Abstract
Surface samples were taken from two private residences after real fire accidents. The goal was, to determine the surface contaminations with polycyclic aromatic sulfur heterocycles (PASH), as representatives of a substance class, not investigated in this context, by now, polycyclic aromatic hydrocarbons (PAH) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F). Analytical method for the determination of PASH was developed for the respective matrix. Concentrations measured ranged between 1.70 and 465 μg/m 2 for PASH, 34.3 and 58,800 μg/m 2 for PAH (EPA), and 4.15 and 1,300 ng/m 2 for PCDD/F, as well. Obviously, PASH were formed during the fire accidents. Nevertheless, PAH were the most relevant pollutants after these small fires.
