2024年1月，河北省沧州市发布重污染天气红色预警，这是当地空气污染应急响应体系中的最高级别预警。根据沧州市生态环境局通报，受不利气象条件和区域传输影响，预计未来数日细颗粒物（PM2.5）浓度将持续升高，空气质量指数（AQI）可能达到或超过300，属于严重污染级别。为应对此次污染过程，沧州已启动Ⅰ级应急响应措施，包括工业企业限产停产、建筑工地全面停工、机动车单双号限行、中小学及幼儿园停课等。政府呼吁市民尽量减少外出，特别是儿童、老年人及患有呼吸系统疾病的人群应避免户外活动，并建议使用空气净化设备。此次红色预警体现了地方政府对公众健康的高度负责，也反映出京津冀及周边地区冬季大气污染防治形势依然严峻。专家提醒，除短期应急措施外，还需持续推进能源结构优化、工业绿色转型和区域联防联控，从根本上改善空气质量。
In January 2024, Cangzhou City in Hebei Province issued a red alert for severe air pollution—the highest level in its air quality emergency response system. According to the Cangzhou Municipal Ecology and Environment Bureau, unfavorable meteorological conditions combined with regional pollutant transport are expected to cause sustained increases in fine particulate matter (PM2.5) concentrations over the coming days, potentially pushing the Air Quality Index (AQI) above 300, which constitutes a ‘hazardous’ pollution level. In response, the city has activated Level I emergency measures, including production cuts or shutdowns at industrial facilities, complete suspension of construction activities, odd-even vehicle restrictions, and school closures for kindergartens and primary/secondary schools. Authorities urge residents to minimize outdoor exposure—especially children, the elderly, and individuals with respiratory conditions—and recommend using indoor air purifiers. This red alert underscores the local government’s commitment to public health and highlights the persistent challenges of winter air pollution in the Beijing-Tianjin-Hebei region and surrounding areas. Experts emphasize that beyond short-term emergency actions, long-term solutions such as energy structure optimization, green industrial transformation, and enhanced regional coordination are essential to achieve lasting air quality improvements.
