Paper Title:
Bioaccumulation of Metals in Different Parts of Weed Species at Proposed Bauxite Mines
  Abstract

We investigated and evaluated metal up-take in three common dominant plants namely Ageratina adenophora, Eupatorium odoratum and Phoenix acaulis from three proposed bauxite mine sites in Araku valley, Vishakhapatnam, India. The concentrations of Cr, Cu, Pb and Zn varied from 14.41 to 87.73 mg/kg, 3.39 to 25.09 mg/kg, 2.48 to 17.39 mg/kg and 5.77 to 50.81 mg/kg, respectively. The variables studied showed significant spatial heterogeneity (General Linear Model, ANOVA, P < 0.05) among sites and metals. Transportation index (Ti) for Zn was >1 for all the species. The pH seemed to have the greatest effect on the solubility / retention of metals in soils thus, enhancing accumulation of metals.
