Railway pollution - sources, dispersion and measures. A literature review (English)
Abstract [sv]

Pollutants in the railway environment emanate both from emissions from the

traffic and from the treatment of embankments to control weeds and prevent

timber sleepers from rotting. During the last years particular attention has

been paid to air pollution from rail traffic. High concentrations of inhalable

particles (PM10) have been observed mainly in tunnel environments. This report

is an international literature survey aiming at compiling and synthezising

current knowledge concerning railway pollutants, their sources, dispersion and

possible measures to reduce pollution. The study does not take into account

point sources in connection to accidents or diesel powered railway traffic.

The main railway pollutants are identified as inhalable particles, herbicides,

PAH and heavy metals. Except for a compilation of current knowledge about

these pollutants, some lack of knowledge has been identified. More

comprehensive studies of railway pollution and pollutant dispersion in air,

soil and water are absent in the literature. For water recipients and other

sensitive environments exposed to railway pollution as well as for certain

rail stretches with potential considerable emissions, this kind of studies

should be well advised. Especially, understanding the relationship between

emission, dispersion and exposure is important if we are to take suitable

measures. An important knowledge gap concerns the formation, properties and

potential health effects of inhalable particles from railway traffic.

Inhalable particles in our ambient air are considered one of our most serious

health-related environmental problems. Therefore there is a need for increased

knowledge about railway contributions and health effects of pollutants in

different environments as well as about which measures are most effective.
