چکیده مقاله:

Research has shown that dermal exposure to multi-ring aromatic compounds can lead to skin and systemic absorption of these materials. Due to the low vapor pressure of these materials, the main cause of occupations exposure in certain occupations is skin contact. The production of bitumen products due to the presence of polycyclic aromatichydrocarbons (PAHS) in the bitumen of the production line has a health hazard. It is noteworthy that skin rashes with polycyclic aromatic hydrocarbons in this industry can cause skin problems in the workplace. This study evaluates skin exposure to these compounds in the lSO—industry using DREAM method. Methods: In this study, we evaluated 120 different workers in different groups of four waterproofing plants with aromatic hydrocarbons. In the DREAM method, five types of skin exposures including distributing exposure, transitional exposure, displacement exposure, probable exposure,and actual exposure are assessed and calculated using tables and software. Results: The highest transmission and distribution exposure was found to be 28.81 (19.5) and 9.1 (4.86), respectively, in the manufacturing jobs and bitumen ponds.Displacement exposure was observed only in roll-up and labeling groups. The areas of the hand and shoulder were more likely to be exposed than other parts of the body. The probable and real exposure to the head and arm was lower than elsewhere. In all occupations, the most important exposure to the skin was transmission and distribution exposure.Conclusion: DREAM method can be used to assess skin exposures. In this study, the actual and probable skin exposure levels were approximately the same, indicating a lack of proper skin protection in the workforce. Unhealthy behaviors, non-use of personal equipment and inappropriate connection are the causes of this finding.
