ABSTRACT
In the fresh bottom ash samples from municipal waste incineration plant were determined the basic physico-chemical properties such as: dry mass, pH, pseudo-total content of cadmium, lead and copper. To study fractional composition of investigated heavy metals the BCR method was used (F1- acid soluble and exchangeable fraction, F2- reducible fraction, F3- oxidizable fraction, F4- residual fraction). The average percentage of cadmium in particular fractions was as follows: F1 (37.5%) > F4 (27.2%) > F2 (25.3%) > F3 (10.0%), for lead: F4 (36.5%) > F2(27.2%) > F3(23.4%) > F1(12.9%), and in the case of copper F4(66.3%) > F3(22.1%) > F2(7.4%) > F1(4.2%). Among the studied metals, in mobile pool (F1-F3) the highest amount of cadmium was noted (72.8%); for lead it was 63.5%, and for copper 33.7% of pseudo-total content.
