| Abstract | Abstract Background: 4,4 - Methylendiphenyl diisocyanate(MDI), is the most widely used chemical in the manufacturing of polyurethanes (a field of plastic industries), and it is one of the major causes of the occupational asthmas. Objective: Assessing the MDI concentration in air and also evaluating the effect of this chemical on eyes, skin, respiratory and gastrointestinal systems in workers of a foam producing section in a car manufacturing company. Methods: The effects of MDI on skin, eyes, respiratory and gastrointestinal systems were evaluated in two 40-person groups of exposed and unexposed workers and the MDI concentration in air was determined. The data were analyzed using t-Student test, pair-t-test, λ2 test, Regression Analyze, and correlation test. Findings: MDI concentration was lower than the threshold limit value while the local ventilation and air conditioning systems were both on, however, it was higher than the expected value when both systems were switched off. Our results showed that the presence of symptoms such as coughing, smart pain and dryness of skin, and the smart pain and itching of eyes in exposed group were significantly different from those in unexposed group(P | en |
