The impact of the long-term exposure of industrial aerosols on clinical and functional indices of the broncho-pulmonary system in aluminum smelter workers
It was found that the appearance of respiratory diseases among workers was established to be associated with the impact of aerosols with the complex chemical composition, exceeding corresponding MAC. Among respiratory diseases in workers there were detected predominantly chronic non-obstructive bronchitis - 59.15%, and chronic obstructive pulmonary disease (COPD) - in 35.2% of cases. In the analysis of spirometric indices of examined patients the vast majority (76.3%) of them showed disturbances of the bronchial patency of mild to moderate degree of the pronouncement. As a result of the implementation offlexible bronchoscopy there was established the presence of a diffuse lesion of bronchi with a predominance of subatrophic and atrophic processes in the mucosa. It was found that under the increase of the concentration of HF in the air of industrial premises the probability of bronchial obstruction and deterioration of the tracheobronchial patency in aluminum smelter workers was established to elevate.
