Opis:: In the fresh samples of municipal solid waste incineration (MSWI) bottom ash, the fractional composition of Zn, Cr and Co was investigated. The BCR method was utilised to evaluate the acid soluble and exchangeable fraction (F1), reducible fraction (F2), oxidizable fraction (F3) and residual fraction (F4). Physico-chemical parameters such as pH, dry mass, and pseudo-total metal content were also determined. The percentage of zinc in fractions was in the following order: F3 (31.8%) > F1 (30.6%) > F2 (27.8%) > F4 (9.8%), for chromium F4 (88.7%) > F3 (5.4%) > F1 (3.2%) > F2 (2.7%), and in the case of cobalt F4 (59.8%) > F1 (14.3%) > F2 (13.6%) > F3 (12.3%). Mobile metal pool (F1–F3) gathered the most of zinc (90.2%) and the least of chromium (11.3%).

Opis:: The basic physicochemical properties such as: dry mass, pH, pseudo-total content of cadmium, lead and copper, were determined in the fresh bottom ash samples from a municipal waste incineration plant. In order to study fractional composition of the 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 the pseudo-total content.
