In the years 1987-1995 studies were carried out on the content of Cu, Mn, Zn, Pb and Cd in plants and soil in the Bellsund area, Western Spitsbergen. For the studies the author used predominating species of vascular plants, bryophytes and lichens collected from beaches littoral planes, valleys, slopes and mountain peaks. Some plant species, largely bryophytes and lichens, were shown to contain increased amounts of Zn, Pb and Cd, whilst in others Cu deficiency was found. This paper is summing up studies concerning the content of Cu, Mn, Zn, Pb and Cd in plants of Western Spitsbergen, which were conducted over many years.
The contents of copper, manganese, zinc, lead and cadmium have been determined in plants of the Spitsbergen tundra, collected at Calypsostranda, Lyellstranda and Chamberlindalen in 1987. Five species of vascular plants, four species of mosses and fourteen species of lichens have been investigated. Manganese content in all the studied plants falls in the physiological limits of this element. Appreciable concentrations of copper, and zinc exceeding the physiological concentrations of these elements and presence of lead and cadmium have been shown for many plants.
53 soil samples collected in the Bellsund Region in Western Spitsbergen were examined. An acid-resistant strain difficult to identify was isolated and recognized as Mycobacterium friburgensis. 54.7% of isolated strains were acid-resistant and growing at 25˚C only. They were microorganisms at borderline of Mycobacteria and Actinomycetes. Other microorganisms isolated in the studied soil samples were bacilli (55.7%) and coccaceae (15.4%).
