The haze once again enveloped China.

The Ministry of Environmental Protection issued a report on February 24th. Satellite remote sensing monitoring showed that the area of ​​air pollution in the central and eastern regions of China was about 980,000 square kilometers on February 23, with a relatively heavy air pollution area of ​​about 800,000 square kilometers, mainly in Beijing. , Hebei, Shanxi, Shandong, Henan, Liaoning and other places. Compared with the 22nd, the area of ​​ash in Jiangxi, Shandong and Anhui provinces has decreased.

“The occurrence of such a large amount of haze on these two days is reminiscent of the severe haze at the end of October and January last year. It is embarrassing.” An official from the Ministry of Environmental Protection told reporters that the Ministry of Environmental Protection had 23 February. The 1.21 million square kilometers air pollution affected area reported on the 22nd was slightly smaller than the 1.3 million square kilometers in January last year.

According to a report from the Ministry of Environmental Protection, this heavy pollution weather will continue until the 27th. The reporter was informed that on the 22nd the Ministry of Environmental Protection had issued an emergency notice requiring all localities to do a good job of emergency warning and dispatched the North China Supervision Center to Xingtai and Baoding to supervise local emergency situations.

Prior to this, from February 16 to 21, the Ministry of Environmental Protection conducted special inspections on air pollution prevention and control in 12 cities in Beijing, Tianjin, Hebei and surrounding areas.

50 cities re-soaked in pollution

Compared with 22 days, the number of heavily polluted cities increased by 16 on the 23rd

The haze came back and it was amazing.

According to the person in charge of the Ministry of Environmental Protection, on February 23, out of the 161 cities that carried out new standards for air quality monitoring, 50 or more cities had serious or above pollution, of which 11 were serious 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 scope of pollution is mainly concentrated in Beijing-Tianjin-Hebei and its surrounding areas, as well as in the Midwest and Northeast regions, of which Beijing-Tianjin-Hebei and its surrounding areas are the most polluting.

In the Beijing-Tianjin-Hebei region and surrounding areas, there were 18 cities with serious and above pollution, which increased by 2 compared with the 22nd. Air pollution continues. Among them, the air quality in seven cities such as Xingtai, Handan, Yangquan, Zhangjiakou, Shijiazhuang, Hengshui, and Dezhou is heavily polluted, and 11 cities such as Beijing, Baoding, Chengde, Langfang, and Tangshan are heavily polluted. Compared with the 22nd, the air quality in two cities of Tianjin and Qinhuangdao improved from severe pollution to moderate pollution, and the air quality in Datong, Zibo, Chifeng and Binzhou decreased from light to moderate pollution to severe pollution.

The average daily PM2.5 concentration ranged from 56 micrograms/cubic meter (Qingdao) to 439 micrograms/cubic meter (mean) with an average of 174 micrograms/cubic meter; the PM10 daily mean concentration range was 87 micrograms/cubic meter (Qingdao)~ 623 μg/m3 (Xingtai), with an average of 248 μg/m3. Compared with the same period on the 22nd, the concentration of PM2.5 increased slightly, and the concentration of PM10 remained basically the same. Xingtai City is the most polluted city in the region, with an AQI value of 500 and severe air pollution. The AQI value in Beijing is 255 and the air quality is heavily polluted. The main pollutants are PM2.5 and PM10.

According to the introduction of the Ministry of Environmental Protection, as of 10:00 on February 24th, among the 161 cities, there were 57 cities with an average PM2.5 hour concentration of more than 150 micrograms/cubic meter, which was severe and above pollution. Among them, the average concentration of PM2.5 in 15 cities was greater than 250 micrograms/m3, which was a serious pollution. The average concentration of PM2.5 in Beijing was 234 μg/m3, and the air quality was heavily polluted.

On the haze, the person in charge of the Ministry of Environmental Protection analyzed on the 23rd that the reasons for the recent large-scale heavy air pollution are: First, the high intensity of pollution discharge, and the large amount of pollutants discharged; Second, unfavorable weather conditions, pollutants are difficult to timely The proliferation, especially in the Beijing-Tianjin-Hebei region, has weaker cold air power in recent days, less wind near the surface, more stable atmosphere, and the accumulation of pollutants. Third, the impact of air pollution caused by motor vehicles and winter coal-fired heating pollution in the north.

“The discharge of pollutants cannot be suddenly and massively increased. At the same time, the weather conditions are indeed worse than the meteorological conditions encountered by the previous two large-scale smog. We are not willing to suffer such severe haze. However, the formation and management of haze cannot really be accomplished overnight.” The aforementioned officials of the Ministry of Environmental Protection explained to the 21st Century Business Herald reporter.

According to Chai Fahe, the vice president of the Chinese Academy of Environmental Sciences, the haze is still so serious that we are doing analysis. “This shows that the emission reduction targets set by our past governance plans may not be sufficient. We must also increase emission reduction efforts. Only by persistently reducing emissions can we hope to see haze improve.”

According to the prediction of the Ministry of Environmental Protection, the atmospheric diffusion conditions will remain unfavorable from the 25th to the 26th. Northern Hebei is mainly moderately to heavily polluted, while Beijing, Tianjin, and central and southern Hebei are mainly heavy pollution. On the 27th, due to the influence of cold air, the conditions for atmospheric diffusion became favorable, and heavy air pollution in the Beijing-Tianjin-Hebei region was expected to ease.

Air Pollution Prevention and Control

Xingtai City Neiqi County Shunda Coking Co., Ltd. pollution control facilities are not operating properly.

The Ministry of Environmental Protection stated that in order to deal with the heavy pollution weather, a heavy pollution weather emergency response mechanism has been launched. According to the "Beijing-Tianjin-Hebei and Peripheral Heavy-Heavy Weather Surveillance and Early-Warning Plan," the China Meteorological Administration cooperated with the air quality of Beijing-Tianjin-Hebei and surrounding areas. Pollution weather monitoring, warning and forecast work.

Prior to this, the Ministry of Environmental Protection launched a five-day February special air pollution control inspection on February 16. The scope of supervision is Beijing, Tianjin, Tianjin, Shijiazhuang, Tangshan, Langfang, Baoding, Xingtai, Handan, Taiyuan, Baotou, Dezhou and Zhengzhou. There are 12 cities.

“According to the Detailed Rules for the Implementation of the Air Pollution Prevention and Control Action Plan for the Beijing-Tianjin-Hebei and Surrounding Areas, Beijing-Tianjin-Hebei and surrounding areas do not include Zhengzhou. However, when we drafted the Air Pollution Prevention Action Plan, we wanted to include Zhengzhou. In addition, Henan’s air pollution also deserves close attention,” Chai Fahe explained to reporters in the 21st Century Business Herald.

According to the deployment of the Ministry of Environmental Protection, the supervision includes the local government's implementation of the “10 Atmosphere” responsibilities, spot-checking the construction and operation of air pollution prevention and control facilities of key industrial enterprises of the department, and meeting the discharge standards; coal yards, stockpiles and slag dust Implementation of measures; supervision of local environmental protection agencies and related departments to check on the situation; spot checks on the construction site, transportation vehicles, dust from roads, fume purification in catering service industries, extreme burning of coal, coal quality control, etc. The functional departments inspected the development and implementation of responsibilities; “reviewed” the problems discovered during the previous inspections and urged the implementation of the rectification of the problems.

At present, the Ministry of Environmental Protection has notified law enforcement inspections in seven cities including Beijing, Zhengzhou, Xingtai, Dezhou, Shijiazhuang, Tangshan and Langfang. Among them, in the case of Xingtai City, the most polluted area in North China on February 23rd, the inspection found that there are four major problems: surface source pollution has not yet been effectively controlled, and backward production capacity that does not meet industrial policies still exists; More prominent; the degree of refinement of air pollution prevention work needs to be improved.

Among the second types of problems, some enterprises' production facilities do not comply with industrial policies and fall into the category of outdated production capacity, but they still produce as usual during inspections by inspection teams. During the unannounced visits, pollution control facilities of the Neiqiu County Shunda Coking Co., Ltd. in Xingtai City were not operating properly, and the phenomenon of unorganized emissions during coal charging and coking was very serious. Coal piles did not have effective coverage, and there were significant differences with the inspection.

The reporter and the North China Supervision Center participated in the special supervision of air pollution prevention in Taiyuan. The 21st Century Business Herald reporter found that Taiyuan City had achieved a series of results on the basis of the implementation of rectification by the Ministry of Environmental Protection after the previous inspection. However, it still found that there are problems in environmental management such as roads and construction sites.

Fifteen provincial capitals (including municipalities) in the “Twenty-two Districts” area outside Beijing and Tianjin and the surrounding areas, and four environmental protection supervision centers in south China, southwest, northwest, and northeast of the Ministry of Environmental Protection also conducted air pollution prevention and control. Special supervision.
