Assessment of the green spaces' state in the impact zone of the Pechenganikel smelter, the Murmansk region

The study of the state green spaces in urbanized areas is important due to their sanitary, hygienic and aesthetic role harsh climatic conditions Arctic. objects research were urban-type settlement Nikel (the Murmansk region). assessment distribution tree shrub species by categories life was carried out; revealed damage leaves atmospheric emissions, insects fungi. A high degree from pollution noted birch, mountain ash bird cherry; aspen up 85 % damaged aphids; mechanical trunks about 26 surveyed trees; 5 trees have frost cracks trunk. In course a comparative chemical composition birch growing territory forest ecosystems along gradient impact zone Pechenganikel plant, it found that concentrations pollutants technologically disturbed exceed background values. Birch southern direction plant accumulate higher Ni, Cu, Pb, Co, Fe than western northern directions. 2019, heavy metals increased compared previous period (2004). urban area, content exceeds not only values regional background, but also levels identified pollution. Concentration coefficients Cc show abnormally for Fe; maximum are Ni Co.
