近年来半导体工业中,经常使用AsH_(?),出现了一些中毒病例。在金属冶炼、熔化、电解等作业工人中,AsH_(?)中毒多见。 AsH_(?)中毒症状与吸人量有关,吸入AsH_(?)250ppm(800mg/m~3)瞬间死亡,吸入25~50 ppm(80~160 mg/m~3)30分钟死亡,吸入10ppm(32 mg/m~3)较长时间死亡。AsH_(?)中毒症状与接触时间长短有关系:通常从接触到发病为2~24小时,吸人A_5H_(?)30分钟出现重症、4~6小时为中等症状、48小时后为轻症。总之接触量越大,症状出现越快越严重,预后也多不良。AsH_(?)中毒对以下各方面可出现影响。
In recent years, the semiconductor industry, the frequent use of AsH_ (?), There have been some cases of poisoning. In metal smelting, melting, electrolysis and other workers in operation, AsH_ (?) Poisoning more common. Symptoms of AsH_ (?) Poisoning are related to the amount of aspiration. Inhalation AsH (?) 250ppm (800mg / m ~ 3) died instantly and 25 ~ 50ppm (80 ~ 160mg / 32 mg / m ~ 3) died longer. AsH_ (?) Poisoning symptoms and the length of contact with the relationship: usually from exposure to incidence of 2 to 24 hours, inhalation A_5H _ (?) 30 minutes of severe symptoms, 4 to 6 hours for the moderate symptoms, 48 hours after the mild. In short the greater the amount of exposure, the more rapid the more serious symptoms, the prognosis is also more bad. AsH_ (?) Poisoning can affect the following aspects.
