Core Viewpoint - The production ban on mercury thermometers and related mercury-containing medical devices will take effect on January 1, 2026, leading to a shift in consumer preferences towards alternative thermometer options [1][2]. Group 1: Market Situation - As of January 4, 2026, local pharmacies in Jinan are experiencing a limited supply of mercury thermometers, with prices slightly increasing but not significantly [1]. - Various types of thermometers are available, including electronic thermometers priced between 22.2 yuan and 48 yuan, and a popular non-mercury glass thermometer priced at 19.8 yuan, which is gaining traction among consumers [1][2]. - The most common mercury thermometer has recently faced stock shortages, with only a few remaining in local pharmacies [1]. Group 2: Consumer Preferences - Many consumers, like Ms. Zhang, express skepticism about the accuracy of electronic thermometers, leading to a preference for mercury thermometers, although they are now sold out [2]. - Healthcare professionals, such as nurses, indicate that both ear thermometers and mercury thermometers are still in use, with no clear directive to eliminate mercury thermometers entirely [2]. - The recommendation for consumers is to choose thermometers based on their specific needs, with mercury thermometers suggested for accuracy in safe environments, while electronic thermometers are recommended for convenience, especially in households with children or elderly individuals [2].

Core Viewpoint - The National Medical Products Administration of China has announced a ban on the production of mercury thermometers and sphygmomanometers starting January 1, 2026, due to the toxicity and non-degradability of mercury [1]. Group 1: Reasons for the Ban - Mercury thermometers contain approximately 1 gram of mercury, which can significantly increase the mercury concentration in a room if broken [1]. - Inhalation of mercury vapor can cause symptoms such as dizziness, headaches, and fatigue, with long-term exposure potentially leading to irreversible damage to the nervous system and kidneys, especially in children and pregnant women [1]. - The ban aligns with China's commitment to the Minamata Convention on Mercury, aiming to reduce environmental hazards associated with mercury [1]. Group 2: Handling Broken Thermometers - If a mercury thermometer is broken, it is crucial to ventilate the area immediately and avoid using a broom or vacuum cleaner to clean up the mercury [1]. - The correct procedure involves wearing gloves, using hard paper or tape to collect mercury beads, and sealing them in a container marked as "waste mercury" for proper disposal [1]. Group 3: Alternatives to Mercury Thermometers - For general household use, medical-grade electronic thermometers are recommended for their simplicity and cost-effectiveness [2]. - For infants or uncooperative children, ear thermometers are preferred due to their speed and accuracy in measuring core body temperature [2]. - For those accustomed to the "shake" method, non-mercury thermometers made from gallium-indium-tin alloy are available, which are safe and environmentally friendly [2]. Group 4: Best Practices for Thermometer Use - It is essential to choose thermometers from reputable brands and ensure they have medical device certification [3]. - Regular calibration of electronic thermometers is advised to maintain measurement accuracy [3]. - Proper disposal of any unused or broken mercury thermometers is necessary to ensure health and environmental safety [3].
