Phytoremedial Potential ofTypha latifolia,Eichornia crassipesandMonochoria hastatafound in Contaminated Water Bodies Across Ranchi City (India)

Abstract

Phytoremediation is an emerging technology that uses green plants (living machines) for removal of contaminants of concern (COC). These plant species have the potential to remove the COC, thereby restoring the original condition of soil or water environment. The present study focuses on assessing the heavy metals (COC) present in the contaminated water bodies of Ranchi city, Jharkhand, India. Phytoremedial potential of three plant species: Typha latifolia, Eichornia crassipes and Monochoria hastata were assessed in the present study. Heterogenous accumulation of metals was found in the three plant species. It was observed that the ratio of heavy metal concentration was different in different parts, i.e., shoots and roots. Positive results were also obtained for translocation factor of all species with minimum of 0.10 and maximum of 1. It was found experimentally that M. hastata has the maximum BFC for root as 4.32 and shoot as 2.70 (for Manganese). For T. latifolia, BCF of maximum was observed for root (163.5) and respective shoot 86.46 (for Iron), followed by 7.3 and 5.8 for root and shoot (for Manganese) respectively. E. crassipes was found to possess a maximum BCF of 278.6 (for Manganese and 151 (for Iron) and shoot as 142 (for Manganese) and 36.13 (for Iron).

Removal of Pb, Cu, Cd, and Zn Present in Aqueous Solution Using Coupled Electrocoagulation-Phytoremediation Treatment

“…The bioaccumulation of the metals in the roots was greater than those observed in the aerial parts, except for Pb (Figure 8), as follows: Pb > Cu > Cd > Zn, behavior probably due to a passive adsorption process and metal accumulation in the rhizosphere, as reported by Chandra and Yadav [65] and Hazra et al [66].…”

Phytoremediation potential of Bacopa monnieri in the removal of heavy metals

“…Results indicate that the root parts of the plant possess high concentration of metal ions which indicates a higher accumulation of ions to protect photosynthetic tissue in the above ground parts (Saha, Banerjee and Sarkar, 2015;Salama, Al Watban and Al-Fughom, 2011). High concentration of metal ions in the root indicates that element compartmentalization, tolerance strategy by the plant in respect to the different metal ions and the level of concentration (Hazra et al, 2015;Zengin and Munzuroglu, 2005). This tolerance strategy is common in wetland plants and helps the plant to protect photosynthetic tissues in the above ground parts from the harmful effects of toxic metal ions (Wang et al, 2002;Akinbile, 2016;Mustapha, 2018).…”

Accumulation of Heavy Metal Ions by Eichhornia Crassipes from Battery Industry Effluent under the Influence of Cattle Manure

“…Maximum BCF values for Ar, Pb, Ca, Fe and Zn in E. Crassipes roots were 1.21, 0.37, 1.00, 0.54 and 0.65 respectively; while their maximum BCF values in shoots were 0.69, 0.27, 0.61, 0.27 and 0.40 respectively. In this experiment, aquatic plant had the ability to concentrate various metal ions to its tissues and acts as very good accumulator [23][24][25][26].…”
