Respiratory Tract Disorders Associated with Changes of the Mucous Membrane in Workers often Exposed to Pathological and Toxic Factors

This article is investigating changes in the mucous membrane of the respiratory tract in workers who are often exposed to pathological and toxic factors. Research methods and materials: Air sampling was performed by aspirator and gas analyzer. Collected air was checked for chemical composition. Results and discussions: Air sampling of the working area detected toxic substances such as dust, soot and toxic gases: SO2, N2O5, N2O4, NO2, N2O, CO and H2S. Concentrations of these toxic substance and gases varied from 0.06-15.8 mg/m3. Mechanisms of toxic effects causing occupational disorders by various substances and chemicals described. Conclusions: Respiratory tract disorders including chronic bronchitis, allergic bronchitis, chronic obstructive pulmonary disease and lung cancer in workers exposed to pathological and toxic factors have been described.
