Potential of Forage Grasses in Phytoremediation of Lead through Production of Phytoliths in Contaminated Soils

Phytoremediation has become a promising technique for cleaning Pb-contaminated soils. Grasses have phytoextractor potential extracting metal from soil by transporting it and accumulating in high concentrations their shoots, they the ability to immobilize inactivate via phytoliths. The objective of this work was evaluate phytoremediation forage grasses through production phytoliths occlusion Pb cultivated Three greenhouse experiments were conducted completely randomized design, separated type (Typical Hapludox, Xanthic Hapludox Rhodic Hapludox), 3 × 4 factorial scheme consisting three (Megathyrsus maximus, Urochloa brizantha decumbens) four rates (0, 45, 90 270 mg kg−1) with repetitions. influenced increases higher availability Typic Quartzipsamment promoted toxicity, as indicated reduced dry weights increased phytolith shoots grasses. capture soils related genetic physiological differences most tolerant excess Pb, phytoliths, making grass that can be used future
