Unlabelled:
The aim of this study was to evaluate the influence of the work place environment on the function of the respiratory system.
Material:
Study covered 211 male from Mechanical Plant of Plock Refinery (M.P. group 1) and the control group consisted of 53 male employed in Design Office (D.O. Group II). Group I was exposed to toxic substances (NO2, SO2, dust, manganese and iron oxides).
Methods:
Lung function tests were performed using laboratory "Compact-Lab" (JAEGER). The FVC, FEV1, FEV1%FVC, PEF, FEF50 were obtained from flow-volume curve and TGV, Rt measured using plethysmography method. Information concerning symptoms and cigarette smoking were obtained from questionnaire designed for this study.
Results:
Mean values of respiratory indices were within normal range and did not differ between groups. The percentage of abnormal results was similar in groups. Air flow limitation (FEV1%FVC < 70%) was observed in 15.2% of total. Smokers have had significantly lower indies of air flow limitation but still within normal range. Symptoms (cough, expectoration, dyspnea) were equally frequent in M.P. and D.O. and significantly more frequent in smokers.
Conclusion:
In our study we did not find the influence of work place environment on the function of the respiratory system.
