现行《环境空气质量标准》（GB 3095—2012）的实施，取得了哪些成效？ 生态环境部原总工程师刘炳江：现行《环境空气质量标准》（GB 3095—2012）的实施，有力引领了我 国环境空气质量的显著改善，减轻了空气污染的健康危害。现行标准于2012年发布，首次增加了PM2.5 浓度限值；结合2013年发布的《大气污染防治行动计划》，标志着我国大气污染防治工作进入空气质量 管理的新阶段。2015年—2024年，全国主要环境空气污染物浓度大幅下降。其中，PM2.5年均浓度从46 微克/立方米下降至29.3微克/立方米，降幅达36%；可吸入颗粒物（PM10）、二氧化硫（SO2）、二氧 化氮（NO2）、一氧化碳（CO）浓度降幅均超过25%。其中，SO2年均浓度从23微克/立方米降至8微克/ 立方米，降幅高达65%。截至2024年，全国环境空气质量达标的地级及以上城市数为222个，占全部城 市数的65.5%，创历史新高。同时，"十四五"期间我国克服全球变暖背景下臭氧（O3）本底浓度上升的 不利因素，积极推动前体物减排，协同控制PM2.5和O3污染，遏制了O3浓度增长的趋势。污染物浓度的 持续降低，有效减轻了空气污染对 ...

PM2.5仍然是对人体健康影响最大的大气污染物。 多位专家表示，随着治理不断深入，大气污染特征与实际需求也在发生变化，大气污染防治将步入深度 攻坚和转型升级的新阶段。一方面，产业升级、能源结构调整和绿色交通等综合措施同步推进，对地方 治理能力、技术支撑和精细化管理提出更大挑战；另一方面，跨区域污染传输问题也对区域协作提出更 高要求。中国环境科学研究院研究员褚旸晰表示，新的形势下，仍面临污染天气多发等压力与挑战。 生态环境部上述负责人介绍，此次同步修订的《环境空气质量指数（AQI）技术规定》和《环境空气质 量评价技术规范》是标准实施的配套技术文件，AQI用于向公众及时发布空气质量健康信息，为公众出 行提供健康指引；评价技术规范用于开展环境空气质量达标判定和考核评估，是标准的重要补充。 但这一标准仍有改进空间。这位负责人介绍，从保护健康来看，根据WHO最新研究成果，PM2.5仍然 是对人体健康影响最大的大气污染物。因此，WHO于2021年更新了《全球空气质量指南》，收严了 PM2.5年均浓度指导值。我国有关研究也显示，长期和短期PM2.5污染暴露均对人体健康造成不利影 响。因此，需要通过加严浓度限值更好保护公众健 ...
