Considerable amounts of pollutants are generated by more than one billion registered vehicles worldwide. While the emissions. related to exhaust gasses and tire wear were addressed extensively, the released brake wear debris and its impact were studied to a considerably lesser extent. Our previous work indicated that the released wear debris can have negative impact on environment.
