摘要：The Lerma river is one of the most polluted water bodies in Mexico, it presents low biodiversity and lets grow up aquatic plants resistant to the pollution. The aim of this work was to evaluate the concentration and bioaccumulation factors (BAF) of Cr, Mn, Fe, Cu, Zn and Pb in aerial and submerged structures of water pennywort (Hydrocotyle ranunculoides) from the upper course of the lerma river (UCLR). Inductively coupled plasma –optical emission spectrometry was used to determine the concentration of heavy metals in water and H. ranunculoides. Results show that the BAF of Fe and Zn were higher than those of Cu, Mn, Cr and Pb; with the exception of Zn, BAF were higher in the submerged structures of the plant, which shows low mobility of analyzed metals. As a result of this study H. ranunculoides can be considere as good indicator of metal pollution in water bodies.
