Abstract: In the study, the variations of heavy metal distributions (of Cu, Mn, Pb, and Zn) during the sewage S]sludge composting process were investigated by sequential extraction procedures. The total content of Cu and Zn ill the composted mixture increased after the composting process, Mn and Zn were mainly found in mobile fractions (exchangeable fraction (H), carbonate fraction (F2), and Fe/Mn oxide fraction (F3)). Cu and Pb were strongly associated with the stable fractions (organic matter/sulfides fraction (F4) and residual fraction (F5)). These five metal fractions were used to calculate the metal mobility (bioavailability) in the sewage sludge and composted mixture. The mobility (bioavailability) of Mn, Pb, and Zn (but not Cu) increased during the composting process. The metal mobility in the composted mixture ranked in the following order: Mn > Zn > Pb > Cu
