二噁英通常指具有相似结构和理化特性的一组多氯取代的平面芳烃类化合物,属氯代含氧三环芳烃类化合物,包括75 种多氯代二苯并一对一二噁英和135种多氯代二苯并呋哺,缩写为PCDD/Fs。研究最为充分的有毒二噁英为2 位、3位、7 位、8 位被氯原子取代的17 种同系物异构体单体(congenor),其中,2,3,7,8-四氯二苯并-对-二噁英(2,3,7,8一TCDD)是目前所有已知化合物中毒性最强的二噁英单体( 经口LDSO按体重计仅为1pug/kg),且还有极强的致癌性( 致大鼠肝癌剂量按体重计10μg/g)和极低剂量的环境内分泌干扰作用在内的多种毒性作用。这类物质既非人为生产、又无任何用途,而是燃烧和各种工业生产的副产物。
