Every year, billions of vehicles worldwide shed an estimated 6 million tonnes of tire fragments.
These tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food. Researchers in South China recently found tire-derived chemicals in most human urine samples.
These tire particles are a significant but often-overlooked contributor to microplastic pollution. They account for 28 percent of microplastics entering the environment globally. --
