Paper Straws Found to Contain Cancer-Linked 'Forever Chemicals', Expert Warns
On.cc · 1 SOURCESabout 2 hours ago2 MIN
Summary
Foreign research has revealed that up to 90 percent of paper straws contain PFAS, the synthetic "forever chemicals" associated with cancer risks including kidney and testicular cancer. Dr. Wu Shi-ying, a lecturer in food and health sciences at the Technological and Higher Education Institute of Hong Kong (THEi), explained that PFAS compounds, made from carbon and fluorine atoms, are used as waterproof coatings to prevent paper straws from softening quickly in drinks . The expert warned that prolonged soaking and chewing on straws can damage the PFAS coating, increasing chemical leaching into beverages. While reusable stainless steel straws remain the only material not found to contain PFAS, an industry innovator named Don has developed eco-friendly paper straws using alternative waterproofing technology that eliminates the need for these harmful chemicals entirely .
Key Points
- Foreign studies detected PFAS in up to 90 percent of paper straws tested, with the chemicals linked to kidney and testicular cancer risks
- PFAS consists of carbon and fluorine atoms combined into highly stable synthetic compounds that resist natural degradation in the environment
- Dr. Wu Shi-ying from THEi noted that longer soaking times and chewing behavior both damage the waterproof coating, accelerating PFAS leaching
- The research found PFAS contamination is not unique to paper straws, as plastic and bamboo straws also contained trace amounts of these chemicals
- Don, a chemical industry veteran, created PFAS-free paper straws using water-based coating technology that achieves 20-40 percent less paper consumption
Why It Matters
Hong Kong's extensive use of paper straws at restaurants and beverage shops means residents are potentially exposed to PFAS with every commute refreshment. Since these chemicals persist in the body and environment, accumulated exposure through daily straw use could pose long-term health risks that warrant immediate consumer attention and regulatory review .
