| Abstract:
The effect of main soil properties and different content of As and Cd in soil on their accumulation by four species of vegetables and their distribution into main parts of plants was investigated in a model pot experiment. Three soils, unpolluted Fluvisol, Luvisol with elevated content of As and Chernozems with high content of Cd were used for determination of soil property effects on element accumulation by vegetables. Unpolluted Chernozems was used for determination of distribution of both elements in main plant parts. Radish, carrot, spinach and green beans represented different species of vegetables. Highest content of As was accumulated in plants grown in Luvisols, lower in Fluvisols and the lowest in Chernozems. High As availability at Fluvisols led to higher plant element accumulation than in Chernozems. Highest As accumulation was found in roots of spinach, mainly in secondary roots. The rest of crops accumulated also higher portion of As in roots than in above ground plants, only green beans showed better As mobility and accumulated more than half of the element in leaves and shoots. The highest Cd content was always found in plants grown on contaminated Chernozems soil. Among all crops the highest accumulation was found by leaves and by roots of spinach. Lower accumulation showed radish and carrot and the lowest one green beans. High Cd mobility was confirmed by its accumulation in leaves of vegetables. All plants accumulated more than half Cd in leaves, only Cd accumulation by above ground biomass of green beans was low and caused less than 13 % of the whole uptake. | |
