汞蒸气Hg气体检测管142S MERCURY VAPOUR 0.1-10mg/m3

简要描述:

汞蒸气Hg气体检测管142S MERCURY VAPOUR 0.1-10mg/m3,汞为银白色的液态金属,常温中即有蒸发。汞中毒(mercurypoisoning)以慢性为多见,主要发生在生产活动中,长期吸入汞蒸气和汞化合物粉尘所致。以精神-神经异常、齿龈炎、震颤为主要症状。大剂量汞蒸气吸入或汞化合物摄入即发生急性汞中毒。对汞过敏者,即使局部涂沫汞油基质制剂,亦可发生中毒。接触汞机会较多的有汞矿开采,汞合金冶炼,金和银提取,汞整流器,以及真空泵、照明灯、仪表、温度计、补牙汞合金、雷汞、颜料、制药
