全国仍有六成城市PM2.5年均浓度高于25微克/立方米，与美丽中国建设目标尚有差距。 生态环境部新发布的《环境空气质量标准》将于3月1日正式实施。这是我国自2012年以来首次全面收紧 国家空气质量标准，细微颗粒（PM2.5）再次成为本次修订的重点关注对象，旨在巩固并扩大近年来空 气质量改善的成果。修订后，PM2.5年均浓度二级限值从35微克/立方米调整为25微克/立方米。 六成城市PM2.5浓度仍超25微克/立方米 据介绍，新标准实施设置五年过渡期，旨在为结构调整和源头减排等根本性治理举措提供充足时间。 空气质量达历史最优 从2013年《大气污染防治行动计划》（"大气十条"）到2018年《打赢蓝天保卫战三年行动计划》，再到 2023年《空气质量持续改善行动计划》，我国大气污染治理政策体系持续深化。通过结构性减排，推动 高耗能、高排放发展模式向绿色、循环、低碳转型，目前已取得阶段性成效。 "新标准设置了五年过渡期，目的是为结构调整、源头减排等治本之策留出足够的缓冲时间和空间。修 订标准体现的是空气质量改善的目标和方向，并不意味着要求各地立即达标。何时达标、如何达标，将 通过科学设定的路径和措施，力求'跳一跳够得 ...

中经记者 封莉 北京报道 2月13日，《中国经营报》记者从上海警方获悉，警方在打击大气污染违法犯罪专项行动中发现，有不 法分子故意篡改扬尘在线监测系统数据。 据了解，为了保护生态环境与空气质量，上海市明确规定在建工程、干散货码头堆场等场所，须委托第 三方企业安装运行扬尘在线监测系统，实时采集上报颗粒物质量浓度数据。一旦数据超标，行政监管部 门将督促整改。然而，部分企业竟故意篡改监测数据以逃避监管。 近日，上海警方全链条查处打击涉及监测设备生产、运维及第三方认证环节的相关违法犯罪行为，共抓 获42名涉案人员，查实涉案监测设备千余台，涉及上海市多处建设工地、码头、堆场及搅拌站。 据警方介绍，自2026年1月以来，上海市公安局环食药侦总队会同市生态环境局研判发现，上海市多家 扬尘在线监测运维企业监测数据异常，涉嫌弄虚作假。警方随即牵头奉贤、杨浦、浦东等属地公安分局 开展核查。 "在研判过程中我们发现，有部分设施运维单位上传的数据远小于我们实际检测的数据，由此发现存在 超标排放未被监管到的情况。"办案民警表示。 经查，犯罪嫌疑人金某等人在经营扬尘在线监测设备运维公司期间，勾结第三方检测认证机构员工姚某 等人，使用虚假 ...

衡量一座城市的"气质"，PM2.5浓度与空气质量优良率是两项硬指标。 2025年1月至11月，浙江省杭州市区交出了一份亮眼"成绩单"：全市PM2.5浓度为27.9微克/立方米，较去 年同期改善2.1%，远优于35微克/立方米的国家标准；空气质量优良天数比例达85.9%，同比上升5个百 分点。 这两项关键指标的显著进步，标志着杭州大气污染治理迈入新阶段。 健全机制 打响精准"科技战" 大气治理是一项复杂的系统工程，杭州为此建立了高位协调、齐抓共管的工作机制。据了解，由分管副 市长每月主持召开的全市空气质量提质进位工作例会，已成为常态化制度。会议不仅系统总结前期工作 成效，更直面问题短板，对治理难点、堵点进行现场点评和协调，有效压实各方责任，推动形成"一盘 棋"治气大格局。 "这种高频次的调度和督导，让各责任单位保持高度警觉，治气的合力空前凝聚。"市生态环境局相关负 责人表示。 杭州的"蓝天保卫战"是一场精准的"科技战"。长期以来，全市以工程减排、结构减排、管理减排为抓 手，排定并实施1029个治气减排项目，从源头深挖潜力，降低本地污染物排放总量。 结构减排是治本之策。杭州聚焦移动源这一污染"大户"，加速推进"两 ...
