The author:(作者)归海一刀published in(发表于) 2014/2/17 8:57:56 Festival in Beijing Environmental Protection Department explanation has not started the red warning
Xinhuanet, Beijing, February 17 (reporters Lu Guoqiang and and Ni Yuanjin)-consecutive heavy pollution weather Beijing these days, some people in the face of heavy haze, why not start the highest levels of air pollution in Beijing red alert? Emergency measures taken by the Government departments? In this connection, the reporter interviewed the environmental protection departments and some academics.
Question: why Beijing has not started "air pollution and a red alert"?
Explanation: Beijing environment authorities said, according to the monitoring data, the night of 14th Fireworks let off peak PM2.5 concentrations exceeding 500 micrograms per cubic meter, because of atmospheric static stability, proliferation of poor conditions, the PM2.5 concentrations declined slowly, and sustained impact on the 15th, to air heavily polluted "blue alert".
14th 8 o'clock and, environmental protection departments in 2013 through Beijing's air pollution contingency plan (trial) provides that twice released the city's launch "early warning measures for air pollution emergency blue" message.
15th afternoon, a Beijing environmental protection monitoring center judge, 16th around noon, the city's air quality will be improved gradually from North to South. Monitoring data confirm the environmental sector, to 16th, PM2.5 concentrations decreased significantly in the northern region in Beijing city.
Thus, in the Beijing air pollution does not become "predicting the future 3 days alternating ' high levels of pollution ' or ' pollution '" Orange alert, "predicting the future 3 days ' pollution, '" the red alert level.
According to the Beijing air pollution emergency plan (for trial implementation), when the Orange warning, take the "cut?off" of "lay-off" and "parking" and "stop burning" mandatory pollution reduction of contingency measures such as deal when the red alert, will also increase the motor vehicle danshuanghao the limit line, the muck, sand and dust, traffic disruptions, measures such as primary and secondary schools and kindergartens were closed.
Question two: haze, what emergency measures taken by the Government?
Explanation: the Beijing air pollution emergency plan (trial) provides that while the blue alert level, reminders for health protection should be disseminated to the public health measures, and promoting conscious proposed pollution reduction measures to reduce pollutant emissions.
Beijing Environmental Protection Department said air pollution after the blue alert level is reached, via text messaging, micro-blogging, micro-, Internet, car TV blue alert has been issued to the public, including relevant recommendations of the protection measures to remind the public of air quality is not suitable for outdoor activities, and should as far as possible to take protection, reduced length of stay, reduce discharge of fireworks and Lantern Festival.
For public of questions, expert recommends, while Government the sector should strengthened collaboration, formed Heli, such as environmental and meteorological sector strengthened collaborative, improve air pollution forecast of accuracy, to guide government sector timely take should measures; on the, government sector in suffered pollution weather Shi should strengthened initiative, according to different warning level developed more refinement, and more with Executive sexual of should measures, such as in low level warning Shi, take limit bus travel, strict management big van, and muck car, and site Yang dust, Stimulate the positive energy of public participation in environmental protection.
At the same time, experts also suggested that should increase, "ten" and other regulations implementing, doing a zone defense of the Jing-Jin-JI-Lu-Yu, Jin, joint control, through the control and abatement of pollution, and fundamentally solve the problem of pollution.
新华网北京2月17日电(记者卢国强、倪元锦)北京这几天连续出现重污染天气，有些市民提出，面对重霾，北京为何未启动最高级别的空气重污染红色预警？政府部门采取了哪些应急措施？就此，记者采访了环保部门和部分专家学者。
疑问之一：北京为何未启动“空气重污染红色预警”？
释疑：北京市环保部门表示，根据监测数据，14日夜间，烟花爆竹燃放导致PM2.5峰值浓度超过500微克每立方米，由于大气静稳、扩散条件较差，PM2.5浓度下降缓慢，持续影响到15日，达到空气重污染“蓝色预警”标准。
14日8时和20时，环保部门按照2013年通过的《北京市空气重污染应急预案(试行)》的规定，两次发布全市启动“空气重污染应急蓝色预警措施”的信息。
15日下午，北京市环保监测中心判断，16日中午前后，全市自北向南空气质量将逐步改善。环保部门监测数据证实，到16日14时，北京城区与北部地区的PM2.5浓度显著下降。
也就是说，当时北京市的空气污染状况并没有达到“预测未来持续3天交替出现‘重度污染’或‘严重污染’”的橙色预警，或“预测未来持续3天出现‘严重污染’”的红色预警级别。
根据《北京市空气重污染应急预案(试行)》，当遭遇橙色预警时，采取“停产”“停工”“停放”“停烧”等强制性污染减排应急措施；遭遇红色预警时，还将增加机动车单双号限行，渣土、砂石等易扬尘的运输车辆停运，中小学和幼儿园停课等措施。
疑问之二：应对雾霾，政府采取了哪些应急措施？
释疑：《北京市空气重污染应急预案(试行)》规定，遇蓝色预警级别时，应向市民发布健康防护提醒措施，以及倡导自觉减少污染物排放的建议性污染减排措施。
北京环保部门表示，在空气污染情况达到蓝色预警级别后，已通过短信、微博、微信、互联网、车载电视等途径向公众发布了蓝色预警的相关建议性保护措施，提醒市民空气质量情况不适宜户外活动，出行应尽量做好防护、缩短停留时间，元宵节减少燃放烟花爆竹等。
针对公众的疑问，专家建议，一方面政府各部门应加强协作，形成合力，例如环保与气象部门加强协同，提高空气污染预测的准确度，以指导政府部门及时采取应对措施；另一方面，政府部门在遭遇污染天气时应加强主动性，根据不同预警级别制订更细化、更具执行性的应对措施，例如在低级别预警时，采取限制公车出行，严管大货车、渣土车、工地扬尘，激发公众积极参与环保的正能量。
同时，专家还建议，应加大“国十条”等法规的落实力度，切实做好京津冀鲁豫晋的区域联防联控，通过对污染源的控制和减排，从根本解决污染问题。
