Abstract:
In this study, water-hyacinth (Eichhornia crassipes) was examined as a potential Cd-remediation method from wastewater. To evaluate the water-hyacinths' Cdremoval potential, water hyacinths and suckers of the same size were planted in twelve plastic pots containing six different freshwaters (FW) to wastewater (WW) ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100). The first six pots contained only WW/FW (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100) denoted as T1, T2, T3, T4 T5 and T6 respectively. In next six pots, 2mg/L Cd was added for each WW/FW, and denoted as by T8, T9, T10, T11, and T12. The highest Cd concentration (0.01625 mg kg-1 dwt) was observed in T11 for Root. The bioaccumulation factor (BAF) was higher (2.4 for T6 & T7) in the root than in the shoot (2.1 in T6 & T7). FW (T1) sediments act as a good sink for Cd in addition to root and shoot, however, less Cd content in sediments at (T12) indicating inhibition of plant growth which restrict Cd bioaccumulation in E. crassipes. Moreover, an underlying mechanism for Cd-remediation has also been proposed. This study found that water hyacinth is a suitable plant for largescale phytoremediation of wastewater that has a lot of heavy metals in it.
