本品的主要作用是麻醉和神经毒性。对其它器官的损害虽属可能,但少见得多。代谢主要侵入途径是吸入,各家报告肺内潴留平均自36～74%不等。经皮吸收仅属次要。体内的三氯乙烯有10～20%不变地呼出。两种主要代谢物(三氯乙醇和三氯乙酸)的排泄占三氯乙烯吸收量的80～90%。三氯乙醇大部分在24小时内排出。每天连续接触则排泄逐日略增,约3天趋于稳 The main role of this product is anesthesia and neurotoxicity. Damage to other organs is possible, but much less common. Metabolism is the main route of entry is inhaled, each reported average retention of lung within 36 ~ 74%. Transdermal absorption is only secondary. Trichlorethylene in the body 10 ~ 20% unchanged exhaled. Excretion of the two main metabolites (trichloroethanol and trichloroacetic acid) accounted for 80-90% of the total trichlorethylene absorption. Trichloroethanol most of the discharge within 24 hours. Continuous exposure to daily excretion slightly increased day by day, about 3 days tends to be stable
