PHYTOREMEDIATION OF ARSENIC-CONTAMINATED SOILS AMBROLAURI MUNICIPALITY

Abstract
The phytoremediation technology has the best potential for cleaning the pollutants from the soil because it is environmentally friendly and inexpensive method. The study aims to introduce phytoremediation methodology at the selected sites of arsenic contaminated soils of the Racha-Lechkhumi and Kvemo Svaneti regions to restore soil fertility. For phytoremediation three plants Amaranthus gangeticus, Chenopodium album and Helianthus annuus were selected for the accumulation and translocation of heavy metals from the contaminated soil. For this study Ambrolauri municipality of the agricultural sites of the village Abari and Likheti was selected due to arsenic contamination. The concentration of arsenic was determined before and after the phytoremediation. The seeds of selected plants were treated with the bioactivatorbiorag to increase the green mass of the plant. Plants were sown in May and harvested in August and October; plants were harvested in their raw state. After drying, the plants (which part root, shoot or whole plant) were processed and the total form of arsenic was determined. Several parameters were calculated for plants that have an influence on phytoremediation potential, such as arsenic concentration, bioconcentration factor (BCF), translocation factor (TF) and Biological accumulation coefficient (BAC), whose values are >1. This indicates that the selected plants which plant have more potential can accumulate and remove arsenic from contaminated soil, which is a necessary condition for the successful implementation of phytoremediation. Phytoremediation efficiency equal to 32.5% (extracted by the plant) was determined, and the amount remaining in the soil - 67.5%. Keywords - Pollution, Arsenic, Soil, Phytoremediation, Biorag.
