A new study shows that more than 9,000 microplastic particles can be released by a scratch. Here is the source and what you need to do

This study identifies scratches on non-stick cookware as the main source for the release of microplastics. Everyday activities such as cooking with metal utensils or cleaning scratched pans can lead to abrasions in which microplastics are released. These particles can be flushed into water systems when washing or reach the air as dust and thus contribute to environmental pollution. Studies show that the durability of non-stick coatings is crucial to reducing this pollution. This suggests that the way these products are used and maintained must be rethought.

The study focuses on non-stick cookware, especially on pans with teflon coating, but their effects also extend to other scratch-sensitive plastic objects. Cutting boards, utensils and even plastic containers used in food preparation can also release microplastics under similar conditions. Outside the kitchen, items such as combs, brushes and plastic enclosures of household appliances can help if they are rubbed off. This suggests that any plastic product exposed to wear could be a potential source of microplastics and requires a closer look at the material selection.

The researchers used advanced techniques to measure the release of microplastics. They simulated scratches on te-finn-coated pans in a controlled laboratory environment, thus imitating real use. Using Raman imaging and spectroscopy, they were able to accurately quantify the particles released from a single crack (about 9,100) and a broken coating (up to 2.3 million burnings simulated over 30 seconds). This consistent approach provided clear and reproducible evidence and underpinned the need to deal with the release of microplastics from household items.

This study advises consumers to be careful when using non-stick cookware. Scratched pans can not only lose their functionality, but also release invisible pollutants. Therefore, a more gentle way (e.g. B. Avoidance of metal utensils) or the use of alternatives such as stainless steel or cast iron displayed. For manufacturers, this shows that they need to develop more sustainable coatings or explore PFAS-free options to minimize environmental and health risks. The findings could also stimulate innovations in the area of cookware that resists wear without releasing microplastics.

The research was conducted by teams from the University of Newcastle and Flinders University and in the Science of the Total Environment (Volume 851, 10. December 2022). It is entitled “Raman imaging for the identification of Teflon microplastics and nanoplasty, which is released from non-stick cooker,” and is available via ScienceDirect. This journal pee reviewed by experts ensures the credibility of the study and makes it a reliable source of understanding of microplastic pollution from kitchen utensils.

When an anti-stick pan is scratched, consumers should consider replacing them, especially if it is frequently used or comes into contact with food to limit the exposure to microplastics. By using cooking utensils made of wood or silicone and gentle cleaning, you can extend the life of a pan and reduce particle release. Switching to scratch-resistant alternatives such as glass, ceramics or stainless steel offers a longer-term solution and minimizes environmental and potential health problems.

As microplastic pollution receives more and more attention, this study underlines how urgent it is to tackle everyday sources such as non-stick coated cookware. Consumers can play their part by opting for sustainable, environmentally friendly products, while manufacturers need to develop innovations to reduce the loss of microplastics. Policymakers could also consider provisions on PFAS in household goods. By continuing our research and building on results like this, we can better protect ecosystems and human health, paving the way for a more sustainable future.
