Beijing suffered blast table pollution weather， has not yet launched the emergency plan

Xinhuanet, Beijing, February 16 (reporters Lu Guoqiang and Ni Yuanjin)-blast table! Blast table! Blast table! In the 3 days since the Lantern Festival, and PM2.5 concentrations in the air of Beijing has maintained a pace. In thick fog and haze, in Shijiazhuang and other places have implemented emergency measures such as vehicle restrictions, closure of Beijing, however, still does not start, motor vehicle stops and other contingency plans.

14th, Beijing air pollution emergency response Headquarters Office release information, affected by adverse weather conditions, less pollutant dispersion, concentrations had reached high levels of pollution, the city started air pollution emergency blue early-warning measures.

Late night with fireworks set off surge, to 14th, Beijing's air quality has reached the critical level, and 21 o'clock, Southeast regional PM2.5 concentrations reached 624 mg/m, urban area of 445 mg/m; on 15th, PM2.5 concentration reached 569 mg/m in Beijing city.

Beijing air pollution emergency response Headquarters Office, 14th, release information, expected on 15th Beijing's air quality is still maintained high levels of pollution levels, the city started air pollution emergency blue early-warning measures. In fact, as of the morning of 16th, air quality level has always been a serious pollution levels in Beijing.

According to the Environmental Protection Department monitors data to 16th, in Beijing city and the Northern Territory site has dropped from 5 o'clock on that day 405 mg/m 139 μg/m3 PM2.5 concentrations decreased significantly.

Netizen "z eat man" said, "for three consecutive days of haze and heavy pollution, nor the wind of the future, in particular want to know tomorrow's holiday. "" Blast form for three consecutive days, said heavy pollution plan?! "" Adorable tiny hidden "asked.

According to Beijing city air heavy pollution emergency plans (pilot) under provides, forecast future continued 3 days alternating appeared heavy degrees pollution or serious pollution, will started warning II level, that orange warning, take "cut-off" "suspension" "parked" "stopped burn" measures; forecast future continued 3 days appeared serious pollution Shi, started warning level that red warning, will increased motor vehicle danshuanghao limited line, and in primary and secondary schools and kindergarten closed, measures.

"For PM2.5 monitoring and forecasting, our reserves and accumulated less compared with the weather forecast, there is a relatively large gap. "Environmentalists have described Mr MA.

Experts point out that air pollution forecasting in practice be difficult.

Institute of atmospheric physics, Chinese Academy of Sciences researcher Wang Yuesi says: "forecasting and warning of a different, now, our model prediction can't keep up, warning of severe haze pollution need to predict on consecutive days, on average, without neither clear. The haze situation in one day is not difficult, and PM2.5 concentrations at which public concern, is the difficulty of forecasting. ”

In addition to difficulties in science, experts also point out that, start the motor stops and other emergency measures to face greater difficulties, requires enormous social costs.

"If someone dares to assume this responsibility. "Wang Yuesi says:" when faced with strong haze pollution during the long, we are scientifically, inadequate management and mental, always prepared. ”

"There is no denying that in mega-cities like Beijing to start limiting contingency measures, such as motor vehicles, great influence on social life, the difficulty is also enormous. Can be based on different levels of alert for more refinement of contingency measures. "Mr MA suggested that the" Government is best able to steer "take emergency measures in the field.

Experts pointed out that the published on heavy pollution weather monitoring, health tips, green tips, as well as various advocates of emission reduction measures, Beijing is doing relatively well, but it should be more proactive.

From a longer-term perspective, core is to identify the sources of pollution air pollution, carried out on the basis of effective governance, change "get rich or die tryin" concept.

People said that environmental protection should start from their own up. "No firing, driving less, first thing you do is fundamental. "One citizen said.

　　新华网北京2月16日电(记者卢国强 倪元锦) 爆表！爆表！爆表！元宵节以来的3天中，北京市空气中PM2.5浓度始终保持着这样的节奏。在浓重的雾霾中，在石家庄等地已实施机动车限行等应急措施时，但北京至今未启动停课、机动车停驶等应急预案。

　　14日8时，北京市空气重污染应急指挥部办公室发布信息，受不利气象条件影响，污染物扩散条件较差，浓度已达到重度污染状态，全市启动空气重污染应急蓝色预警措施。

　　随着元宵夜烟花爆竹燃放量猛增，到14日19时，北京空气质量已经达到严重污染水平，21时，东南部地区PM2.5浓度达到624微克／立方米，城区为445微克／立方米；15日零时，北京城区PM2.5浓度达到569微克／立方米。

　　北京市空气重污染应急指挥部办公室14日20时发布信息，预计15日北京空气质量仍维持重度污染水平，全市启动空气重污染应急蓝色预警措施。事实上，截至16日上午，北京市空气质量级别始终处于严重污染水平。

　　根据环保部门监测数据，到16日14时，北京城区与北部地区的站点已由当日5时的405微克／立方米下降至139微克／立方米，PM2.5浓度显著下降。

　　网民“Z铁男”说：“连续三天都是霾，重污染，未来也没有大风，特别想知道明天是不是应该放假。”“连续三天爆表，说好的重污染预案呢？！”“萌微小藏”问道。

　　根据《北京市空气重污染应急预案(试行)》规定，预测未来持续3天交替出现重度污染或严重污染，将启动预警二级，即橙色预警，采取“停产”“停工”“停放”“停烧”措施；预测未来持续3天出现严重污染时，启动预警一级即红色预警，将增加机动车单双号限行、中小学和幼儿园停课等措施。

　　“对于PM2.5的监测和预测，我们的储备和积累比较少，与天气预报比起来，还是有比较大的差距。”环保人士马军介绍。

　　专家指出，空气污染的预测在实际操作中存在一定的难度。

　　中国科学院大气物理研究所研究员王跃思说：“预测与预警不同，目前我们的模型预报跟不上，霾的重度污染预警需要预测连续几天的平均值，没有发生的事情谁也不清楚。某一天的雾霾状况不难报，而公众关心的PM2.5的浓度究竟达到多少，是预测的难点。”

　　除了科学上的难点，专家也指出，启动机动车停驶等应急措施要面临较大的困难，需要巨大的社会成本。

　　“好像谁也不敢负这个责任。”王跃思认为：“面对长时间的强霾污染过程时，我们在科学上、管理上和心理上总是准备不足。”

　　“不可否认，在北京这样的超大型城市启动限制机动车等应急措施时，对社会生活影响极大，难度也极大。可以根据不同的预警级别采取更细化的应急措施。”马军建议，在“政府最能够掌控”的领域采取应急措施。

　　专家指出，在重污染天气的监测发布、健康提示、绿色出行提示，以及各种减排措施的倡导方面，北京市做得还是比较好的，但应更加主动。

　　从更长远地角度看，治理空气污染核心是识别污染的源头，在此基础上展开长效的治理，改变“要钱不要命”的观念。

　　有市民表示，保护环境应该从自身做起。“不放炮，少开车，自己首先做好才是根本。”一位市民说。
