This research aimed to characterize the chemical composition in the Euterpe oleracea seedlings (upper parts) and in mature trees. The phytoextraction potential the seedlings were determined through method X-ray fluorescence analysis. The Al concentration in the seedlings upper parts was four times higher than preconized as a hyper accumulator species. We also found high concentrations of Fe and Si. The Cu and Ca was lower considered a normal level for the seedlings, but Ca, which may represent an antagonism effect caused by the strong presence of Al and Fe. These results highlight the phytoremediation potential for Al, Fe and maybe Cu. The Si reduces the phytotoxic effects and contributed to enhance the Al and Fe absorption and translocation processes to the upper plant parts. The fast uptake and translocation to the seedlings upper parts highlight the potential to use this species in phytoextraction of potential toxic elements from the soil.
