多氯二苯并二噁英类分子式：CAS号：性质：(1)多氯二苯并二噁英类(polychlorinated dibenzo-p-dioxins；PCDD)的简称。又称二苯基二噁英(diphenylene dioxins)。中间环5、10两位置为氧原子，其余1～4，6～9各位置可被卤素原子或有机基团取代。被氯原子取代时，随氯原子数(1～8个)的多少，可形成8个同系物，75个异构体(同族体)。性质稳定，不易分解。其毒性与氯原子取代的位置密切相关，有4个氯原子的二噁英是有毒的(共22个)，其中四氯二苯并二噁英(TCDD)毒性最强。二噁英的前驱物是氯联苯、氯苯、氯苯酚等含氯芳香烃化合物，在燃烧过程中形成二噁英。它在自然界能天然生成，人为来源主要是废弃物的焚烧排放物，如城市垃圾、工业废物、医院废物、防腐剂处理过的木材、有机制品、电容器和绝缘器中绝缘液、旧轮胎作能源等的焚烧；工业生产的排放源有造纸厂漂白废液、生产氯的石墨电极渣、催化剂高温氯化活化、钢铁冶炼和废金属回收等。在环境中的分布，地表土中含量最多，植物和河湖沉积物中其次，大气飞灰和地表水中较少。动物实验证实二噁英有致癌致畸作用，列为人类可疑致癌物，其毒性危害程度远超过有机氯农药和多氯联苯。(2)特指四氯二苯异二噁英。
