In the present study, seven heavy metals, i.e., Cr, Cd, Fe, Mn, Cu, Pb and Mg were used for estimation of heavy metal pollution and the bioconcentration and translocation factors corresponding to the plant Eichhornia crassipes in Deepor Beel, Assam, India. Sediment and water hyacinth (Eichhornia crassipes) samples were collected from three different zones of the wetland; zone I is proximate to the Boragaon landfill region, zone II is the central portion of the wetland and zone III constitutes the site in the industrial zone. It was observed that the heavy metal concentrations in the sediment column of the wetland are significantly higher compared to the water hyacinths. Furthermore, in the water hyacinth samples collected from the three zones, it was observed that the heavy metal concentrations were significantly higher in the roots as compared to the shoots. This indicated an insignificant translocation of heavy metals from the roots to the shoots, as a result of which, all the heavy metals are concentrated in the roots. This was verified by the translocation factor, whose values were found to be minimal and inconsequential. Also, the bioconcentration factor of the water hyacinth samples was estimated and found to be higher in the central and industrial region, which suggests that the metal availability was very low in the landfill region, despite having considerably higher concentrations of heavy metals in the sediments. The findings of the study would prove to be consequential in determining the adverse effects of eutrophication and heavy metal contamination in the wetland, which would thereby aid in undertaking necessary steps in curbing the pollution levels.
