Heavy metal pollution by long range atmospheric transport in natural soils of Southern Norway

摘要: Natural surface soils in Southern Norway are strongly contaminated by metals from atmospheric deposition. Except local pollution with Cu, Ni and to a limited extent Pb around the town of Kristiansand, this large-scale contamination can be ascribed long-range transport other parts Europe. Zinc, As, all found excessive concentrations layer natural throughout region, particular within zone about 20 40 km coast. In elements appear at following or higher A0 (typical levels little affected air parantheses): Zn, 120(30) mg kg−1; 4(0.5) Cd, 2(0.2) Pb, 160(15) kg−1. Possible harmful effects soil biological processes cannot excluded.
