    Abstract

    It has been well documented that the natural arctic system is being polluted by anthropogenic atmospheric heavy metals. This research looked at local scale variation in heavy metal concentration of top soils and two species of two dwarf shrub species, Empetrum. nigrum and Vaccinium vitis-idaea. It was found that there was some contamination of the soil by Cu and Zn. The concentration of the soil was mostly dependent upon the amount of organic matter. The root system was shown to not depend on any of the environmental variables measured, but did retard movement of Pb further into the plant tissue of both species. Metal concentrations were significantly higher in the east facing slope with exception to Zn and Pb levels. Changes in the tree structure down the slopes had little to no effect on the metal uptake to the shrubs. Active uptake was identified in the species for the micronutrients and less for the non-essential heavy metals. Further research is suggested to be into the variation in geological addition of heavy metals to the soil and changes in heavy metal concentration with soil depth.
