PCDDs and PCDFs concentration in combustion gases and bottom ash from incineration of hospital wastes in Poland.
The result from the determination of polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in combustion gases and bottom ash from eighteen of Polish hospital waste incinerators is presented. Thirteen of the investigated plants were built between 1994 and 1997. Eight of them shown low PCDDs/Fs concentration in stack gases, below 0.1 ng-TEQ/mn3. For two plants concentrations of PCDDs/Fs in stack gas were above 20 ng-TEQ/mn3. In all of the samples of bottom ash taken from pyrolytic chambers, PCDDs and PCDFs were in the level of 8-45 micrograms TEQ/kg. A method used for sampling and analysis is described.
