Heavy haze locks 50 cities again

haze once again shrouds China< The Ministry of environmental protection issued a circular on February 24, and satellite remote sensing monitoring showed that the air pollution affected area in central and eastern China on February 23 was about 980000 square kilometers, of which the air pollution area was about 800000 square kilometers, mainly concentrated in Beijing, Hebei, Shanxi, Shandong, Henan, Liaoning and other places. Compared with the 22nd, the haze area in Jiangxi, Shandong, Anhui and other provinces decreased “in the past two days, there has been such a large-scale haze, which is reminiscent of the severe haze at the end of October 2011 and last January, and makes people feel palpitating.” An official of the Ministry of environmental protection told reporters that the air pollution affected area of 1.21 million square kilometers reported by the Ministry of environmental protection on February 23 was slightly smaller than that of 1.3 million square kilometers in January last year< According to the announcement of the Ministry of environmental protection, this kind of heavy pollution weather will last until the 27th. The reporter learned that on the 22nd, the Ministry of environmental protection has issued an emergency notice, requiring all localities to do a good job in emergency early warning, and sent the North China 1nspection Center to Xingtai and Baoding to inspect the local emergency situation previously, from February 16 to 21, the Ministry of environmental protection carried out special supervision on air pollution prevention and control in 12 cities in Beijing, Tianjin, Hebei and surrounding areas 50 cities fell into heavy pollution again compared with the 22nd, the number of heavily polluted cities increased by 16 on the 23rd the haze made a comeback, with amazing momentum< According to the introduction of the person in charge of the Ministry of environmental protection, on February 23, among the 161 cities that carried out the monitoring of the new air quality standards, 50 cities suffered from severe pollution or above, of which 11 cities suffered from severe pollution. Compared with the 22nd, the number of heavily polluted cities increased by 16, and the number of heavily polluted cities increased by 1. The pollution areas are mainly concentrated in Beijing Tianjin Hebei and its surrounding areas, as well as the central and western regions and Northeast China, of which Beijing Tianjin Hebei and its surrounding areas are the most polluted in Beijing Tianjin Hebei and its surrounding areas, 18 cities suffered from severe pollution or above, two more than on the 22nd, and the air pollution is still continuing. The air quality of 7 cities including Xingtai, Handan, Yangquan, Zhangjiakou, Shijiazhuang, Hengshui and Dezhou was seriously polluted, and 11 cities including Beijing, Baoding, Chengde, Langfang and Tangshan were heavily polluted. Compared with the 22nd, the air quality of Tianjin and Qinhuangdao improved from heavy pollution to moderate pollution, while the air quality of Datong, Zibo, Chifeng and Binzhou decreased from light to moderate pollution to heavy pollution< The daily mean concentration of PM2.5 ranged from 56 μ g / m3 (Qingdao) to 439 μ g / m3 (Handan), with an average of 174 μ g / m3; The daily mean concentration of PM10 ranged from 87 μ g / m3 (Qingdao) to 623 μ g / m3 (Xingtai), with an average of 248 μ g / m3. Compared with the same period on the 22nd, the concentration of PM2.5 increased slightly, while the concentration of PM10 was basically the same. Xingtai City is the most polluted city in the region, with AQ1 value of 500, and the air quality is seriously polluted. The AQ1 value of Beijing is 255, and the air quality is seriously polluted. The main pollutants are PM2.5 and PM10 according to the Ministry of environmental protection, as of 10:00 on February 24, there were 57 cities with PM2.5 hourly average concentration greater than 150 μ g / m3, which was severe or above pollution. The average concentration of PM2.5 in 15 cities is more than 250 μ g / m3, which is a serious pollution. The hourly average concentration of PM2.5 in Beijing is 234 μ g / m3, and the air quality is heavily polluted< According to an analysis of the haze on the 23rd, the person in charge of the Ministry of Environmental Protection said that the main reasons for the recent large-scale heavy air pollution are as follows: first, high pollution emission intensity and large amount of pollutants; Second, the meteorological conditions are unfavorable, so it is difficult for pollutants to spread in time, especially in the Beijing Tianjin Hebei region in recent days, the cold air force is weak, the wind near the ground is small, the atmosphere is relatively stable, and pollutants are easy to form accumulation effect; Third, motor vehicles and coal-fired heating pollution in northern winter have an impact on air quality “it is impossible to increase the emission of pollutants on a large scale suddenly, and the meteorological conditions this time are more unfavorable than those encountered in the previous two large-scale haze. None of us would like to encounter such a serious haze, but the formation and governance of haze can not be completed overnight. ” The Ministry of environmental protection official explained to the 21st century economic report reporter< According to Chai fahe, vice president of the Chinese Academy of Environmental Sciences, the haze is still so serious this time, and we are also doing the analysis" This shows that the emission reduction targets set in our past haze control plan may not be enough, and we need to increase the intensity of emission reduction. Only by persisting in emission reduction can we see the hope of improving haze. "< According to the prediction of the Ministry of environmental protection, from 25th to 26th, the atmospheric diffusion conditions will remain unfavorable, with moderate to severe pollution in northern Hebei and severe to severe pollution in Beijing, Tianjin and central and Southern Hebei. On the 27th, affected by cold air, atmospheric diffusion conditions turned favorable, and heavy air pollution in Beijing Tianjin Hebei region is expected to ease special supervision and re action of air pollution prevention and control the pollution control facilities of Shunda Coking Co., Ltd. in Neiqiu County of Xingtai City did not operate normally the Ministry of Environmental Protection said that in order to cope with the heavy pollution weather, it has launched the heavy pollution weather emergency mechanism, and cooperated with the China Meteorological Administration to do a good job in the monitoring, early warning and forecast of heavy pollution weather in Beijing, Tianjin and Hebei and its surrounding areas in accordance with the heavy pollution weather monitoring and early warning plan for Beijing, Tianjin and Hebei and its surrounding areas previously, the Ministry of environmental protection launched a five-day special supervision action on air pollution prevention and control in February on February 16. The scope of supervision covers Beijing, Tianjin, Hebei and the surrounding areas of Beijing, Tianjin, Shijiazhuang, Tangshan, Langfang, Baoding, Xingtai, Handan, Taiyuan, Baotou, Dezhou and Zhengzhou, with a total of 12 cities “according to the detailed rules for the implementation of the air pollution prevention and control action plan in Beijing Tianjin Hebei and its surrounding areas, Zhengzhou is not included in Beijing Tianjin Hebei and its surrounding areas. However, when we drafted the air pollution prevention and control action plan, we wanted to include Zhengzhou, and the air pollution in Henan also deserves close attention.” Chai fahe explained to reporters of the 21st century economic report according to the deployment of the Ministry of environmental protection, the contents of supervision include the implementation of the “ten air regulations” by the local government, the construction and operation of the air pollution prevention and control facilities of the key industrial enterprises of the Department, and the emission up to the standard; 1mplementation of dust prevention measures for coal yard, material pile and slag yard; Supervise the inspection of local environmental protection departments and relevant departments; Spot check the construction site of construction projects, transport vehicles, road dust, cooking fume purification of catering service industry, scattered burning of coal, coal quality control, etc., and supervise the implementation of inspection and responsibility of relevant local functional departments; To “look back” on the problems found in the early supervision and urge the rectification and implementation of the problems at present, the Ministry of environmental protection has informed the inspection of law enforcement in Beijing, Zhengzhou, Xingtai, Dezhou, Shijiazhuang, Tangshan and Langfang. Taking Xingtai City, the most polluted city in North China on February 23, as an example, the inspection found that there were four main types of problems: non point source pollution had not been effectively controlled, and there were still backward production capacity that did not conform to the industrial policy; The phenomenon of scattered burning of coal is prominent; The refinement of air pollution control needs to be improved among the second kind of problems, some enterprises’ production facilities are not in line with the industrial policy and belong to the category of backward production capacity elimination, but they still produce as usual when inspected by the inspection team. During the covert visit, the pollution control facilities of Shunda Coking Co., Ltd. in Neiqiu County of Xingtai City did not operate normally, the phenomenon of unorganized discharge in the process of coal loading and coking was very serious, and the coal pile was not effectively covered, which was significantly different from that during the investigation the reporter and the North China inspection center participated in the special inspection of Taiyuan air pollution prevention and control. The reporter of 21st century economic report found that Taiyuan city has achieved a series of results on the basis of the implementation of rectification after the early supervision of the Ministry of environmental protection, but still found that there are some problems in the environmental management of roads and construction sites in 15 provincial capital cities (including municipalities directly under the central government) in other “two districts and ten groups” regions outside Beijing, Tianjin and Hebei and the surrounding areas, the Ministry of environmental protection’s four environmental protection supervision centers in South China, southwest, northwest and northeast also carried out special supervision on air pollution prevention and control this article is a reprint of 1nternet media, which only represents the author’s point of view and has nothing to do with this website. 1f the information column articles and comments violate your legal rights, please call to let us know and we will deal with them in time
