Soil surface geochemical anomaly around the copper-nickel metallurgical smelter.
The soils were sampled from the center of airborne contamination caused by long time activity of a copper/nickel smelter complex in the Kola Peninsula, Russia.
The soil specimens were taken from an area about 250 km2, which included the town of Monchegorsk, with frequency of 1 sample (plot) per 3 km2 and heavy metals nickel, copper, cobalt, chromium, lead, cadmium, strontium, iron, manganese and arsenic were measured.
The soil surrounding the Smelter, including the inhabited territory of the town, was found to be contaminated by nickel and copper to levels 450-and 250 times higher in comparison to the background, respectively.
These soils were found to be extremely toxic and represented a severe threat to human health.
Elevated concentrations of iron and arsenic caused by smelter emissions were found too.
