THE USE OF PLANTS ACCUMULATING HEAVY METALS FOR DETOXICATION OF CHEMICALLY POLLUTED SOILS
Jacek Antonkiewicz, Czesława Jasiewicz
ABSTRACT
The studies conducted from 1997 to 1999 in a vegetation hall were performed as a pot experiment on ordinary silt with cation exchange capacity (CEC) of 81.1 cmol (+) · kg–1, pHKCl = 6.0 and organic C content of 9.5% serving as soil. Jerusalem artichoke, maize, Sida hermaphrodita Rusby, amaranth and hemp were used as indicator plants. The results confirmed, implied earlier, great diversification of the element contents which depends not only on the species but also on the part of plants. Analysis of the data revealed also another dependence: increased concentration of heavy metals in the soil corresponds to higher content of heavy metals in the plants. Significant differences were observed for the plant species from unpolluted and contaminated at various levels treatments.
Key words: detoxication, heavy metals, plants, polluted soils.
