Phytoremediation is a promising process of soil decontamination when the plant is used as a mechanism of allocation of the undesirable contaminant agent in the treated system. Samples of Cyperus rotundus collected in a contaminated area with industrial residues were evaluated through optical microscopy and inductively coupled plasma atomic emission spectroscopy (ICP - AES). This work aimed to evaluate the phytoremediator potential and the morphological alterations in young epigeous body of C. rotundus caused by pollutant chemicals in comparison with plants collected in the same soil with no contamination (witness). The observed anatomic alterations compared with the witnesses demonstrated the potential polluting effect of contaminants and also indicated the hyperaccumulating behavior of the analyzed plants.
