%X Background: Formaldehyde is a chemical active material with stabilizer and disinfectant applications in pathology laboratories. One of its side-effects is respiratory problems which were studied in this research. Materials and Method: Thirty-eight subjects exposed to formaldehyde and 23 unexposed personals at pathological laboratories were studied with regard to their respiratory symptoms and functions. ¡°Exposure Questionnaire¡±, spirometry and environmental measurement were used for this purpose.Results: Nasal and throat burning were achieved the highest incidence; and other symptoms including hoarseness, cough and dyspnea in exposure group, respectively. Many symptoms were significantly associated with time-pattern and/or exposure intensity.Conclusion: Unchanged spirometric values could be due to intermittent exposure. However, regarding to the high incidence rate of respiratory symptoms and high concentration of the formaldehyde in laboratories, effective ventila
