Characterization of abrasion-induced metal emissions from rail transport into the environment

In terms of environmental protection, rail transport is advantageous compared to other modes of transport. Nevertheless, particulate emissions, mainly
caused by abrasion, are released into the environment during railway operation. However, only a few studies have been published on the particle size
distribution, particle mass and chemical composition of these abrasions. Metal particles, such as copper and iron, are expected to be emitted into the
environment as those metals are commonly used in rail transport components (e.g. wheel, rail, brakes and contact wire).
The scope of the present research is to obtain detailed information on the particle mass, particle size distribution, chemical composition and morphology of
the source-specific abrasion emissions.
