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

Natural surface soils in Southern Norway are strongly contaminated by metals from atmospheric deposition. Except from local pollution with Cu, Ni and to a limited extent Pb around the town of Kristians and, this large-scale contamination can be ascribed to long-range atmospheric transport from other...

Description
Summary:Natural surface soils in Southern Norway are strongly contaminated by metals from atmospheric deposition. Except from local pollution with Cu, Ni and to a limited extent Pb around the town of Kristians and, this large-scale contamination can be ascribed to long-range atmospheric transport from other parts of Europe. Zinc, As, Cu, and Pb are all found in excessive concentrations in the surface layer of natural soils throughout the region, and in particular within a zone of about 20 to 40 km from the coast. In this zone the elements appear tat the following concentrations or higher in the A sub(0) layer (typical levels in other parts of Norway little affected by air pollution in parantheses): Zn, 120(30) mg kg super(-1); As, 4(0.5) mg kg super(-1); Cd, 2(0.2) mg kg super(-1); Pb, 160(15) mg kg super(-1). Possible harmful effects to soil biological processes of this contamination cannot be excluded.
