||Evaluation of workers' exposure to methylene diphenyl diisocyanate (MDI) in an automobile manufacturing company, Iran
||2006, Vol.12, No.4, p.443-449. 22 ref.
||The objective of this case-control study was to evaluate the inhalation exposure to methylene diphenyl diisocyanate (MDI) among 39 employees working in the window assembly unit of an automobile manufacturing company in Iran. Controls consisted of 117 unexposed workers in other departments of the plant. MDI was determined with a UV-VIS spectrophotometer at 590nm. Lung function was assessed with a digital spirometer. The average concentration of MDI in the window fixation and window glue workplaces were 34.53 and 27.37µg/m3, respectively, which were lower than the threshold limit value recommended by the ACGIH of 51µg/m3. However, there was a significantly higher frequency of respiratory symptoms and a significantly lower lung capacity in the exposed group compared to the unexposed group.
