The widespread use of Bisphenol A (BPA) and Bisphenol S (BPS) in thermal paper products, such as receipts, has sparked concern about the potential health risks associated with these chemicals. As endocrine disruptors, BPA and BPS can interfere with the body’s hormonal system, leading to a range of health problems.
Chemical Structure and Function
BPA and BPS are synthetic compounds used in the production of thermal paper products. They are added to the paper coating to facilitate the thermal printing process, which involves heat-activated chemicals that produce the printed image.
Health Risks and Associated Diseases
Exposure to BPA and BPS has been linked to various health problems, including:
• Hormonal imbalances and endocrine disorders
• Increased risk of breast and prostate cancer
• Metabolic issues, including weight gain and obesity
• Reproductive problems, such as infertility and birth defects
Exposure Routes and Sources
BPA and BPS can enter the body through:
• Skin contact with contaminated thermal paper products (e.g., receipts, tickets, labels)
• Ingestion of food and drinks packaged in BPA-lined containers
• Inhalation of particles released during thermal printing
Thermal Paper Products and Exposure Risks
Receipts are the most common thermal paper product, but other sources of exposure include:
• Movie and concert tickets
• Parking tickets
• Labels and tags
• Some food packaging materials
Reducing Exposure and Mitigating Risks
To minimize exposure to BPA and BPS, consider:
• Requesting digital receipts or opting out of paper receipts
• Avoiding skin contact with thermal paper products
• Using gloves when handling thermal paper products
• Advocating for BPA-free and BPS-free thermal paper alternatives
• Limiting use of thermal paper products in your daily life
Conclusion and Future Directions
The potential health risks associated with BPA and BPS in thermal paper products are a growing concern. By understanding the sources of exposure and taking steps to reduce our exposure, we can mitigate the risks and promote a healthier environment.
