for the clinic data and occupational history. Chest x-ray was made and interpreted in order to identify pneumoconiosis, according to standard procedures. 925 workers were medically examined and provided occupational histories. The data were analyzed adjusting to age and smoking habit.
Analyses of data according to ILO scheme, found 176 men with small pneumoconiotic shadows of profusion under 1 and 49 x-ray with small spots q, r of category 1 or 2 conglomerate opacities, 2 silicotuberculosis, 6 tuberculosis and 2 pulmonary chronic fibrosis of Welders. All patients were than examined in the Occupational Medicine Hospital in Cluj-Napoca. There were confirmed 9 patients with small spots p, category 0/1, 41 silicosis with small opacities q, r profusion 1-3, 1 tuberculosis and 1 pulmonary chronic fibrosis of welders.
It is very important that industry focuses on reducing respirable quart concentration in specific jobs and to follow-up the workers exposed to dust.
