多氯二苯并噻吩（PCDTs）是多氯二苯并呋喃（PCDFs）的含硫类似物。可能的多氯二苯并对二恶英同系物的总数为135种，从一氯化合物到八氯化合物。环境中多氯二苯并对二恶英的来源并不确切。在纸浆和造纸厂的废水、废物燃烧和金属回收产生的烟道气和飞灰、工业设施附近的沉积物以及底栖水生生物中均发现了多氯二苯并对二恶英。多氯二苯并对二恶英也在多氯联苯的焚化过程中形成。多氯二苯并对二恶英的形成过程可能与多氯二苯并呋喃的形成过程类似。
Polychlorinated dibenzothiophenes (PCDTs) are sulfur‐containing analogues of polychlorinated dibenzofurans (PCDFs). The total number of possible PCDT congeners is 135, from monoto the octachlorinated compounds. The origin of PCDTs in environment is not exactly known. PCDTs have been found in pulp and paper mill effluents, in stack gas and fly ash from waste combustion and from metal reclamation, in sediments near industrial facilities and in benthic aquatic organisms. PCDTs are formed also in the incineration of PCBs. Probably, PCDTs are formed by chemical processes similar to those of the formation of PCDFs.
