Resumo: 	Phytoremediation is an attractive option to remove metal from contaminated soil since it is a simple, low-cost, and environmentally friendly procedure. To better examine the phytoremediation potential of kenaf (Hybiscus canabinnus), mustard (Brassica juncea), turnip (Raphunus sativus) and amaranth (Amaranthus crentus) plants, a greenhouse experiment was performed in which these species were grown on a soil contaminated with Zn, Cu, Mn, Pb and B. The translocation, the bioconcentration and the removal index, the transference factor and the time to reach 50% of element removal from soil, among other indicators, were used in order to identify a hyperaccumulator. Kenaf plants were more tolerant to the conditions tested, with the highest dry matter production and no visual toxicity symptoms. Amaranth would be the species chosen to remediate the soil under field conditions as it presented the higher indexes for decontamination of Zn and Mn and was also able to remove B. Turnip showed the best results for Pb removal. All species tested were able to remove B from soil. In spite, none of the plant species tested could be characterized as a hyperaccumulator.
