“…For determination of metal (Cd, Pb, and Zn) pseudototal concentrations, acid digestion of soil samples was performed using a digestion plate (HotBlock (TM) Environmental Express, USA). The aqua regia solution (HCl + HNO 3 , 3:1, 6 mL) was added and the aliquot heated at 95°C for 75 min ( Nsanganwimana et al, 2015). The accuracy and precision of the metal determination were verified by using a certified reference material (CRM‐141R, Belgium).…”

The energy crop Miscanthus presents high potentials for phytomanagement. Its shoot yield and nutrient accumulation has been extensively characterized in uncontaminated agricultural soils, while very little is known for metal‐contaminated conditions. This study aimed at assessing potential differences in dry matter and metal and nutrient accumulation of the standing aerial biomass in Miscanthus (M. × giganteus) growing in situ on agricultural plots presenting different soil Cd, Pb, and Zn concentrations. Plant samplings were conducted monthly along the growing period from May to December. Cadmium, Pb, Zn, and the concentrations of the nutrients N, P, K, Ca, Mg, and Na were determined in leaves and stems separately. During the growing phase, the maximum dry matter was reached in early in autumn. Whatever the organ, Cd and Zn concentrations were higher on contaminated than on uncontaminated plots. During summer and autumn, Zn and Pb concentrations were higher in leaves than in stems whereas Cd concentrations did not significantly differ between the organs. Concentrations of N, P, K, and Mg decreased across the study period whereas those of Ca and Na increased. Overall, metal and nutrient concentrations depended on plant organ and its development stage. The dry matter and nutrient accumulation patterns were not different between contaminated and uncontaminated plots. The significance of these findings is discussed in light of best phytomanagement practices and potential uses of Miscanthus biomass.

“…They were then oven‐dried at 40°C until constant weight, and finally ground into fine powder using a knife mill (GM200, Retsch) for leaves and an ultracentrifuge mill (ZM 200, Retsch) for stems. Nitric acid (HNO 3 , 70%) and hydrogen peroxide (H 2 O 2 , 30%) were used for sample digestion ( Nsanganwimana et al, 2015).…”

“…M. x giganteus was introduced in Europe and exhibited good production properties while used at the brownfield sites, former mining sites and contaminated agricultural lands (KAHLE et al, 2001;KOCON and MATYKA, 2012;NSANGANWIMANA et al, 2015;MOSA et al, 2016). This plant is a C-4 perennial grass, has a high biomass productivity accompanied by good water use efficiency and low nutrient demands (PIDLISNYUK et al, 2014a).…”

Abstract:The semi-field research on using second-generation biofuel crop Miscanthus x giganteus for restoration of former military site in Kamenetz-Podilsky, Ukraine was carried out during two vegetation seasons. Despite high metal pollution of soil, in particular, by Fe, Mn, Ti, and Zr, no growth inhibition was observed. The concentrations followed pattern soil > roots > stems > leaves. Accumulation of particular metals in roots was different: Fe, Mn and Ti were accumulated rather palpably after the first vegetation season and less tangible after the second one. Cu, Pb and Zn were less accumulative in both vegetation seasons, and for As and Pb the accumulative concentrations were very small. Accumulations in the aboveground parts of the plant in comparison to roots were significantly lower in case of Fe, Ti, Mn, Cu, Zn, Sr and even statistically comparable to zero in case of As, Pb and Zr. Calculated translocation ratio of metals in the plant's parts preferably indicated lack of metals' hyper accumulation. Generally, no correlations were observed between concentrations of metals in the soil and in the upper plant's parts. The research confirmed the ability of Miscanthus x giganteus to grow on the military soils predominantly contaminated by metals.

“…evaluated the use of Panicum virgatum (switchgrass) and Typha latifolia (cattail) for the phytoremediation of biosolids from an end‐of‐life municipal lagoon containing phosphoprous, nitrogen, cadmium, zinc, copper and chromium . Switchgrass and cattail were both capable of phyto‐extracting nitrogen and phosphorus from the biosolids; however, phyto‐extraction of all metals occurred only to a minimal extent, as these trace elements tend to accumulate in the belowground biomass – phyto‐immobilisation/phyto‐stabilisation . In addition, Jeke et al .…”

“…Nsanganwimana et al . investigated the distribution of cadmium, lead, and zinc within M. × giganteus plants, finding that all three metals were stored preferentially in the roots . Over 40 mg kg −1 (dry matter) of both cadmium and lead were accumulated in the roots, as well as up to 150 mg kg −1 of zinc.…”

Making light work of heavy metal contamination: the potential for coupling bioremediation with bioenergy production

Intense anthropogenic activity continues to expose the natural environment to heavy metal contamination. Whilst a number of physical and chemical solutions for remediation exist, the use of higher plants and algae for clean‐up of contaminated landscapes, termed ‘phytoremediation’ and ‘phycoremediation’, respectively, offer an attractive and sustainable alternative. However, these remediation processes will always lead to a high‐moisture, heavy metal‐contaminated biomass, which must be further processed to partition, or render inert, the metal contaminants. Conversion of this metal‐rich biomass into second‐generation biofuels offers a useful route to subsidise the economics of remediation activities. Here we briefly review the various methods for bioremediation of heavy metals, and discuss the potential to produce bioenergy from these biomass sources. Coupling the bioremediation activity to bioenergy production gives far‐reaching social and economic benefits; however, established processes such as direct combustion and anaerobic digestion risk releasing heavy metals back into the environment. Alternatively, thermochemical conversions such as pyrolysis or hydrothermal liquefaction (HTL) offer significant advantages in terms of the segregation of metals into a relatively inert and compact solid phase while producing a biocrude oil for bioenergy production. In addition, preliminary work suggests that the HTL process can also be used to partition essential macronutrients, such as N, P and K, into an aqueous medium, allowing additional nutrient recycling. © 2019 Society of Chemical Industry
