二噁英通常指具有相似結構和理化特性的一組多氯取代的平面芳烴類化合物,屬氯代含氧三環(huán)芳烴類化合物,包括75 種多氯代二苯并一對一二噁英和135種多氯代二苯并呋哺,縮寫為PCDD/Fs。研究最為充分的有毒二噁英為2 位、3位、7 位、8 位被氯原子取代的17 種同系物異構體單體(congenor),其中,2,3,7,8-四氯二苯并-對-二噁英(2,3,7,8一TCDD)是目前所有已知化合物中毒性最強的二噁英單體( 經(jīng)口LDSO按體重計僅為1pug/kg),且還有極強的致癌性( 致大鼠肝癌劑量按體重計10μg/g)和極低劑量的環(huán)境內(nèi)分泌干擾作用在內(nèi)的多種毒性作用。這類物質(zhì)既非人為生產(chǎn)、又無任何用途,而是燃燒和各種工業(yè)生產(chǎn)的副產(chǎn)物。
