【 摘 要 】

Three ash samples from an incinerator in BeloHorizonte (Brazil) were physically and chemically characterized. The chemicalcomposition of the ashes was not always the same, neither in terms of the chemicalspecies nor in terms of the quantities of those that are common to the threeashes. The ashes called CF1 and CF3D contain heavy metals above the detectionlimits of the analytical methods and the zinc concentration is high enough tojustify treatment of the ashes. For these ashes, a high loss on ignition wasfound, indicating that the process of incineration might present failures.
