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

Microplastics have become a significant environmental problem in recent years. These tiny plastic particles, which are usually less than 5 mm, are ubiquitous in oceans, rivers and even in the air we breathe. They come from various sources, including the decomposition of large plastic waste, synthetic fibres in clothing and micro beads in personal care products.

The impact on marine life and ecosystems is well documented. Studies have shown that the intake of chemicals by marine animals leads to physical damage and potential exposure to chemicals. With the growing awareness of microplastics, researchers are discovering new, often surprising ways in which these particles enter the environment.

Overview of the new study and its results

A remarkable study showed that about 9,100 microplastic particles can be released by a single scratch on an anti-stick pan. This discovery highlights a previously overlooked source of microplastic pollution: everyday kitchen utensils. Under the direction of researchers from the University of Newcastle and Flinders University in Australia, the study investigated the wear of Teflon-coated cookware and showed that even minor damage can contribute significantly to the environmental impact of microplastics. In addition to a single scratch, significant damage to these coatings can release up to 2.3 million particles, which illustrates the extent of this hidden source of pollution.

Understanding microplastics: Definition and impact

Microplastics are plastic particles that are smaller than 5 mm. They can be primary (intentionally small, such as micro beads) or secondary (caused by the decay of larger plastics). Its effects are far-reaching and affect marine life and, to an increasingly, human health. Microplastics are present in seafood, drinking water and air and cause concern about physical blockages, chemical contamination and inflammation in organisms. Non-stick-coated pans are mostly polytetrafluoroethylene (PTFE), a PFAS compound whose potential health risks have triggered a debate due to their persistence and possible toxicity.
