补充资料: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。
