The paper "Wear and Tear of Tyres: A Stealthy Source of Microplastics in the Environment" by Pieter Jan Kole, Anse J. Löhr, Frank G. A. J. Van Belleghem, and Ad M. J. Ragas reviews the impact of tyre wear and tear on the environment, particularly the release of microplastics. The authors estimate that per capita tyre wear and tear emissions range from 0.23 to 4.7 kg/year, with a global average of 0.81 kg/year. Car tyres are a significant source of microplastics, contributing 100% of emissions from this source, followed by airplane tyres (2%), artificial turf (12-50%), brake wear (8%), and road markings (5%). The emissions and pathways depend on local factors such as road type and sewage systems. Tyre wear and tear contributes to 5-10% of the total global amount of plastics in the oceans and 3-7% of particulate matter (PM2.5) in the air, indicating its potential health impact. The paper also discusses the entry of tyre wear and tear into the food chain and the need for further research to assess human health risks. The authors conclude that tyre wear and tear is a stealthy source of microplastics that requires increased awareness, knowledge closure, and creative technical solutions to address effectively.The paper "Wear and Tear of Tyres: A Stealthy Source of Microplastics in the Environment" by Pieter Jan Kole, Anse J.
