摘要
Mobility of heavy metals has been investigated in sewage sludge as well as in ashes obtained by incineration of this sludge at the temperature range of 850-1000 degrees C. In the ashes, heavy metals created the most durable connections with immobile fractions which did not have a major significance in a toxicological aspect. A clear influence of temperature on the forms of occurrence of heavy metals in fractions has not been proved. In the range of applied incineration temperatures, only the mobilities of copper and zinc increased with the increase of incineration temperature.
