    Streszczenie angielskie: Impairment of pulmonary function in cement mill workers has been previously reported without considering a variety of parameters that can help evaluate more thoroughly the effect of cement dust on the respiratory system. In addition, an integrated approach has not been considered to assert the involvement of respiratory muscles. Therefore, in the present study spirometry and surface electromyography (SEMG) of intercostal muscles were used for indicating pulmonary impairment. In this study, a group of 50, apparently healthy volunteers, male cement mill workers aged 20-60 years with exposure of 13 years on average, were randomly selected. They were matched with another group of 50 control healthy male subjects in terms of age, height, weight and socioeconomic status. Both groups met the standard exclusion criteria. Spirometry was performed on an electronic spirometer, while SEMG of intercostal muscles was performed by using a chart recorder. The results demonstrated statistically significant reduction in lung function parameters i.e., force vital capacity (FVC) (p 0.0005); force expiratory volume in first second (FEV1) (p 0.0005); peak expiratory flow (PEF) (p 0.005); and maximum voluntary ventilation (MVV) (p 0.0005) in cement mill workers, when compared with controls. However, the FEV1/FVC ratio was significantly higher (p 0.025) in cement mill workers. Similarly, the parameters obtained from SEMG of intercostal muscles, i.e. number of peaks (NPO) (p 0.0005); maximum peak amplitude (MPA) (p 0.0005); peak to peak amplitude (PPA) (p 0.0005)...
