Decontamination of polluted urban soils by plants. Our possibilities to enhance the uptake of heavy metals

Pot experiments were carried out to assess the influence of two plantspecies on chemistry of polluted and unpolluted urban soils. Change in pHand acid neutralization capacity of the soils, as well as variations in elementalcomposition of soil leachates and in total concentrations of elements in thesoil were studied by INAA and ICP-AES. Concentrations of 28 elements in plantswere determined by INAA. Cultivation of plants led to significant change insoil parameters. In particular, acid neutralization capacity of polluted soilincreased, resulting in increase in element uptake.
