The Use of Sorghum in a Phytoattenuation Strategy: A Field Experiment on a TE-Contaminated Site

Phytoattenuation combines phytoextraction or phytostabilization with the economic valorization of biomass produced on contaminated soil. Sorghum bicolor is a suitable crop for this strategy, as it known to be metal-tolerant and can used biogas bioethanol production in strategies toward biofortification. In current investigation, two cultivars, Biomass 133 Trudan Headless (HL), were studied metal-contaminated (Cd, Pb, Zn) field site located northern France assess their potential use phytoattenuation strategy. The yield metal transfer monitored three plots different pollution levels. Both cultivars tolerant high levels conditions, yields similar that obtained uncontaminated sites. Neither changed mobility soil both exhibited metal-excluder behavior. Nevertheless, Cd concentration aboveground part HL, lesser extent, could restrict some options. However, was possible biomass, indicating anaerobic digestion route sorghum grown
