吸入汞蒸气发生急性汞中毒,国内自1960年以来,先后有过几次报导~([1,2,3,4]),本文对一建筑施工单位的工人在溜金工作中,因吸入汞蒸气发生急性中毒提出报告。一般情况工艺过程:金片加热(约600℃)后加水银(约1:9)制成糊状的金汞混合物——汞齐。用汞齐涂上铜胚(铜胚先用氰化钾擦洗)→烘焙(约400℃)→磨光。反复几次而成。1960年8月该单位在没有通风防护措施的溜金工作中,20多天共用水银20多公斤。造成8例溜金工人全部急性汞中毒。并在非直接接触工种的41人中,有13人发生汞吸收。
Inhalation of mercury vapor in acute mercury poisoning has been reported several times in China since 1960 ([1,2,3,4]). In this paper, workers in a construction unit are working on the process of taking gold, Vapor acute poisoning report. General process: gold plate heated (about 600 ℃) after the addition of mercury (about 1: 9) made of paste-like mixture of mercury and mercury - amalgams. Coat copper foil with amalgam (copper foil first scrub with potassium cyanide) → baking (about 400 ℃) → polishing. Repeated several times. In August 1960, the unit had more than 20 kilograms of common mercury in more than 20 days in the gold-removing work without ventilation protection measures. Resulting in 8 cases of gold workers all the acute mercury poisoning. Thirteen of the 41 non-direct-working trades were mercury uptake.
