“…According to Abreu et al (2005), Brazil's soils range for micronutrients is as follows (in mg dm -3 ): B-0.01-10.6; Cu-0.1-56; Mn-1-325; Pb-0.00-63.9 and Zn-1-453, while the respective average values for São Paulo state were: B-0.32; Cu-2.5; Mn-16; Pb-0.85 and Zn-4.8. The higher values would be indicative of anthropogenic inputs, either due to excess application of fertilizers or to industrial or mining activities.…”

Phytoremediation is an attractive option to remove metal from contaminated soil since it is a simple, low-cost, and environmentally friendly procedure. To better examine the phytoremediation potential of kenaf (Hybiscus canabinnus), mustard (Brassica juncea), turnip (Raphunus sativus) and amaranth (Amaranthus crentus) plants, a greenhouse experiment was performed in which these species were grown on a soil contaminated with Zn, Cu, Mn, Pb and B. The translocation, the bioconcentration and the removal index, the transference factor and the time to reach 50% of element removal from soil, among other indicators, were used in order to identify a hyperaccumulator. Kenaf plants were more tolerant to the conditions tested, with the highest dry matter production and no visual toxicity symptoms. Amaranth would be the species chosen to remediate the soil under field conditions as it presented the higher indexes for decontamination of Zn and Mn and was also able to remove B. Turnip showed the best results for Pb removal. All species tested were able to remove B from soil. In spite, none of the plant species tested could be characterized as a hyperaccumulator.

“…Para o Estado de São Paulo, ABREU et al (2005) sugerem os seguintes valores de interpretação para Zn, extraídos com DTPA pH 7,3, em mg dm -3 : baixo (0-0,5), médio (0,6-1,2), alto (1,3-2,3), muito alto (2,4-15), toxidez (>130). Baseando-se nestes valores, 57 % das amostras do horizonte A tiveram valores baixos, 21% dos valores foram considerados médios, 7% altos e 15% muito altos, nas duas classes mais altas a maioria dos solos eram derivados de rochas básicas (Tabela 1).…”

RESUMOEm amostras dos horizontes A e B de vinte e oito perfis de unidades de solos representativas do Estado de São Paulo fez-se a determinação de zinco usando os extratores DTPA pH 7,3 (ZnDTPA); Mehlich-1 (ZnM1); HCl 0,1 mol L -1 (ZnHCl); EDTA (ZnEDTA); e, NH 4 OAc 1 mol L -1 (ZnAc). O teor total de zinco nas amostras de solo estava alto, entretanto, notou-se somente uma pequena fração na forma disponível. O zinco total foi mais influenciado pelo teor de óxido de ferro (r=0,75). Para os teores considerados biodisponíveis, o pH foi o componente mais importante com coeficientes de correlação que variaram de 0,52 (ZnDTPA) a 0,66 (ZnAc). A análise dos componentes principais (PCA) revelou que os dois primeiros componentes principais explicaram 66% da variação, mostrando a associação entre os seguintes atributos dos solos: silte, pH, cálcio, magnésio, valor T, sílica, óxido de ferro, ZnT, ZnDTPA, ZnM1, ZnHCl e ZnEDTA, em que havia valores superiores a 0,63 no F1. No F2 ficou demonstrada a associação entre os teores de argila, areia fina e óxido de alumínio. Foi observada ambiguidade nos F1 e F2 para a areia grossa. Concluiu-se que: a maioria das amostras de solo apresenta potencial para o aparecimento de deficiência de zinco em curto e médio prazos e a PCA foi eficiente no agrupamento de solos originários de mesmo material de origem, indicando que as formas de Zn analisadas são influenciadas positivamente pelos teores de silte, Ca, Mg, sílica e Fe 2 O 3, pH e valor T.Palavras-chave: análise de solo, micronutriente, extratores químicos, análise multivariada, componente principal. ABSTRACT TOTAL AND AVAILABLE ZINC IN SOIL PROFILES FROM SÃO PAULO STATE, BRAZILTotal and available zinc were analized in samples of A and/or B horizons of twenty eight representative soil profiles of the State of São Paulo, Brazil. Amounts of Zn extracted by DTPA pH 7.3 (Zn DTPA), Mehlich-1 (Zn M1), HCl 0.1 mol.L -1 (Zn HCl), EDTA (Zn-EDTA), and NH 4 OAc(Zn Ac) were assessed. Amounts of total Zn (Zn T) in all samples was high, but just a small fraction of it is available. Total Zn correlated well with iron oxide content (r = 0.75). In terms of bioavailable amounts the pH was the most important component, showing correlation coefficients varying from 0.52 for Zn DTPA to 0.66 for Zn Ac. The two first axes of Principal Component Analysis (PCA) explained 66% of the variation, and showed association among the following soil attributes: silt, pH, calcium, magnesium, CEC-value, silica, iron oxides, T-ZN, DTPA-Zn, M1-Zn, HCL-Zn and EDTA-Zn, that presented correlation values higher values than 0.63 with the main axis (FL). The second axis (F2) showed an association among clay content, fine sand, and aluminum oxide. An ambiguity was clear in F1 and F2 to coarse sand. It is concluded that: most samples have potential to show up zinc deficiency in the short and medium term; PCA was efficient in grouping soils from the same parent material, indicating that the Zn analyzed in this study is positively influenced by the silt, Ca, Mg, silica, and iron oxide c...

“…According to Abreu et al [28], the available micronutrients in Brazil's soils fall into the following ranges (in mg dm −3 ): B-0.01-10.6; Cu-0.1-56; Mn-1-325; Pb-0.00-63.9; and Zn-1-453, while the respective average values for São Paulo State were B-0.32; Cu-2.5; Mn-16; Pb-0.85; and Zn-4.8. Higher values are indicative of anthropogenic inputs, either due to excessive application of fertilizers or urban and industrial wastes resulting from industrial or mining activities.…”

The aim of this work was to characterize the main inorganic contaminants and evaluate the effect of lime addition, combined with soil dilution with uncontaminated soil, as a strategy for mitigation of these contaminants present in a soil polluted with auto scrap. The experiment was performed in a greenhouse at Campinas (São Paulo State, Brazil) in plastic pots (3 dm−3). Five soil mixtures, obtained by mixing an uncontaminated soil sample with contaminated soil (0, 25, 50, 75, and 100% contaminated soil), were evaluated for soil fertility, availability of inorganic contaminants, and corn development. In addition to the expected changes in soil chemistry due to the addition of lime, only the availability of Fe and Mn in the soil mixtures was affected, while the available contents of Cu, Zn, Cd, Cr, Ni, and Pb increased to some extent in the soil mixtures with higher proportion of contaminated soil. Liming of 10 t ha−1followed by soil dilution at any proportion studied was not successful for mitigation of the inorganic contaminants to a desired level of soil fertility, as demonstrated by the available amounts extracted by the DTPA method (Zn, Pb, Cu, Ni, Cr, Cd) and hot water (B) still present in the soil. This fact was also proved by the phytotoxicity observed and caused by high amounts of B and Zn accumulating in the plant tissue.
