  4. Abstract:
  5. Calendula alata, Amaranthus chlorostachys and Chenopodium album plants were tested for their potential to uptake and accumulate stable cesium and lead from solutions in a period of 15 days. The plants were grown hydroponically and placed in solutions containing CsCl and Pb(C2H3O2)2 at three different concentrations (0.6, 2 and 5 mg L-1). Cs transfer factors in different solutions were more than 1 with the highest level of 2.45 for 2 mg L-1 of CsCl and Pb(C2H3O2)2 in mixed solution. According to its uptake from the environment, cesium effect on anatomical and ontogenical structure of plant was studied. Aerial organs of Chenopodium album were investigated for modifications studies. Observation showed that tissue structures of these organs had not changed at all and only xylems are expanded due to fight against tension and cells store cesium in their vacuole in crystalline shape for fighting against toxic effects of cesium. The metal accumulation in C. alata, C. album and A. chlorostachys increased with the increase in metal concentrations in solution, and the metal accumulation in shoots was always significantly higher than those in roots for all three species
