Scientists call for urgent research on tyre particles as leading source of microplastics

Scientists are urging more research into tyre particles, which are now identified as the leading source of microplastics. A new study shows these particles make up nearly a third of all microplastics and may pose unique risks to health and the environment. Tyre particles differ from traditional microplastics in size and chemical composition. They contain harmful additives that can leach into ecosystems, affecting waterways, soil, and food chains. The study calls for these particles to be treated as a distinct environmental threat. Researchers from multiple countries recommend forming an international panel to address the issue of tyre particles. They emphasize the need for coordinated global efforts to understand and mitigate the impact of these pollutants.
