“…A novel application of hemp-based materials for the sequestration of metals Liquid/solid adsorption is one of the most frequently used techniques for the decontamination of aqueous media worldwide (Berefield et al 1982;McKay and Al Duri 1989;Volesky 1990;McKay 1996;Wase and Forster 1997;Cooney 1999;Ho et al 2002;Crini and Badot 2010). Adsorption is a physical-chemical method of separation in which substances present in a liquid become bound to the surface of a solid material (Treybal 1987;Tien 1994;Volesky 1990Volesky , 2004McKay 1996;Yang 2003). It is a process of partition of the molecule to be eliminated, called the adsorbate, between the aqueous solution and the solid, named the adsorbent or biosorbent/sorbent, depending on the type of material used.…”

et al.. Hempbased adsorbents for sequestration of metals: a review. AbstractWith the increasing focus on renewable materials and sustainability issues, the development of non-conventional materials from natural resources and possessing complexing properties is currently an area of extensive research due to their potential applications in biosorption processes for pollutant removal. Among them, the hemp plant (Cannabis sativa), an annual high yielding industrial crop grown for its fibres and seeds, is one of the most promising materials for biosorption of metal ions from diluted waste streams. In this review, an extensive list of hemp-based biosorbent literature has been compiled and discussed. After a brief description of hemp and its properties and applications, the review gives a general overview of liquid-solid biosorption processes for metal sequestration from aqueous solutions onto hemp-based materials.

“…Hemp could be grown on soils contaminated with metals or radioactive elements. Hemp plants were shown to be effective in cleaning the soil around the site of Russia's Chernobyl nuclear disaster (Vandenhove and Van Hees 2003). Recently, they were considered for use near Fukushima.…”

“…Specifically, hemp plants involved in phytomanagement strategies can profitably produce fibres that could be commercialised as insulating or composite material, cellulose materials from stem (suitable for packaging industry), and seeds representing a source of oil for biofuel production. The hemp potential for phytotechnologies has been poorly explored so far; most studies have focused on tolerance and accumulation of metals [13][14][15][16][17] and few reports deal with plant behaviour versus organic contaminants such as chrysene and benzopyrene [18] and radio-compounds [19]. Therefore, a better characterisation of the growth and physiological responses of hemp plants in metal-contaminated soil under controlled conditions is requested.…”

Hemp is a promising plant for phytomanagement. The possibility to couple soil restoration to industrial crop cultivation makes this plant attractive for the management of contaminated sites. In this trial, Cannabis sativa L. plants were grown in a greenhouse on soils from two sites of “Valle del Sacco” (Lazio Region, Italy), a wide area contaminated by agro-industrial activities. One site was representative of moderate and diffuse metal(loid) multi-contamination, above the Italian concentration limit for agriculture (MC—moderately contaminated). The second site showed a metal(loid) content below the aforementioned limit, as a typical background level of the district (C—control). After 90 days, biometric and physiological parameters revealed satisfactory growth in both soil types. MC-grown plants showed a slight, but significant reduction in leaf area, root, and leaf biomass compared with C-grown plants. Chlorophyll content and chlorophyll fluorescence parameters, namely the quantum yield of primary photochemistry (Fv/Fm) and the Performance Index (PIABS), confirmed the good physiological status of plants in both soils. Metal(loid) analyses revealed that As, V, and Pb accumulated only in the roots with significant differences in MC- and C-grown plants, while Zn was found in all organs. Overall, preliminary results showed a satisfactorily growth coupled with the restriction of toxic metal translocation in MC-grown hemp plants, opening perspectives for the phytomanagement of moderately contaminated areas.
