“…This could result from changes in soil pH. Sulfur decreases soil pH and increases the solubility, availability and mobility of heavy metals (Tichý et al 1997, Seidel et al 1998, Kayser et al 2000, Martinez et al 2000 al. 2004).…”

“…Soil organic matter and pH are the key factors affecting the content and mobility of heavy metals in soil (Soliman et al 1992, Martinez and Motto 2000, Borůvka and Drábek 2004, Šichorová et al 2004. Another important consideration is human activity which contributes to soil contamination in some regions of Poland, thus leading to changes in the natural heavy metals content.…”

A three-year field experiment was conducted in North-East Poland. Each year three sulfur fertilization rates in the form of sulphate (S-SO 4 2-) and pure (S-S 0 ) sulfur were applied: 40, 80, and 120 kg/ha. After the third year of the study, the application of sulfate and elemental sulfur decreased the zinc content of 0-40 and 40-80 cm soil layers, as compared with soil sampled before the experiment. Over the entire experimental period, sulfur fertilization had no significant effect on changes in the natural copper content of soil at a depth of 0-40 and 40-80 cm. Manganese concentrations remained at a similar level at a soil depth of 0-40 cm. The manganese content of the 40-80 cm soil layer was substantially lower than in the 0-40 cm horizon. An insignificant increase in the lead content of soil was observed. The applied doses of sulfate and elemental sulfur led to an increase in the cadmium content of soil depth of 0-40 cm. Sulfur fertilization contributed to a decrease in the nickel content of soil. The applied doses of sulfate and elemental sulfur exerted a stronger effect in the 0-40 cm soil layer than in the 40-80 cm horizon. Ke y word s: fertilizer; S-SO 4

“…Kaya et al (2009) reported that the application of sulfur and sulfur-containing waste resulted in decrease in soil pH, but it also increased the concentrations of nutrients available to plants, such as Zn, Cu and Mn. Sulphur decreased soil pH and increases EC of soil, availability and mobility of heavy metals (Martinez andMotto, 2000 andCui et al, 2004).…”

“…An acid extractant, such as Mehlich-I, often extracts greater amounts of heavy metals than DTPA and NH 4 OAc (Martínez & Motto, 2000). The proportions of total Zn, Cd, Ni, and Cu extracted with Mehlich-I were of 37, 33, 6, and 10%, respectively, of the total contents extracted by the USEPA 3052 method.…”

Few investigations have been carried out about the comparison of desorption rate and amount of heavy metals extracted successively by organic acid mixtures mimicking the rhizosphere and routine extractants in sewage sludge-amended soils. Extractions of Zn, Cd, Ni, Cr, and Cu were performed in samples of a sewage sludge-amended soil using seven extractants: four organic acid mixtures and three routine extractants (DTPA, Mehlich-I, and ammonium acetate). Results from single pass extractions, in which the extractable metal contents were determined by simply extracting the soil a single time, as well as from 15 successive extractions, in which the solid residues of the first extraction was successively extracted 14 additional times, of heavy metals were analyzed. The extractability of heavy metals in a single pass extraction was, in general, as follows: Mehlich-I > DTPA > organic acids > NH 4 OAc. The highest rates of extraction followed the general order: DTPA > Mehlich-I > organic acids > NH 4 OAc. While Mehlich-I presented the highest extractability of heavy metals among studied extractants, DTPA showed a high extractability of Zn, Cd, Ni, and Cu in a single extraction as well as the highest rates of extraction among the studied extractants. The transfer of heavy metals from soil to organic acid solutions is slower than to DTPA and Mehlich-I extractants.

Extrações de Zn, Cd, Ni, Cr e Cu foram realizadas em amostras de um solo de carga variável tratado com lodo de esgoto usando-se sete extratores: quatro misturas com ácidos orgânicos e três extratores usados na rotina (DTPA, Mehlich-I e acetato de amônio). Os resultados para uma única extração, em que o conteúdo de metais extraíveis foi determinado simplesmente extraindo-os do solo uma única vez, bem como após 15 extrações sucessivas, em que o resíduo sólido da primeira extração foi extraído sucessivamente por mais 14 vezes, foram analisados. A extractabilidade dos metais em uma extração simples foi, em geral, como segue: Mehlich-I > DTPA > ácidos orgânicos > NH 4 OAc. As mais elevadas taxas de extração seguiram a ordem: DTPA > Mehlich-I > ácidos orgânicos > NH 4 OAc. A maior extração de metais foi obtida com Mehlich-I, enquanto, o DTPA também extraiu alta quantidade de Zn, Cd, Ni e Cu em uma extração simples, bem como obteve as mais altas taxas de extração entre os extratores estudados. A transferência de metais do solo para as soluções de ácidos orgânicos foi mais lenta que para os extratores DTPA e Mehlich-I. Palavras-chave: Latossolo, taxa de extração, elementos-traço
