摘要

This work evaluated the potential of Catharanthus roseus in phytoremediation of As, Ba, Cd, Cu, Cr, Ni, Pb, Se and Zn in sewage sludge-based substrates. C. roseus was cultivated for 108days in a treatment containing sewage sludge:vermiculite (70:30%) and in the control with 100% commercial substrate. The plants cultivated in sludge showed approximately four times greater height, number of leaves and stem diameter, as well as 89% higher fresh mass than those of the control. The highest concentrations of the metals were obtained in the roots of plants grown in the sludge, and ranged from 2.04 (Cd) to 1121mg kg(-1) (Zn). Cu, Cd and Zn had a higher bioconcentration factor than 1 in both treatments. On the other hand, the translocation factor value in the control was greater than 1 for Ba, Cd, Cu, Ni, Se and Zn. The results showed that C. roseus was efficient in the phytoremediation of the evaluated metals, in which the translocation process was progressive in the treatment that presented higher metal content.
