Cu、Ni、Pb and Cd showed more affinity to the oxidizable metal fraction. Bio-availability of all the measured metals, except Cd,decreased with the increase in composting time. Therefore, we conclude that composting could stabilize the heavy metals present in the sludge and decrease the risk of soil pollution.

污泥堆肥中Cu、Ni、Cd、Cr主要以残渣态形式存在，Cu、Ni、Pb、Cd四种重金属元素的可氧化态含量也相对较高，除Cd外，经过堆肥化处理后所有重金属的有效态含量均呈下降趋势，因此，堆肥可以促进污泥中的重金属稳定化，降低土壤的污染风险。
