摘要: The content of heavy metals is the major limitation to application sewage sludge in soil. However, assessment pollution by total metal determination does not reveal true environmental impact. It necessary apply sequential extraction techniques obtain suitable information about their bioavailability or toxicity. In this paper, from before and after aerobic digestion was applied five WWTPs southern Spain influence treatment concentration metals. percentage each as residual, oxidizable, reducible exchangeable form calculated. For purpose, samples were collected two different points plants, namely, mixture (primary secondary sludge) tank (mixed sludge, MS) digested-dewatered (final FS). Heavy metals, Al, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Ti Zn, extracted following scheme proposed Standards, Measurements Testing Programme European Commission determined inductively-coupled plasma atomic emission spectrometry. measured did exceed limits set out legislation mainly associated with less-available fractions (27-28% oxidizable 44-50% residual metal). Co (64% MS 52% FS samples), Mn (82% 79% FS), Ni (32% 26% FS) Zn (79% 62% present at important percentages available forms. addition, results showed a clear increase proportion (oxidizable
