Every day, numerous cars and trucks are wearing on Norway´s almost one hundred thousand kilometers of road: Asphalt wear on the tires, the tires wear on the asphalt, exhaust flows out from the vehicles and all is shrouded by road dust, until a rainfall cleanses the air, leaving all the dust and particles in the ditch. Most places, the dirty rain water is directly discharged into the environment. However, some of the newly built roads have sedimentation dams, where the road runoff rest for some weeks while rubber, soot and dust sink to the bottom, protecting the surrounding environment from road contamination.
Sedimentation dams have caught researchers interest. Sedimentation dams are urban habitats for a range of plants and animals, but it appears these dams also contain high levels of pollutants. Laboratory tests have shown that such contaminants have hazardous effects on for instance dragonflies and other insects.
