Abstract:

This paper presents a laboratory experiment which aims to identify the main pollutants that appear to affect large areas of farmland around the aluminum plant in Slatina. After conducting a germination test using several species of plants, there were selected two of them, which developed more rigorously and produced a higher biomass. The experiments were made with sunflower (Helianthus annuus L.) and rye (Secale cereale L.), which were sown in pots with unpolluted reference soil, polluted soil amended with expanded clay and polluted soil amended with expanded clay inoculated with mychorriza fungi. This paper presents results on sunflower. The experiment was conducted under controlled conditions in a vegetation room and soil parameters were determined before and after running the experiment (pH, electrical conductivity, humidity, soil respiration, mineral forms of N, assimilable P and the metals content. In the plant material (roots, stems, leaves) the following parameters were determined: metal content, lipid peroxidation (LP), chlorophyll a and b, carotenoids and protein content. It was observed to what extent inoculated fungi (Glomus intraradices) influenced heavy metal absorption by plants. The study indicated an increase of the transfer coefficients from the soil in the plant under the influence of the formed mychorriza, in the case of metals V, Zn, Cu and a decrease in the case of Cr, Mn, Ni , Pb, U. The conclusion of this study was that mychorriza fungi have a role in the accumulation of heavy metals in the rhizosphere, a phenomenon known as phyto-stabilization. Keywords: heavy metals, poly-element soil contamination, Helianthus annuus L., phyto-stabilization
