Resumo: Although sewage sludge (biosolid) provides nutrients for plant growth, its successive use may result in the accumulation of heavy metals to levels detrimental to the environment. Pb behaviour in red nitosol with twice-treated contaminated sewage sludge at interval of 18 months was analysed. Soil samples received five different treatments: one with biosolid without Pb (control); two with biosolid with Pb in concentration 2,500; 5,000 µg g-1; two with Pb plus cadmium (Cd) (as interferer) in the same concentration 2,500 + 2,500 and 5,000 + 5,000 µg g-1, respectively. Pots containing the treated soil were cultivated with maize in a green house for 75 days. Pb was extracted by nitric perchloric digestion and analyzed by atomic absorption spectrometry. Soil samples with sewage sludge and contaminated by Pb presented a higher concentration of lead at 0-20 cm deep. Metal concentration remained constant in all treatments at 20-60 cm deep. Low absorption of Pb by plants was detected

Neste intuito, foi estudado o destino do Pb em um Nitossolo Vermelho, tratado duas vezes com biossólido contaminado, num intervalo de 18 meses. Amostras do solo de 0-80 cm de profundidade foram colocadas em sua posição natural em vasos de PVC. Os solos de 0-20 cm de profundidade de cada tubo receberam cinco tratamentos: um com biossólido sem Pb (controle); dois com biossólido com Pb na concentração 2.500; 5.000 µg g-1; dois, com a mistura de Pb mais cádmio, Cd (interferente) na mesma concentração 2.500 + 2.500 e 5.000 + 5.000 µg g-1; respectivamente. As amostras de solo tratado foram recolocadas nos respectivos vasos e o experimento, com três repetições, foi desenvolvido em casa de vegetação utilizando o milho como planta teste. Após 75 dias do plantio, foram feitas as coletas das plantas e dos solos. Depois da preparação das amostras e respectivas digestões com solução nitro-perclórica, a concentração de Pb foi determinada pela espectrometria de absorção atômica. As amostras de solo de 0-20 cm, tratadas com biossólido contaminado, apresentaram as maiores concentrações de Pb. A concentração do metal permaneceu constante ao longo do restante da coluna de solo (20-80 cm). A concentração de Pb extraída pelas plantas permaneceu abaixo dos níveis fitotóxicosUniversidade Estadual De Maringá2008-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/275510.4025/actascitechnol.v23i0.2755Acta Scientiarum.
