“…These results indicate that most of the native Zn in the soils studied was occluded by crystalline Fe oxides or held in clay-sized mineral structures. Similar results were also reported by other authors (Shuman 1979(Shuman , 1985Iyengar et al 1981;Neilsen et al 1986;Singh et al 1988), who detected the largest amounts of Zn in the Res-Zn fraction and pointed out that the clay-sized minerals contained most of the Res-Zn.…”

“…Since it is recognized that Fe oxides adsorb considerable quantities of Zn (Shuman 1979(Shuman , 1985Singh et al 1988), heavy application of fertilizers and manures may also result in the gradual incorporation of Zn into the CFeO-Zn fraction. However, long term observation would be required to detect significant changes in the CFeO-Zn fractions.…”

“…Several fractionation schemes for micronutrients availability and fractionation in agricultural soils have been reported in literature (McLaren and Crawford, 1973;Wagemann et al, 1977;Shuman, 1979;Shuman, 1985;Shober et al, 2007). Trace elements fractionations were also studied from environmental perspectives (Filgueiras et al, 2002;Ahdy and Youssef, 2011;Okbah et al, 2011).…”

Thirty seven soil samples were collected from seven agricultural regions in Saudi Arabia to investigate trace element availability and fractionation distribution. Di-ethylene tri-amine penta acetic acid extractable micronutrients ranged from 1.1 to 11.5 µg g -1 for Fe, 0.2-3.7 µg g -1 for Zn, 0.48-13.0 µg g -1 for Mn, and 0.2-3.7 µg g -1 for Cu. Based on published critical levels, Cu was sufficient for most crops in all soils. Four soil samples were low in Mn, 28 were low in Zn, and 31 were low in Fe. Fractionation of micronutrients (Fe, Cu, Zn, and Mn) in selected seven soil samples revealed that the exchangeable fractions were the smallest, with Zn and Cu below detection limits. Carbonate bound fractions showed the micronutrient concentrations in the order Mn>Fe>Cu>Zn. Oxide and hydroxide bound fraction was higher than the previous two fractions; the order of the metals was Fe>Mn>Zn>Cu. For the organic bound fractions, the order was Fe>Mn>Cu>Zn. The residual fraction was the largest. The order of residual micronutrients was Fe>Mn>Zn>Cu. Overall, and considering the total amount of the four micronutrients within each fraction, the five fractions followed the order: Residual> oxide bound>CO3 bound>organic bound>exchangeable. Based on the data, it is recommended that Fe and Zn applications should be included in balanced fertilization programs. Mn and Cu are sufficiently available in the studied soils, and may not need to be supplied to crops

“…A distribuição dos metais nos diversos sítios de adsorção das partículas reativas do solo pode ser usada para estimar a sua biodisponibilidade ou predizer contaminações do ambiente (Bosso & Enzweiler, 2008;Casali et al, 2008). Esse tipo de estudo pode ser realizado com o uso da técnica de extração sequencial, também chamada de fracionamento químico de metais (Shuman, 1979;Sposito et al, 1982;Mattiazzo et al, R. Bras.

A extração sequencial permite obter informações mais detalhadas sobre origem, modo de ocorrência, disponibilidade biológica e físico-química, mobilização e transporte dos metais pesados em ambientes naturais. Com o objetivo de estudar as formas de Pb e Zn foram selecionados oito perfis de solos de diferentes locais dentro de área de mineração e metalurgia de Pb, no município de Adrianópolis (PR), Vale do Rio Ribeira. As amostras foram coletadas nas profundidades de 0 a 10, 10 a 20 e 20 a 40 cm. Foram determinados os teores totais de Pb e Zn e sua especiação nas formas: solúvel; trocável; ligada a carbonatos; ligada à matéria orgânica; ligada aos óxidos de Fe de Al de baixa cristalinidade; ligada aos óxidos de Al cristalinos e filossilicatos 1:1 e 2:1; e residual. Com base nos valores percentuais de participação de cada fração nos teores totais, procedeu-se ao agrupamento das amostras similares por meio da análise de componentes principais (PCA). Houve basicamente duas formas de contaminação dos perfis de solo, sendo uma em decorrência das partículas das chaminés e a outra em função do acúmulo de rejeitos sólidos sobre os solos. A primeira foi mais prejudicial ao ambiente em razão dos maiores teores totais e de formas mais disponíveis no solo (solução mais trocável). De modo geral, houve maior associação de Pb aos carbonatos, seguida das frações residual e óxidos de Fe e Al de baixa cristalinidade. O Zn apresentou-se em formas mais insolúveis, aumentando a participação da fração residual nos teores totais. A PCA foi sensível às diferentes formas de Pb nos solos, pois promoveu o agrupamento das amostras, principalmente, em função da participação das formas trocáveis, ligadas aos óxidos de Fe e Al e ligadas aos carbonatos, em relação aos teores totais.
