Iv. Shtangeeva et al., Decontamination of polluted urban soils by plants. Our possibilities to enhance the uptake of heavy metals, J RAD NUCL, 249(2), 2001, pp. 369-374
Pot experiments were carried out to assess the influence of two plant speci
es on chemistry of polluted and unpolluted urban soils. Change in pH and ac
id neutralization capacity of the soils, as well as variations in elemental
composition of soil leachates and in total concentrations of elements in t
he soil were studied by INAA and ICP-AES. Concentrations of 28 elements in
plants were determined by INAA. Cultivation of plants led to significant ch
ange in soil parameters. In particular, acid neutralization capacity of pol
luted soil increased, resulting in increase in element uptake.
