Data on the interaction of hyperaccumulating plants with nanoscale metals Zn and Cd

The article describes: growth phenotypes of the four plant species (Noccaea caerulescens, Thlaspi perfoliatum, Arabidopsis halleri, Arabidopsis thaliana) before and after the treatment with ionic and nanoscale Zn and Cd (Fig. 1); the method of synthesis and characterization of ZnS QDs and CdS QDs (Fig. 2); the genetic characterization (performed with molecular markers) of the four plant species, their relative genecological relation (Fig. 3); a conceptual workflow designed to detect the amount of ionic Zn and Cd in the original solution/suspension used for the treatment (Fig. 4); the determination of Zn and Cd in the treatment soils after 30 days from supplement of ionic and nanoscale Zn and Cd (Fig. 5); the effect of the treatment on root elongation (Fig. 6); a workflow of a novel analytical method designed to detect the ionic and nanoscale Zn and Cd in the plant tissues after digestion with three different methods (Fig. 7); a reconstruction experiments with an exsiccated powder of plant tissue spiked with the same amount of Zn in the ionic and nanoscale forms (Fig. 8); a TEM-EDX analysis on these powdered plant tissues after removal of all soluble (ionic) Zn to show the presence of Zn in a non soluble form (nanoscale) (Fig. 9); the calculation of Bioconcentration Factor (BCF) and Translocation Factor (TF) and their ratios (Table 1); all data of the "spiking" experiments (Tables 2 and 3).
