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.
本文给出了波兰18家医院垃圾焚烧炉燃烧气体和底灰中多氯二苯并二恶英（PCDDs）和多氯二苯并呋喃（PCDFs）的测定结果。其中13家被调查工厂建于1994年至1997年之间。其中8家工厂烟囱气体中的PCDDs/Fs浓度较低，低于0.1 ng-TEQ/m³。有两家工厂烟囱气体中PCDDs/Fs的浓度高于20 ng-TEQ/m³。从热解室采集的所有底灰样本中，PCDDs和PCDFs的含量为8-45微克TEQ/千克。文中描述了所采用的采样和分析方法。
