Starting January 1, 2026, China will completely ban the production of mercury-containing thermometers and sphygmomanometers. This move stems from a strong commitment to environmental protection and public health. Mercury is a highly toxic heavy metal; if a mercury thermometer breaks, its vapor can quickly evaporate into the air. Inhalation of mercury vapor may damage the nervous system, kidneys, and fetal development. Moreover, improperly discarded mercury thermometers can leach mercury into soil and water, causing long-term environmental contamination.This ban is part of China’s implementation of the Minamata Convention on Mercury—an international treaty aimed at reducing global mercury use and emissions. As a signatory, China has been progressively phasing out mercury-containing products. Today, alternatives such as digital thermometers and infrared forehead thermometers are widely available, offering reliable accuracy, safety, and environmental friendliness for everyday medical use. Experts recommend that households replace any remaining mercury thermometers and dispose of them properly as hazardous waste to minimize health and environmental risks.
自2026年1月1日起，中国将全面禁止生产含汞的水银体温计和血压计。这一举措源于对环境保护和公众健康的高度重视。水银（即汞）是一种剧毒重金属，一旦体温计破碎，其中的汞蒸气会迅速挥发到空气中，被人体吸入后可能损害神经系统、肾脏及胎儿发育。此外，废弃的水银体温计若未被妥善处理，汞会渗入土壤和水源，造成长期环境污染。该禁令是中国履行《关于汞的水俣公约》的重要行动之一。该国际公约旨在全球范围内减少汞的使用与排放，中国作为缔约国，已逐步淘汰含汞产品。目前，电子体温计、红外额温枪等替代品技术成熟、测量准确且安全环保，完全可满足日常医疗需求。专家建议公众尽快更换家中仍在使用的水银体温计，并按有害垃圾规范处置，以降低健康与环境风险。
