Stable cesium (Cs-133) uptake by Calla palustris from different substrates

Popis výsledku v původním jazyce

The uptake of stable cesium (133Cs) by Calla palustris was evaluated from four different substrates: water, soil, keramzit (a clay granule) and water with the addition of a potassium compound, after an eight days exposure to a solution of 0,5 mM cesium chloride. Stable cesium was used because it is commonly supposed that its uptake by plants is the same of that of radiocesium (137Cs). The plants were differentiated in their parts (roots, healthy leaves, dead leaves and flowers) and analyzed with ICP-MS. The lowest average concentration of absorbed Cs was found in plants exposed in soil (0,7 mg/kg, S.D. = 96,8), while the highest in plants exposed in water (147 mg/kg, S.D. = 51,7). During the experiment the water planted plants removed 31,6% of provided Cs while those planted in soil removed only 0,06%. The addition of potassium to water was tested because of the competition effect that arises between these two elements: this effect was confirmed with the result that the average uptake in the presence
