Yes, non-stick pans can release microplastics, but the numbers you’ve mentioned—9,000 microplastic particles from a single scratch and over 2 million from a broken coating—can vary based on the condition, quality, and usage of the pan.
1. Non-Stick Coatings and Microplastics:
Non-stick pans are typically coated with polytetrafluoroethylene (PTFE), commonly known by the brand name Teflon. PTFE is a polymer, and when it degrades, it can release microplastics. The coating is durable when intact, but over time, scratches and wear can damage the surface.
2. Scratching and Microplastic Release:
When a non-stick pan gets scratched, especially with metal utensils, small particles of the coating can break off. Repeated scratching can indeed contribute to microplastic pollution. Studies have shown that minor damage can release thousands of small polymer particles. The figure of 9,000 microplastic particles is based on studies showing that a single scratch can release this amount, but the actual number depends on factors like the severity of the scratch, the damaged area, and the quality of the coating.
