Road traffic is a major source of atmospheric pollution, especially in urban areas, contributing significantly to particulate matter (PM) emissions. While electric vehicles (EVs) help reduce exhaust emissions, they do not substantially address non-exhaust emissions (NEEs), such as brake wear dust (BWD), which remains significant PM, particularly environments. This study investigates at preliminary level the environmental fate BWD, studying laboratory scale its mobility and behaviour unsaturated saturated porous media, simulate subsoil aquifer conditions. produced through friction between pads rotors during deceleration, can settle on road surfaces, posing risks soil water quality runoff infiltration.
