| chemical and ecological effects of contaminated tunnel wash water runoff to a small norwegian stream. | cleaning and washing of road tunnels are routinely performed and large volumes of contaminated wash water are often discharged into nearby recipients. in the present study, traffic related contaminants were quantified in tunnel wash water (the nordby tunnel, norway) discharged from a sedimentation pond to a nearby small stream, arungselva. in situ size and charge fractionation techniques were applied to quantify traffic related metal species, while pahs were quantified in total samples. all meta ... | 2010 | 20547412 |
