Effect of environment pollution by heavy metals on their accumulation in flower plants
The aim of the investigation was to estimate pollution levels of the upper soil horizon and Ni and Cu accumulation as well as Mn content in the leaves of Vaccinium myrtillus, V. vitis-idaea, V. uliginosum, Empetrum hermaphroditum, Calluna vulgaris, Arctostaphylos uva-ursi, Ledum palustre, Chamaeneri...

| Summary: | The aim of the investigation was to estimate pollution levels of the upper soil horizon and Ni and Cu accumulation as well as Mn content in the leaves of Vaccinium myrtillus, V. vitis-idaea, V. uliginosum, Empetrum hermaphroditum, Calluna vulgaris, Arctostaphylos uva-ursi, Ledum palustre, Chamaenerion angustifolium, Eriophorum polystachion, Rubus chamaemorus, Cornus suecica, Solidago lapponica, which are flowering plants of pine forests in Kola Peninsula (Russia) exposed to industrial pollution. It was shown that Ni and Cu contents increased in all components of forest ecosystems with decreasing the distance from the smelter. There exists a linear correlation between the active forms of Ni and Cu in the upper soil horizon and their concentrations in plant leaves (r = 0.92-1.00, p < 0.05). Accumulation of Ni and Cu in plants was species-specific. Ni moves easier than Cu from polluted soil to the overground part of plants. Mn concentration in the leaves is a supplementary indicator of stress in the higher plants as well as of pollutant concentrations, especially by heavy metals. |
