The Effect of Heavy Metals Transport from Contaminated Soil to "Opuntia Vulgaris Mill" with the Use of Biologics

Cleansing technogenically contaminated soils with the help of special plants is a more cost-effective and environmentally friendly method. When applying this technique, a special place is occupied by a decrease in the concentration of heavy metals, especially the concentration of its mobile forms in technogenically contaminated soil. In this case, a certain proportion of heavy metals and their mobile forms pass (transported) from the soil to the plant and the soil becomes less safe in an ecological sense, which is very important for its practical use. To enhance the effect of biological purification of the soil environment, it is very important to simultaneously enhance the accumulation effect in the soil itself of heavy metals using biological preparations. The purpose of this work was to identify the effect of accumulation in the soil using the plant as an indicator. The studies were carried out in the industrial zone of the Kala Absheron peninsula of Azerbaijan with the use of the plant "Opuntia Vulqaris Mill" under the conditions of biological activation of technogeneously polluted soil with the use of the "Biomax" preparation moved with treated organic fertilizer. The concentration of heavy metals was measured using a XRF X-ray fluorescence spectrometer. The analysis of the obtained data showed that the biological activation of technogenically polluted soil medium even in an insignificant level (the level of biological activation was only 1.36%) increased the effect of accumulation of 1.34 times heavy metals from the soil due to the effect of transport of these metals from soil to plant. Research of this effect is very important when using technogenically contaminated soils, under cultivated plants, which is not food
