[Occupational exposure of workers in chemical factors and selected parameters of the respiratory system].

Workers employed in chemical factories are chronically exposed to harmful substances present in the air of the occupational environment. The aim of this paper was to find out whether this situation produces adverse effects on the respiratory system despite the observance of admissible concentrations of toxic substances in the air. Spirometric values such as FVC1 and FEV1%FVC were measured in 647 workers.
