Mercury spilled from a mercurial sphygmomanometer on a hot carpet can vaporize and pollute the environment. We observed the vaporization of mercury in model experiments. Mercury (0.15g) was heated on a hot carpet and the near-by air was sampled with a midget impinger. The evaporated mercury levels were 5.0, 6.3, 8.1 and 10.0mg/m(3) at 20, 40, 60 and 80 minutes, respectively at a height of 30cm from carpet. The result indicated that even if a small quantity of mercury remained on the hot carpet, it could evaporate and pollute the indoor air. Little is known about the influence on human health of low mercury exposure, especially on children. In order not to pollute the air, we need to pay attention to mercury.

:从水银血压计溢出的汞在热地毯上会蒸发并污染环境。我们在模型实验中观察到了汞的蒸发。将汞(0.15克)在热地毯上加热,并用小型撞击器取样附近的空气。在距地毯30cm的高度处,分别在20、40、60和80分钟时蒸发的汞含量分别为5.0、6.3、8.1和10.0mg / m(3)。结果表明,即使少量的汞残留在热毯上,也会蒸发并污染室内空气。关于低汞暴露对人类健康的影响知之甚少,尤其是对儿童而言。为了不污染空气,我们需要注意汞。
