Abstract
The present study was carried to estimate and investigate metal accumulation potential of Ceratophyllum demersum and Hydrilla verticillata in an urban lake (Dal Lake), Kashmir, India. Analyses of water and macrophyte samples were done on a monthly basis from March to August. The results showed that Hydrilla verticillata accumulated maximum concentration of Na, K, Mg, Cu, Zn and Cr (mg/g) compared to Ceratophyllum demersum at all selected sites. Data from this study may provide information on the use of Hydrilla verticillata as a hyper- accumulators to bio-accumulate or bio-stabilize heavy metals and metal ions from the polluted water bodies as its phytoremediation capacity increased from March to June and there after showed decreased values at all the selected sites. In Hydrilla verticillata, the general order of concentrations was K>Na>Mg>Cr>Cu>Zn. Biochemical parameters viz. chlorophyll (a, b), total chlorophyll, carotenoids and free sugar content were found to be highest during the month of June and lowest in March in both the selected plants. The present study highlights the fact that both Hydrilla verticillata and Ceratophyllum demersum absorb nutrients from water which proved them as potential phytoremediants for removing the excess concentration of nutrients and heavy metals from the Dal Lake.
