Title: Phytoremediation of radiocesium-contaminated soil in the vicinity of Chernobyl, Ukraine

Abstract

Remediation of soil contaminated with {sup 137}Cs remains one of the most challenging tasks after the Chernobyl 1986 accident. The objectives of this research were to (1) identify extractants that may be used to solubilize {sup 137}Cs in soil solution, (2) study the effect of soil amendments on {sup 137}Cs accumulation by plants, and (3) evaluate the applicability of phytoextraction for environmental restoration of soil contaminated with {sup 137}Cs. The availability of {sup 137}Cs to the plants in Chernobyl soil was limited, because this radionuclide was tightly bound to exchange sites of soil particles or incorporated into the crystalline structure of primary and secondary minerals. Out of 20 soil amendments tested to increase {sup 137}Cs desorption/solubility in the soil, ammonium salts were found to be the most practical soil amendment that can potentially increase {sup 137}Cs bioavailability. Among the screened plants, Amaranth cultivars had the highest {sup 137}Cs accumulation. Three sequential crops of Indian mustard grown in one vegetation season at the experimental plot resulted in a small decrease of {sup 137}Cs specific activity within the top 15 cm of soil. Further improvements are necessary to make phytoremediation technology a feasible option for restoration of {sup 137}Cs-contaminated territories.
