Ecological Systems and Devices Annotation << Back Effectivity of Lead and Camdium Phytoextraction from Model Polluted Soil by the Cultivated Oat Petukhov A.S., Kremleva T.A., Khritokhin N.A., Pervukhina E.D. This study is devoted to revealing the features of Pb and Cd accumulation in the cultivated oat in conditions of organogenic and mineral substrate (soil) model pollution by various concentration of individual metal. Pollution was applied in the form of lead acetate and cadmium sulfate in the amount of 0, 50, 100, 200, 500 and 0, 2, 5, 10, 20 mg/kg (calculated for metal), respectively. The duration of vegetation was 14 days, after which the content of metals in the underground and aboveground parts of the cultivated oat, mobile and acid-soluble forms of metals in soil were determined by atomic absorption spectroscopy. Multiple accumulation of Pb and Cd in oats relative to the control was revealed (up to 112 and 470 times, respectively). Migration of metals was more pronounced in the underground part of oats (up to 10 times compared to the above-ground part) and in mineral substrate conditions (up to 15 times compared to the organogenic substrate). The mobility of metals in the soil is higher in the mineral substrate than in the organogenic one, the mobility of Cd is higher than that of Pb. Accumulation, translocation, migration to the above-ground part of the plant and disturbances of the barrier mechanism of the root system with increasing pollution were more pronounced for Cd than for Pb. The underground and above-ground (to a lesser extent) parts of oats can serve as indicators of Pb and Cd content in the soil, and a high degree of Cd extraction from the soil is promising for the use of oats in phytoremediation.
