Abstract:
Background and Objectives
Chemical exposure for the shoe makers has been created health hurdle. This exposure mainly occurs in the gum process which workers have been exposed to various solvents such aromatic hydrocarbons and n-hexane. This study was conducted to evaluate occupational exposure in some shoe makers for the co-exposure of benzene, toluene, xylene and n-hexane in order to monitor their health condition.
Methods
In this study 73 shoemakers of 18 workshops in Tehran were studied. Occupational exposure to aromatic hydrocarbons (benzene, toluene and xylene) and n-hexane was measured using NIOSH method No.1501 and 1500 in summery (September and October) and wintry season (January and February) respectively.
Results
The results show amount of occupational exposure to studied compounds (benzene, toluene and xylene) and n-hexane in warm and cold season (Mean±standard error) were 2.33±0.07, 9.48±0.27, 2.2±0.01, 3.64±0.11 and 3.1±0.07, 11.11±0.23, 2.2±0.01, 4.4±0.11 ppm respectively and in the colder months were significantly higher than the warmer months (p
Conclusion
When the cumulative exposure to aromatic compounds and n-hexane were higher than Occupational exposure Limit (OEL) accepted by Iran, there is a probable neurotoxic risk as a common effect for studied solvents. Therefore, the use of appropriate control methods is important to reduce solvents exposure of adhesives.
