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.
水银从一个汞柱式血压计洒落在温暖的地毯上，会蒸发并污染环境。我们在模型实验中观察了汞的蒸发情况。将0.15克汞放在温暖的地毯上加热，并用小型冲击式气体采样器对附近空气进行采样。在距离地毯30厘米的高度处，20、40、60和80分钟时汞的蒸发水平分别为5.0、6.3、8.1和10.0毫克/立方米。结果表明，即使少量汞残留在温暖的地毯上，也会蒸发并污染室内空气。关于低汞暴露对人体健康的影响，尤其是对儿童的影响，人们知之甚少。为了不污染空气，我们需要关注汞。
