The objective of this work was to evaluate the efficiency of an aquatic macrophyte (Eichornia crassipes) as a bioindicator and as an alternative sorbent for the removal of toxic heavy metals Cd, Pb and Cr from swine biofertilizer. A 2x4 factorial design was used, with the factors represented by plant parts (leaves and roots) and the four treatments. The metal concentrations were determined at the beginning of the experiment and after 30 days. The macrophyte showed good efficiency in the removal of toxic heavy metals from swine biofertilizer. It was observed that its radicular system presented larger amounts of Cd, Pb and Cr than did the leaves. Our results show that Eichornia crassipes could be an alternative treatment for biofertilizer and waste from swine cultureDownloads
