Abstract

CONTENT OF HEAVY METALS IN THE SOILS OF THE CEREŞNOVĂŢ RIVER BASIN

Within the present study was assessed the content of heavy metals in the soils of the Cereşnovăţ river basin, and particularly within the forest ecosystem “Racovăţii de Sud”. The content of heavy metals in the soils of the Cereşnovăţ river basin was determined according to the methods recommended by ICP Forest program after soil types, on fixed layers of 10 cm. Based on the outcomes was observed that the accumulation of heavy metals is dependent and influenced by various factors: human factor, the distance from the pollution source, the terrain, the physical properties of migration of heavy metals and soil type. It was found that low - medium content of heavy metals in the soils of Cereşnovăţ river basin presents favorable ecological conditions to biotic components of the forest ecosystem “Racovăţii de Sud”. Results allow us to conclude that the health of biodiversity and functioning capacity of the ecosystem are not threatened by edaphic factor. Keywords: heavy metals, pollution, soil, forest ecosystem.
