Cinder track
With cinder track is in common usage often the default 400-meter oval extensive career of athletics - stadium called. The name is derived from the original floor covering, which is still widely used today. This consists of a bed of gravel or slag with a rolled-in top layer made of a mixture of ash , red sandstone or sand . Since athletics in its current form comes from England, the dimensions of the cinder tracks are adapted to the English ones and accordingly standardized internationally (instead of 1/4 mile = 402.336 m) 400 m, instead of 333.33 m (3 laps = 1 km).
In the narrower sense, the floor covering is called a cinder track to distinguish it from the more modern tartan floorings made of plastic. However, the older tartan tracks in particular contain mercury in quantities that are considered carcinogenic and may therefore only be disposed of with the greatest possible precaution.
Although the Federal Institute for Sports Science has had a specialist committee for sports facilities since it was founded in 1970, it has not succeeded in bringing the quality of the cinder track surfaces into a DIN standard. For example, copper slag ( pebble red , dioxin pollution) and arsenic have repeatedly led to sports fields being closed due to the ash deposits .
