BORTNIK L. The ecological estimation of urbolandscape under the contents of heavy metals in soil- plant system (as example for Kharkiv city).

Kharkiv city. Ecological estimation of pollution of ter-ritory. Bioindication analyses, express-method, x-ray -spectral analysis. x-ray spectrometer СРМ-25, athom-absorbtional spectrometer С-115М.The heavy metals content was investigated in both soil and plants of Kharkіv forest parks. The ecological estimation has been carried out for pollution contents in the top layer of soil. The geochemical areas were mapped out for distribution of main pollutants in ecosystem. The condition of the plants was estimated by means of methods of bioindica-tion. The system analysis of the pollutant distribution in soil-plant chain was carried out. The results made it pos-sible to investigate the pollutant distribution in the urboe-cological subsystems of Kharkіv city. Sphere of use are ecology, monitoring of urban grounds, agriculture
