Rhizosphere characteristics of the arsenic hyperaccumulator Pteris vittata L. and monitoring of phytoremoval efficiency

Popis výsledku v původním jazyce

We investigated changes in the rhizosphere characteristics of Pteris vittata (Chinese Brake fern) relevant for its use in phytoextraction. Despite substantial removal of As by the fern, As was not significantly decreased in the rhizosphere soil solutionafter one croping, apparently due to the large buffer capacity of the soil and possibly because of ion competition with dissolved organic carbon. However, the difference between 0,05 M (NH4)2SO4-extractable labile As in bulk and rhizosphere soil indicated that As was mainly acquired from less available pools. Modeling of the DGT-soil system was able to show that the rate of release from solid phase to solution in the rhizosphere was one-third of that in the bulk soil.
