O método empregado apresentou-se adequado com limite de detecção e desvio padrão aceitável para a determinação de metais em amostras de sedimentos. Cd foi o metal com maior percentagem na fração extraível. Ni e Pb estão presentes principalmente nas frações oxidável e redutível. Cr, Cu e Zn foram encontrados predominantemente na fração residual. A ordem de mobilidade dos metais extraídos foi Pb > Cd > Ni > Cu > Cr > Zn. De acordo com o código de avaliação de risco (RAC), as amostras de sedimentos mostraram risco baixo a médio para todos os metais analisados.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-21T10:10:38Z No. of bitstreams: 1 v22n5a04.pdf: 874335 bytes, checksum: be46552e7376ee70d03b1ad4caa6ed1a (MD5)Made available in DSpace on 2011-12-21T10:10:38Z (GMT).
