 Shanghai air pollution opponent change: from PM2.5 to nitrogen dioxide ozone


In April 26th, Shou Ziqi, director of the Shanghai Environmental Protection Bureau, visited the 2018 peoples livelihood interview. Wang Weiqiu in the Orient network The rival of air pollution control in Shanghai is changing from PM2.5 to nitrogen dioxide (NO2) and ozone. In April 26th, Shou Ziqi, director of the Shanghai Environmental Protection Bureau, made a visit to the 2018 peoples livelihood interview. Although the Shanghai PM2.5 and PM10 had reached the national goal of assessment in 2017, the index of nitrogen dioxide and ozone did not reach the national standard of environmental air quality two. Shou Ziqi said, recently launched the Shanghai air heavy pollution special emergency plan (2018 Edition), the early warning starting conditions are re optimized and adjusted, when the prediction of heavy pollution at least one day in advance early warning, in addition to the Yangtze River Delta linkage. In the future, the Shanghai environmental protection department will further investigate the key industries such as petrochemical, chemical, packaging and printing, industrial painting and other key industries, and strive to reduce the average annual concentration of the PM2.5 in Shanghai to 37 microgram / cubic meter in 2020, and the coordinated control of the PM2.5 and ozone pollution will be more prominent in the next five years. The opponent is changing from PM2.5 to nitrogen dioxide and ozone The number of excellent days in 2017 has increased by 34 days over 2013, so that all of us can breathe more than a month of good air. During the interview with the people, Shou Ziqi said that in 2017, the Shanghai air quality index (AQI) rate was 75.3%, which meant that more than 3/4 of the year had no air pollution. Moreover, the number of days of severe daily pollution reached only 2 days, which was 21 days less than that in 2013. However, although both PM2.5 and PM10 in Shanghai had reached the national goal of assessment in 2017, the index of nitrogen dioxide and ozone did not reach the two level of national environmental air quality standards. The annual average concentration of the former is 44 micrograms per cubic meter, which is 2.3% higher than that in 2016. The average annual ozone concentration is 181 micrograms / cubic meter, which is 17 micrograms / cubic meter higher than that in 2016. Shanghai municipal government executive meeting recently passed the Shanghai air heavy pollution special emergency plan (2018), Shou Ziqi said, this is compared with the 2016 edition of the plan, there are three changes. First, the early warning conditions are optimized and adjusted, and the prediction results are taken as the starting conditions to increase the early-warning amount. He said that when forecasting heavy pollution, we should start early warning at least one day in advance. The two is to reduce the threshold for early warning. For example, yellow warning is changed from two days severe pollution to one day severe pollution. At present, the threshold of Shanghai has been the lowest in the Yangtze River Delta region and all the cities where air quality is not up to standard. The picture comes from FM official micro-blog With the reduction of starting threshold, the number of early warning of air heavy pollution in this city will increase more than the original plan, Shou Ziqi explained. But please rest assured that this does not mean that the air quality is worse, but the areas, departments and related units are not seriously polluted when the pollution level is not serious, so the emergency emission reduction is carried out ahead of time. Try to ease the degree of air pollution. The average annual concentration of PM2.5 in 2020 is below 37 micrograms Shou Ziqi also talked about Shanghais recent clean air action plan (2018-2022), which will improve the efficiency of environmental law enforcement from three aspects of law enforcement, law enforcement and law enforcement to ensure the effectiveness of atmospheric governance. When Shou Ziqi introduced a new round of plans, the law enforcement content, Shanghai will focus on key areas, key industries (petrochemical, chemical, packaging, printing, industrial coating, etc.) and key pollutants as the main control object. Specifically, the central urban area in combination with regional environmental management needs to focus on special law enforcement in catering, steam repair, dry cleaning and other industries. According to the distribution of regional industry, the suburb focuses on the special law enforcement of industrial waste gas produced by painting and printing. On the enforcement measures, we will make full use of new measures, such as daily penalty, stop production, limit production, seizure, detention and transfer of detention. In 2017, the city made 61 cases of daily punishment, and the amount of punishment was about 95000000; the seizure of 179 pieces, the limited production and suspension of 30 pieces, the administrative detention of the public security and the suspected crimes were 86, and the environmental violations were greatly compromised. Shou Ziqi said. Besides, it is another important task to give full play to the joint prevention and control of air pollution in the Yangtze River Delta. Shou Ziqi introduced that, on the one hand, more efforts should be made to promote the implementation of the national ten air articles, and the three provinces and one city have completed the key tasks one year ahead of time. On the other hand, combining the characteristics of the Yangtze River Delta, seize the common problems, jointly promote the construction of motor vehicle coordination and ship emission control areas, and build a regional air quality forecast system. It has realized the sharing of regional monitoring data. In 2017, the average concentration of PM2.5 in the 25 cities of the Yangtze River Delta was 44 micrograms per cubic meter, which was 34.3% lower than that in 2013. The main goal of the new clean air action plan has been clear: by 2020, the average annual concentration of PM2.5 is striving to reach 37 micrograms per cubic meter; the air quality rate (AQI) will strive to reach about 80%, and the heavy pollution weather is basically eliminated. By 2022, the average annual concentration of PM2.5 will be below 35 micrograms / cubic meter, and the air quality and good quality (AQI) will be further enhanced. PM2.5 and ozone pollution will be co controlled Shou Ziqi introduced the characteristics and key points of air pollution control in Shanghai in the next five years. There are three aspects of air pollution control in the next five years. First of all, the environmental protection department focuses on the industry and transportation areas on the focus of the work, co-ordinate the fields of energy, construction, life and agriculture, and deepen the prevention and control of air pollution in an all-round way. Secondly, on the key measures, the dual control of energy and coal is carried out, the structural adjustment of key areas and key industries is accelerated, the transportation system is optimized and the total quantity control system of volatile organic matter is established. Third, on the control index, the key points are fine particles, nitrogen oxides and volatile organic compounds, and the control of ozone pollution is taken into consideration, and the coordinated control and emission reduction of various air pollutants are promoted. All of the above work has been written into the new clean air action plan. Shou Ziqi said that the new version of the action plan combs 131 main measures, among which six are 88 governance measures and 43 are safeguards. For example, in the field of energy, Shanghai will continue to adhere to control and control and implement the dual control of energy and coal consumption. By 2020, the total amount of energy consumption was under 1.24 million tons of standard coal, and the total amount of coal consumption in the city was reduced by more than 5% on the basis of 2015. In the field of industry, we should deepen the optimization and adjustment of the industrial structure of the key areas and complete a new round of comprehensive environmental renovation in the Jinshan area by 2020, and complete the structural adjustment of the Wujing industrial zone and the high and chemical areas. Strengthen the governance of Bao Wu group, Shanghai Petrochemical Company, Huayi Group, and deepen the management and supervision of volatile organic compounds.
