ResumoNeste trabalho de pesquisa foram avaliadas a capacidade do capim braquiária (Braquiária Decumbens) e mostarda da índia (Brassica Juncea) de extrairem metais de solo L 25, Latossolo Roxo. O delineamento experimental foi realizado em blocos com esquema fatorial 2 espécies x 4 doses de metais x 4 repetições. As doses de metais foram baseadas nos valores de Intervenção para solos agrícolas da decisão no 195-2005-E, de 23/11/2005 da CETESB, aplicadas na forma de sais com as seguintes concentrações em mg kg-1: dose zero; dose I -adição combinada de 450 de Zn, 3 de Cd, 180 de Pb, 70 de Ni e 150 de Cr; dose II -2 vezes a dose I e dose III-3 vezes a dose I. A colheita foi realizada após 180 dias do plantio. A mostarda da índia adaptou-se a todas as concentrações aplicadas. O zinco foi o metal que apresentou maior remoção do solo contaminado pelas duas espécies. Para contaminação dose I a mostarda da índia se mostrou melhor na remoção de cromo (37%), chumbo (39%) e níquel (68%), enquanto o capim braquiária removeu melhor os metais chumbo (40%), cromo (62%) e níquel (88%). Ambas espécies revelaram ser boas opções para fitorremediação de solos contaminados com metais pesados. Palavras-chave:Fitoextração, Brassica Juncea, Brachiaria Decumbens, Poluição Do Solo. AbstractWe evaluated the ability of pasture grass and Indian mustard plants grown in eight-liter pots to extract metals from the soil latosol. The experimental design consisted in randomized blocks with factorial 2 species x 4 metal doses x 4 replications. The metal doses were based on values recommended by the CETESB interventional decision number 195-2005-E issued on 23rd November 2005 and were applied in the form of inorganic salts with the following concentrations in mg kg-1: dose zero -without addition of any metal; dose I -combined addition of 450 Zn, 3 Cd, 180 Pb, 70 Ni, and 150 Cr; dose IIcombined addition of 900 Zn, 6 Cd, 360 Pb, 140 Ni, and 300 Cr; dose III-combined addition of 1350 Zn, 9 Cd, 540 Pb, 210 Ni, and 450 Cr. The crop was harvested 180 days after planting. Brassica juncea was the species that best adapted to all the applied concentrations. Zinc was the element that showed greatest soil removal in soil contaminated by both species. For the contamination dose I Brassica juncea was the best for chromium (37%), lead (39%), and nickel (68%) removal, while Brachiaria decumbens removed the metals lead (40%), chromium (62%), and nickel (88%) the most effectively. Both species were excellent choices for the phytoremediation of soils contaminated with heavy metals. Key
