Recently, a netizen posted on social media claiming to have stockpiled 100 mercury thermometers, sparking widespread attention and debate. The user explained that, concerned about electronic thermometers running out of battery or malfunctioning—especially amid recurring pandemic waves and extreme weather events—they chose to keep traditional mercury thermometers as an ’emergency backup.’ However, this behavior has raised concerns among health and environmental professionals.While mercury thermometers are known for their accuracy and independence from power sources, they contain toxic mercury. If broken, they can contaminate the environment and pose serious health risks, particularly to children and pregnant women. China began phasing out mercury-containing products in 2017 and will fully ban the production and import of mercury thermometers by 2026, in compliance with the Minamata Convention on Mercury, an international environmental treaty.Experts advise caution when using or storing mercury thermometers at home. If one breaks, proper cleanup procedures must be followed: ventilate the room, avoid direct contact with mercury, collect droplets using stiff paper or cardboard, seal them in a container, and dispose of them safely. Vacuum cleaners or brooms should never be used, as they can spread mercury vapor. Safer alternatives include digital thermometers and infrared forehead thermometers, which are both convenient and non-toxic.Although stockpiling 100 mercury thermometers may stem from a desire to be prepared, it is neither safe nor environmentally responsible. Rational preparedness and scientifically sound practices remain the best approach to handling emergencies.
近日，有网友在社交平台上表示自己囤积了100支水银温度计，引发广泛关注和讨论。该网友称，由于担心电子体温计电池耗尽或出现故障，在疫情反复和极端天气频发的背景下，选择储备传统水银温度计作为‘应急备用’。然而，这一行为也引发了专业人士的担忧。水银温度计虽然测量精准、无需电源，但其内部含有有毒的汞元素。一旦破碎，不仅会造成环境污染，还可能对人体健康构成威胁，尤其是对儿童和孕妇。中国自2017年起已逐步限制含汞产品的生产和销售，并于2026年前全面禁止水银温度计的生产与进口，以履行《水俣公约》的国际环保承诺。专家提醒，家庭应谨慎使用和存放水银温度计，如不慎打碎，需按照规范流程处理：开窗通风、避免直接接触、用硬纸板收集汞珠并密封丢弃，切勿用吸尘器或扫帚清理。更安全的替代品包括电子体温计、红外额温枪等，它们不仅便捷，且无毒无害。囤积百支水银温度计虽出于未雨绸缪的考虑，但从安全与环保角度出发，并不值得提倡。理性储备、科学防护，才是应对突发情况的正确方式。
