HEAVY METALS IN SOILS AND VASCULAR PLANTS OF THE BELLSUND AREA (SPITSBERGEN)

摘要

The basic properties of soils in major physiographic units of the area were examined. The content of several heavy metals (Cu, Zn, Mn, Pb, Cd, Co) in soils and selected vascular plants were determined, also. The relationship between the content of metals in plants and the content of metals in soils was determined. The content of metals in both soils and plants had a particular order, although not the same all the time. It usually opens with manganese and closes with cadmium. The plants of the Sileneacaulis (L.) type are characteristic of high values of manganese. Positive correlations were observed between the content of copper in soils and the Saxifraga cespitosa (L.) and Saxifraga oppositifolia (L.) plants. A negative correlation was observed between the content of copper in soils and the Dryas octopetala (L.) plants.
