Abstract

The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in EUCALYPTUS grandis and AILANTHUS altissima plants. For doing so, EUCALYPTUS and AILANTHUS trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, with the majority of trees being AILANTHUS and EUCALYPTUS. Amounts of Cd, Pb, Zn, Cu, and Mn have initially been at toxic levels which declined after cultivation. Fibrous clay minerals have been added to soils as a natural adsorbent to adsorb heavy METALS like Pb, Cd, Zn, and Mn. Accumulation of the elements in the roots and shoots has been in the following order: Cu>Zn>Mn>Cd>Pb>Fe. The organ metal concentrations have not statistically translocated from roots to shoots of plants, except for Zn and Cu whose concentrations have been significantly higher in roots. EUCALYPTUS is well capable of extracting elements from contaminated soils, compared to AILANTHUS, particularly in case of Cu and Cd. The percentage of mycorrhizal colonization proves to be more in pots with AILANTHUS plants grown in contaminated soil, suggesting enhanced effect of high metal concentrations on plant infection by G. mosseae. AMF assists soil remediation by enhancing the growth and retention of toxic elements by AILANTHUS, while no substantial change has been observed between inoculated and non-inoculated EUCALYPTUS plants by AFM, regarding translocation of elements to plants. The possibility of increasing metal accumulation in roots is interesting for PHYTOREMEDIATION purposes, since most high-producing biomass plants, such as EUCALYPTUS, retain heavy METALS in roots.
