Distribution of heavy metals in plant communities of the West Siberian Arctic and Subarctic

The paper presents the results of comprehensive studies on problem formation a deposit heavy metals in plant communities West Siberian Arctic and Subarctic. regularities concentration redistribution soil-plant system have been revealed. Excessive accumulation by different species is limited selectivity root absorption relation to certain elements, therefore it important calculate coefficient biological absorption. interrelation between intensity recreational loading change nature, grass cover structure.Among identified pollutants that accumulate plants group microelements (Pb, Sr, Cu, Zn, Ni ). It shown linear dependence “soil-plant” observed only range low concentrations ground growing. With high reverse occurs. Formulated, justified tested methodical approaches preparation complex long-time observations natural ecosystems.
