Mercury thermometers were once widely used due to their high accuracy, but their core component—elemental mercury—is highly toxic and poses serious risks to human health and the environment. If a thermometer breaks, mercury vapor quickly evaporates into the air; inhalation can damage the nervous system, kidneys, and lungs, with children and pregnant women being especially vulnerable. Moreover, improperly disposed mercury thermometers can leach mercury into soil and water, where it bioaccumulates through the food chain, ultimately endangering human health.To address this global environmental and health hazard, the Minamata Convention on Mercury was adopted in 2013. As a signatory, China has committed to phasing out mercury-containing products. Starting in 2026, the country will fully ban the production of mercury thermometers and sphygmomanometers. This move not only reduces sources of mercury pollution but also accelerates the shift toward safer, eco-friendly alternatives like digital thermometers. Modern digital thermometers are non-toxic, user-friendly, faster, and increasingly accurate—meeting both everyday and clinical needs effectively.The comprehensive ban on mercury thermometer production reflects China’s commitment to green development, fulfills its international environmental obligations, and safeguards public health and the well-being of future generations.
水银体温计因其高精度曾被广泛使用，但其核心成分——金属汞（水银）具有高度毒性，对人体健康和生态环境构成严重威胁。一旦体温计破裂，汞蒸气会迅速挥发到空气中，吸入后可能损害神经系统、肾脏及肺部，尤其对儿童和孕妇危害更大。此外，废弃的水银体温计若未被妥善处理，其中的汞会渗入土壤和水源，通过食物链富集，最终危害人类健康。为应对这一全球性环境与健康风险，2013年《水俣公约》正式通过，中国作为缔约国之一，承诺逐步淘汰含汞产品。自2026年起，我国将全面禁止生产含汞体温计和血压计。此举不仅有助于减少汞污染源，也推动医疗设备向更安全、环保的电子体温计等替代品转型。电子体温计不仅无毒、易用，且测量速度更快、精度不断提高，已能充分满足日常和临床需求。全面禁产水银体温计，是践行绿色发展理念、履行国际环保责任的重要举措，更是对公众健康和子孙后代生存环境的有力保障。
