“…Napiergrass (Pennisetum purpureum Schum) produces the greatest shoot-mass of all herbaceous plants [5], and it has a relatively high 137 Cs removal ratio (CR) among species studied for phytoremediation [10,11]. In a previous field study, a maximum CR of 0.57% was achieved in napiergrass planted at high density on soils contaminated with high levels of 137 Cs (3404 kBq m −2 ) [12].…”

Napiergrass is fast-growing perennial known for its high potential for accumulation of cesium (Cs). Cs is highly mobile within a plant and can be distributed to various plant organs. Here, we investigated the distribution of cesium-133 (133 Cs) and competitively translocated cationic minerals, such as potassium (K), calcium (Ca), and magnesium (Mg), in different organs of napiergrass. Treatments comprised four concentrations of 133 Cs applied to soil: 0 (as control); 300; 500; and 1000 μM. Leaf blades contained significantly higher concentrations of 133 Cs than stems under 300 and 500 μM 133 Cs treatments (P < 0.01). Specifically, significantly greater 133 Cs content was measured in younger parts of stems and leaf blades compared with mature or older plant parts.

“…As reported by Ishii et al (2015), P. purpureum can withstand several highly contaminated conditions. Liu et al (2009) and Kang et al (2012) also demonstrated that P. purpureum is resistant to media that are contaminated with heavy metals, including soil with a high copper level in a pot trial and in solutions containing stable caesium. This thus indicates that P. purpureum could be an ideal phytoremediator.…”

“…Other than constructed wetlands, hydroponic systems can also be applied to treat wastewater. Hydroponically grown P. purpureum has been reported to produce a large biomass and accumulate high concentrations of caesium in the aerial parts (Kang et al, 2012;Gupta and Walther, 2017). Besides, P. purpureum can also be applied in situ by directly transplanting it on the contaminated soil.…”

Organic and/or heavy metal pollutants in soil and wastewater can be remediated by phytoremediation. Phytoremediation combines the disciplines of plant physiology, soil microbiology and soil chemistry. There are several ways by which plants extract, stabilize, filtrate, volatilize or degrade the contaminants. However, the effectiveness of phytoremediation relies upon the type of plant used. Pennisetum purpureum, commonly referred to as Napier grass, is one of the exceptional phytoremediators due to its rapid growth rate and ability to survive in highly contaminated soils. In the present review, the potential use and applicability of P. purpureum to remediate various contaminated areas was highlighted and comprehensively discussed, especially the five phytoremediation mechanisms involved (i.e., phytodegradation, phytoextraction, phytofiltration, phytostabilization, phytovolatilization). The application and management of P. purpureum in soil and wastewater phytoremediation were also critically presented. The coupling of phytoremediation and bioenergy is the zero-waste concept that can be applied since P. purpureum contains high lignocellulosic content that can be utilized as carbon source for biofuel production, such as ethanol and butanol.

“…Reports showed that red root pigweed (Amaranthus retroflexus) is a good accumulator of 137 Cs with higher uptake rate and plant growth, as also shown during the phytoremediation practices for Cs-contaminated soil in the vicinity of Chernobyl, Ukraine (Lasat et al 1997(Lasat et al , 1998Dushenkov et al 1999). Kang et al (2012) showed that napier grass (Pennisetum purpureum Schum.) under hydroponic condition is also a good accumulator of Cs and may be applied for phytoremediation.…”

Application of radioactive elements or radionuclides for anthropogenic use is a widespread phenomenon nowadays. Radionuclides undergo radioactive decays releasing ionizing radiation like gamma ray(s) and/or alpha or beta particles that can displace electrons in the living matter (like in DNA) and disturb its function. Radionuclides are highly hazardous pollutants of considerable impact on the environment, food chain and human health. Cleaning up of the contaminated environment through plants is a promising technology where the rhizosphere may play an important role. Plants belonging to the families of Brassicaceae, Papilionaceae, Caryophyllaceae, Poaceae, and Asteraceae are most important in this respect and offer the largest potential for heavy metal phytoremediation. Plants like Lactuca sativa L., Silybum marianum Gaertn., Centaurea cyanus L., Carthamus tinctorius L., Helianthus annuus and H. tuberosus are also important plants for heavy metal phytoremediation. However, transfer factors (TF) of radionuclide from soil/water to plant ([Radionuclide]plant/[Radionuclide]soil) vary widely in different plants. Rhizosphere, rhizobacteria and varied metal transporters like NRAMP, ZIP families CDF, ATPases (HMAs) family like P1B-ATPases, are involved in the radio-phytoremediation processes. This review will discuss recent advancements and potential application of plants for radionuclide removal from the environment.
