Abstract

Objectives: Bisphenol A, or BPA, is a chemical component in polycarbonate plastic with which many people come into contact every day. A great deal of controversy has arisen over its safety since this material, which is known to disrupt the human endocrine system and cause neurological difficulties and cancer, is commonplace in beverage containers, food can liners, and receipt paper rolls. In this study, we determined the levels of exposure to BPA of workers in the service industry depending on the number of receipts contacted. Methods: The participants were 16 male and 18 female workers employed in the service industry. Using a questionnaire, we investigated general and job characteristics. Urine samples were collected and analyzed by the LC-MS/MS technique after enzymatic hydrolysis and solid phase extraction (SPE). Results: The geometric mean (GM) concentration of urinary BPA from all subjects was 1.02 ng/ml. Workers were exposed significantly to more BPA according to the number of receipts they contacted, their work experience, and working hours per day. The BPA concentration of those who touched more than 100 receipts per day was 3.09 ng/ml, while that of the other participants was 0.61 ng/ml. It was shown that wearing gloves can protect from BPA exposure. Conclusion: We determined the urinary BPA concentrations of workers in service industry and found that the contact with receipts could increase the BPA exposure of service workers.
