Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are found on fly ash and in flue gas of municipal waste incinerators. Municipal waste incinerators seem to be the most important source for PCDDs and PCDFs emitted into the air during the last decades. PCDD/F formation takes place in the cooler zones (250 °C-450 °C) of a municipal waste incinerator, at the electrostatic precipitator. Copper is an important component of the fly ash that can catalyse the formation of PCDDs and PCDFs. Inhibition of the formation can be done by complexation of the metals (Cu) with EDTA or NTA.
多氯代二苯并 - 对 - 二噁英（PCDDs）和多氯代二苯并呋喃（PCDFs）存在于城市垃圾焚烧炉的飞灰和烟道气中。在过去几十年里，城市垃圾焚烧炉似乎是向空气中排放PCDDs和PCDFs的最重要来源。PCDD/F的形成发生在城市垃圾焚烧炉较冷的区域（250℃ - 450℃），即静电除尘器处。铜是飞灰的重要组成成分，它能催化PCDDs和PCDFs的形成。通过金属（铜）与乙二胺四乙酸（EDTA）或氮川三乙酸（NTA）络合可以抑制其形成。
