“…In general, concentration of heavy metals in maize plants was not affected by increasing rates of biosolids. Oliveira et al (2002) showed that Cd, Cr, Ni and Pb concentrations in sugarcane leaves, stalks and juice were also below the detection limit of the methodology used, and that Cu and Zn contents in plants were not affected by successive waste compost applications. Melo et al (2002) and Anjos & Mattiazzo (2000) corroborate those findings.…”

“…Entretanto, para predizer a fitodisponibilidade e, ou, a mobilidade de metais pesados em solos, outros extratores devem ser testados (McBride, 1995). Os extratores mais empregados para avaliar os teores disponíveis de metais pesados às plantas em áreas que receberam resíduos que contêm metais, como o lodo de esgoto, são as soluções ácidas, como a de HCl 0,1 mol L -1 , de Mehlich-1 e Mehlich-3, e o agente complexante DTPA (Anjos & Mattiazzo, 2001;Abreu et al, 2002).…”

“…A solução com DTPA é utilizada para extrair, predominantemente, as formas lábeis de metais pesados (Abreu et al, 2002), sendo adotada como método oficial dos laboratórios de análise de solo do Estado de São Paulo. É usada para extrair teores disponíveis de Fe, Cu, Mn e Zn de solos, por apresentar boas correlações com os teores destes metais nos tecidos de diversas culturas agrícolas .…”

“…The organic matter that most stood out for this characteristic was the urban waste compost, with 0.78 g, more than 100% higher than the treatment without organic matter. Oliveira et al (2002) pointed out that application of urban waste compost to cultivated soils has the capacity to increase the phytoavailability of the nutrients P, K, Ca and Mg, as well as increase the pH and CEC, together with the reduction Means followed by different letters in the column are significantly different by the Scott-Knott's test at 1% probability level. OM: Overall mean; SFM: shoot fresh mass; RFM: root fresh mass; SDM: shoot dry mass; RDM: root dry mass; TFM: Total fresh mass; and TDM: total dry mass.…”
