The use of heavy metal accumulating plants for detoxication of chemically poluted So ILS

Inglés. The studies conducted from 1997 to 1999 in a vegetation hall were performed as a pot experiment on ordinary silt soil. Jerusalem artichoke, maize, Sida hermaphrodita rusby, amaranth and hemp were used as indicator plants. The results confirmed, great diversification of the element contents which depends not only on the species but also on the part of individual plants. Analysis of the data revealed also another dependence: increased concentration of heavy metals in the soil corresponded to a higher content of heavy metals in the plants. Significant differences in this respect were observed for the plant species grown in unpolluted or differently contaminated soil.
