“…Even in conditions of HM ion concentration exceeding the toxicity limit miscanthus maintains suffi cient increase of aerial biomass (Arduini et al, 2006a), in subtoxic concentration levels the HM could even promote growth and ion translocation, as demonstrated in experiments with cadmium by Arduini et al (2004). Wanat et al (2013) confi rmed the adaptability of M × g to industrially highly contaminated soils (former settling basins a er shut-down gold mining operation, contaminated with As, Pb and Sb), when plants created rather smaller amount of aerial biomass, but were able to grow on site with no added mineral nutrition. Fernando et al (2004) tested phytoremediation cappacity of M × g to soils contaminated with heavy metals on soils treated with domestic sludge.…”

“…on ash dumps (Técher et al, 2012), or on industrially highly contaminated substrates (Wanat et al, 2013). It is resistant to comparatively high concentrations of HM in soil, which in case infl uence the growth rate and biomass increase, but don't aff ect the rate of metabolic processes in plant (Arduini et al, 2006a, b;Wanat et al, 2013). Even in conditions of HM ion concentration exceeding the toxicity limit miscanthus maintains suffi cient increase of aerial biomass (Arduini et al, 2006a), in subtoxic concentration levels the HM could even promote growth and ion translocation, as demonstrated in experiments with cadmium by Arduini et al (2004).…”

Giant miscanthus (Miscanthus × giganteus Greef et Deu.) is a perennial rhizomatous grass with C4 type photosynthesis, which is distinctive by its resistance to cold temperatures when maintaining a suffi cient photosynthesis rate. We revised potential of Miscanhus for use in soil bioremediation, especially from biological point of view. Translocation rate from roots to aerial part is low in general, but Miscanthus is able to grow even on highly contaminated soils without artifi cial fertilization. We also discussed the role of root exudates in pollutant immobilization, chelation and uptake. Commetabolism of polycyclic aromatic hydrocarbons with assistance of soil microbes shows promising results and signifi cant reduction of tetracyclic PAHs in soil. Miscanthus is therefore suitable for immobilization of inorganic pollutants in soil and removal of organic pollutants, which makes it suitable to create buff er zones for surface waterway protection, stabilization of heavily contaminated substrates (e.g. reclaimed burrows of mining industry and sedimentation pools). According to low content of pollutants in aerial biomass the harvested plant material is deemed safe for further agricultural or industrial use.

Vegetation has successfully been used for cleaning up metal(loid) polluted water bodies and lands through extracting and accumulating of contaminants in their aboveground biomass (phytoextraction). As this remediation technique is approaching extensive demonstration scale application and potential commercialisation, research efforts have been investigating new ways to achieve valorization of its by-products, the heavy-metal-enriched biomass (HMEB). Biomass pyrolysis as an energy conversion technique represents a key step to numerous valorization options of HMEB.During the pyrolysis of HMEB, understanding the thermal decomposition pathways, and the migration and transformation of metal(loid)s are critical for the production of clean, safe and value-added end-products. This work performs a state-of-the-art review of the studies conducted on phytoextraction and biomass pyrolysis of HMEB with emphasis on the properties of pyrolysis products as well as the behavior of heavy metal(loid)s during pyrolysis in relation to HMEB feedstock properties and the variables of the process.
