Background: Shoe making is among the oldest traditional occupations. Hazardous chemical substances such as adhesives containing benzene and toluene are used in the manufacturing process. Due to the lack of studies on exposure of shoemakers to benzene and toluene in Iran, this study was organized aiming at evaluating occupational exposure and risk assessment in shoemakers. Materials and Methods: Overall, 48 shoemakers (12 workshops) in East Tehran were selected randomly for this study. Personal exposure of shoemakers in four different task groups of cutting, modeling, fitting and finishing was examined during three consecutive months (October, November and December) with different climatic conditions. Sampling and analysis of samples were based on an OSHA method (Method No.12). Results: The results of personal monitoring of subjects ’ exposure to benzene and toluene in each of the three consecutive months (Mean ± standard error) were 1.10 ± 0.11, 1.37 ± 0.14 and 1.52 ± 0.18ppm, 11.78 ± 1.77, 14.87 ± 1.71 an
