In recent years, mercury thermometers—once sold for just a few yuan—have seen their prices surge to 20–30 yuan, drawing public attention. Known for their accuracy, simplicity, and lack of reliance on batteries, mercury thermometers have long been widely used. However, with the rise of digital and infrared thermometers, they have gradually faded from mainstream use. More significantly, due to the toxicity of mercury, broken thermometers can pose environmental and health hazards. China began phasing out mercury-containing medical devices in 2017 and plans to fully ban them by 2026.As supply dwindles, some consumers—concerned about the reliability of electronic alternatives or their dependence on batteries—still prefer traditional mercury thermometers. Demand spikes during health crises like the pandemic have further strained availability. This imbalance between supply and demand, coupled with opportunistic hoarding and price gouging by certain sellers, has driven prices up sharply. Weak oversight on some e-commerce platforms has also enabled such profiteering.Experts caution that while mercury thermometers are accurate, they carry safety risks. They recommend using certified, safer digital alternatives. If mercury thermometers must be used, they should be handled carefully to avoid breakage and disposed of as hazardous waste. Rational consumption and science-based health practices are key to ensuring both personal well-being and environmental safety.
近年来，几块钱一支的水银体温计价格被炒至二三十元，引发公众关注。水银体温计因其测量精准、无需电池、结构简单等优点，长期以来被广泛使用。然而，随着电子体温计和红外测温设备的普及，水银体温计逐渐退出主流市场。更重要的是，由于水银具有毒性，若体温计破损可能造成环境污染和健康风险，我国自2017年起已逐步限制含汞医疗器械的生产与销售，并计划在2026年前全面禁止。在此背景下，市面上水银体温计供应日益减少，而部分消费者出于对电子设备不准或电池依赖的担忧，仍偏好传统水银体温计，尤其在疫情等特殊时期需求激增。供需失衡加上个别商家囤货炒作，导致原本仅售几元的产品价格飙升至二三十元。此外，一些平台监管不严，也让高价转卖行为有机可乘。专家提醒，水银体温计虽准确，但存在安全隐患，建议公众优先选择合规、安全的电子体温计。若必须使用水银体温计，应妥善保管，避免摔碎，并按有害垃圾规范处理。理性消费、科学防疫，才能真正保障健康与环境安全。
