摘要
荧光灯管中含有汞,灯管破碎后汞蒸气溢出会对人体健康和环境产生危害。模拟荧光灯管在室内打碎的情形,在打碎后的不同时间段、距离碎灯处不同距离及开窗通风后测定室内空气中汞蒸气浓度,以分析在室内荧光灯摔碎后,汞蒸气散发情况、可能造成的环境污染和对人体健康的危害程度。测试研究结果表明,灯管破碎时,灯管中的汞蒸气只会在灯管打碎瞬间才有可能超过标准警戒水平,并且会在1 min^2 min迅速散发浓度降低至安全水平,只要处理方法合适,不会对使用者和周围环境造成影响。
Fluorescent tube contains mercury, and mercury vapor will overflow from broken tube, which will cause harm to human health and the environment. This paper simulated broken situation of fluorescent tube in indoors, tested mercury vapor concentration in indoor air in different time period, different distances from broken lamp site and ventilation after breaking to analyze emission situation of mercury vapor, possible environmental pollution and harm degree to human health after the breaking the indoor fluorescent lamp. The test results indicated that mercury vapor in tubes is likely to exceed standard alert level in broken moment, and is more quickly to reduce to safe levels in 1 min - 2 min. If the treatment is well done, it. will not affect the user and the surrounding environment.
