Occurrence Handle1:CAS:528:DC%2BD3sXntVOqtr8%3DĪrticleTitleEDTA and HEDTA effects on Cd, Cr, and Ni uptake by Helianthus annuus Occurrence Handle1:CAS:528:DyaK2sXhtVyktbk%3DĪrticleTitleTrace element speciation in selected smelter-contaminated soils in Anaconda and Deer Lodge Valley, Montana, USA Knowing the metal partitioning and mobility of heavy metals it is very important for evaluating the phytoremediation efficiency.ĪrticleTitleCharacterization of pollution at heavy metal contaminated sites: a proposal The same pattern was observed in alkaline soils, where almost 80% of the metals could be remobilized and be potentially available to plants. In acidic soils the content of metals in ready mobile form (exchangeable-bound to carbonates as well as to Fe and Mn oxides) and bound to organic matter constitutes an important source of potentially available elements. In the sequential extraction procedure, considering the total partition, there was a large proportion of Pb, Cd and Zn extracted in a readily mobile form. Results showed that there was a low proportion of immediately soluble metals, as well as a high proportion of metals that could be released and would so be available for plant uptake. Metal mobility and the fractionation of elements and thus the biological uptake of Zn, Pb and Cd by plants were investigated using a simplified analytical procedure for soluble and bioavailable metals using a four-step sequential extraction procedure.
