我国环境监测总站：北方多地受沙尘影响污染局势难以有用缓解

我国环境监测总站对沙尘回流痛经怎么办缓解疼痛方式进行研判剖析。今天（16日）白日西北和华北大部区域受弱偏南风影响，强沙尘气候形成的污染带持续在甘肃、宁夏、陕西、山西、河南、河北中南部和山东中西部等地停留，一起受沙尘回流影响，污染带规模逐步向北延伸，受影响区域PM10浓度保持重度至严峻污染，特别甘肃、宁夏和陕西中北部一带PM10浓度居高不下，甘肃多个城市站点PM10浓度保持在3000—4000微克/立方米以上。14时至15时前后，北京逐步遭到沙尘回流影响，自西南向东北方向监测站点PM10浓度值顺次敏捷上升，到18时，北京六个区PM10小时浓度监测值已到达重度污染水平（遍及挨近或超越400微克/立方米）。

我国环境监测总站猜测，今天夜间至明日白日，北方区域全体受偏东和偏南风影响，沙尘停留和回流局势难以得到有用缓解，受沙尘影响的重度或以上污染带估计向西、向北推移。华北中部处于风场辐合区，污染停留危险较高，北京17日全天估计轻至中度污染，部分时段PM10小时值或许到达重度或以上污染水平。（总台央视记者刘洁）
