Air pollution induced changes were observed both in plant communities and in soil chemistry in forest ecosystems near the nickel-copper smelter in the Kola Peninsula, Russia. All measured forest plant community parameters describing their floristic composition and structure were affected by pollution. Heavy metals were significantly concentrated in organic(More)
The effect of industrial pollution with emissions from the Severonikel Copper-Nickel Plant (SCNP) on soil microbial communities of forest biogeocenoses has been studied taking into account their relative location under tree crowns (near the stem, in the undercrown area, or under gaps in the canopy). The results show that increasing technogenic pollution(More)
Carbon dioxide emission (CO2) is the most important part of carbon turnover, which characterizes the biological activity of soils. This parameter was investigated in background ecosystems and those that have undergone atmospheric contamination in the subarctic zone of the Kola Peninsula, the large industrial region. The Pechenganikel’ plant located in the(More)
In spite of reduction in atmospheric emission, current state of forest ecosystems within the impact zone of Severonickel enterprise still reflects the entire spectrum of anthropogenic digression stages. As the distance to the enterprise grows shorter, structural-functional changes in forest communities are manifested in dropping out of mosses and lichens,(More)
Soil emission of carbon dioxide, the key component of carbon cycle and the characteristic of soil biological activity, has been studied in background and polluted ecosystems in the Kola subarctic, the large industrial region of Russia. Long-term air pollution by emissions of "Pechenganikel" smelter, the largest source of sulphur dioxide and heavy metals in(More)
