下月起，全面禁产水银体温计！测量精准，几元就能买1支，电子体温计要几十元……为啥要禁？医生解释

Core Viewpoint - The production of mercury thermometers and blood pressure monitors will be banned starting January 1, 2026, as part of China's commitment to the Minamata Convention on Mercury, which aims to reduce mercury pollution and protect public health and the environment [2][12][15]. Group 1: Product Characteristics - Mercury thermometers are known for their high measurement accuracy, being sensitive to even slight temperature changes, and are relatively inexpensive, typically priced around 10 yuan [2][3][10]. - The common mercury thermometer contains approximately 1 gram of mercury, which poses significant health risks if broken, as it can lead to mercury vapor exposure that exceeds safety limits [8][11]. Group 2: Market Trends - There has been a noticeable shortage of mercury thermometers in the market, with prices ranging from a few yuan to around 10 yuan, while alternative electronic and infrared thermometers are significantly more expensive, costing several tens to hundreds of yuan [6][11]. - The transition away from mercury thermometers is driven by their disadvantages, such as being fragile, requiring longer measurement times, and posing health risks due to mercury exposure [11][12]. Group 3: Regulatory Framework - The ban on mercury thermometers is part of the implementation of the Minamata Convention, which came into effect in China on August 16, 2017, and mandates the prohibition of mercury-containing medical devices starting in 2026 [12][15][16]. - The National Medical Products Administration has outlined that existing mercury thermometer products can continue to be registered until December 31, 2025, after which production will cease entirely [15].
