The article presents the results of preliminary tests obtained from the analysis of ash coming from the combustion of various types of waste in household furnaces. The aim of this work was to examine the infl uence of various types of waste burned in household furnaces on the elemental composition of the generated ash. As part of the research, analyses of ash generated from the incineration of mixed waste, plastics, wood, textiles, rubber waste and paper were made. The content of selected metal ions: Mn, Cu, Mo, Zn, Cd, Tl, Cr, Co, Ni, As, Sn, Sb, Pb, V was determined in the tested samples, according to PN-EN ISO 17294-2: 2016-11 standard. The highest concentrations of zinc were found in the large-sized waste, rubber and textile ash samples and highest concentrations of copper were found in the plastic and paper ash samples. The highest concentrations for elements such as copper, lead, cobalt and chromium were recorded for samples of rubber and large-sized waste containing e.g. varnished furniture boards. The obtained results showed that depending on the waste incinerated, the content of selected metals was signifi cantly diff erent, and the highest concentrations were noted for samples of large-sized waste, waste from segregated plastics and waste from rubbers.
