Tire Dust Makes Up the Majority of Ocean Microplastics

  Meanwhile, British firm Emissions Analytics spent three years studying tires. The group found that a single car’s four tires collectively release 1 trillion “ultrafine” particles for every single kilometer (0.6 miles) driven. These particles, under 100 nanometers in size, are so tiny that they can pass directly through the lungs and into the blood. They can even cross the body’s blood-brain barrier. The Imperial College London has also studied the issue, noting that "There is emerging evidence that tire wear particles and other particulate matter may contribute to a range of negative health impacts including heart, lung, developmental, reproductive, and cancer outcomes.”

  It’s an emissions problem that won’t go away with the transition to EVs, either. According to data from Emissions Analytics, EVs tend to shed around 20 percent more from their tires due to their higher weight and high torque compared to traditional internal combustion engine-powered vehicles.

  Great
