品名

六氟化碲; Tellurium Hexafluoride; CAS：7783-80-4

理化性质

具有臭味的无色气体。分子式Te-F6。分子量241.61。相对密度4.006(-191℃,固体）。2.499（-10℃,液体）。熔点-39.6℃（-38.7℃升华）。沸点-35.5 ℃。

接触机会

化学品,生产和使用人员及实验室人员。

侵入途径

呼吸道。

毒理学简介

大鼠吸入LCLo: 5 ppm/4H。小鼠吸入LCLo: 5 ppm/1H。

毒性很强。兔、豚鼠、大鼠、小鼠在1、5、10、25、50、100ppm不同的浓度下,接触4小时,动物全部死亡; 在1ppm下1小时,可出现呼吸急促,但无死亡。1ppm,1小时／日,连续5天,未见明显改变。

IDLH: +1 ppm [R5]

临床表现

有报道2例吸入50g气体,其中1例口内有金属味,呼气有蒜臭,并有食欲减退、无力和嗜睡。2天后手、臂、颈部出现红斑及疱疹,指间有蓝黑色斑。2例血、尿、肝及肾功能和X线胸片检查均正常。症状于数周内消退。

美国HSDN引用文献：

*TWO CASES OF EXCESSIVE OCCUPATIONAL EXPOSURE TO TELLURIUM HEXAFLUORIDE ... SINCE BOTH WORKERS WERE ALSO HANDLING VOLATILE LIQ ESTERS, SOME INCR ABSORPTION & DEPOSITION MAY HAVE OCCURRED. SIGNS INCL GARLIC BREATH. UNUSUAL FEATURE ... BLUISH BLACK DISCOLORATION OF WEBS OF FINGERS & STREAKS ON FACE & NECK. NO PERMANENT DAMAGE ... . [R15]

*Target organs: Resp system [R4, 217]

*ON A RELATIVE ACUTE TOXICITY BASIS ... TELLURIUM FLUORIDE WOULD APPEAR TO BE EQUALLY AS TOXIC AS SELENIUM FLUORIDE AT 1/5 THE CONCN. /TELLURIUM FLUORIDE/ [R16, 556]

处理

参见<碲及其化合物>。

美国HSDB引用文献：

*The only treatment to be applied in cases of high urinary tellurium levels is to remove the worker from exposure and wait for the element to be excreted, which may take several months. The routine administration of such compounds as chlorophyll or ascorbic acid should be discouraged as it gives a false sense of security. However, in a man who has been taken away from contamination with a stinking breath, a high dosage of vitamin C might help to reduce his odor. /Tellurium/ [R14]

*There is no specific antidote for poisoning by tellurium compounds. The use of BAL /2,3-dimercaptopropanol/ or ascorbic acid is not recommended. /Tellurium cmpd/ [R8, 546]
