Fuzhou smog Fujian smog

1. What are the causes of air pollution in Fuzhou? 2. Why is there no smog in Fujian? 3. How many days does the smog last? 4.20 14 ranking of smog days in cities. What are the causes of air pollution in Fuzhou?

Because Gushan is located near Mawei, Fuzhou, where heavy industry is concentrated, Fuzhou Thermal Power Plant is the most polluted, which is the national key pollution monitoring unit. In other words, if the site is closed, there is no electricity in Fuzhou and surrounding cities. As long as the site is closed, the air in Fuzhou will be better than that in Haikou, ranking first in all major cities in China.

Around 2020, because Fuzhou will plan the subway airport line, Changle City and Fuzhou City will merge to open up a new Changle District, and the subway will pass near Gushan. Therefore, the government can consider moving the site to Pingtan Comprehensive Experimental Zone or replacing the existing equipment with more advanced energy. But this is still an armchair strategist. The last big chimney in the center of Beijing was closed on 20 16, so a second-tier backward city like Fuzhou will have to wait until at least 2022. So your place is a special area for discharging pollutants.

Fuzhou is surrounded by mountains in the northwest, with low terrain and a large gap in the southeast. In summer, the northwest wind blows pollutants directly to Taipei.

Therefore, Taipei has the best air quality in China. Under normal circumstances, pm2.5 is a single digit (below 8, the China measurement standard is below 20 every day; However, the pollutant discharge in Fuzhou will also be affected to some extent.

The southeast wind is powerful in summer, and the pollutants blown into the urban area will not bring any pollution to the urban area.

Therefore, the air in Fuzhou Third Ring Road is still guaranteed. As a result, house prices soared.

Why is there no smog in Fujian?

On the one hand, thanks to Fuzhou's unique diffusion conditions, Fuzhou's atmospheric structure is not "lifeless", and air flows, even if there are pollutants, it is easy to be blown away. On the other hand, the topography of Fujian, such as Wuyishan Mountains, makes it difficult for foreign pollutants to spread to Fuzhou. In addition, Fuzhou does not have a lot of industrial and traffic exhaust emissions like Beijing and Tianjin.

For the smog weather in Nanping and Ningde, some environmental experts said that the environmental protection departments in Nanping and Ningde have not carried out PM2.5 monitoring, and it is impossible to know whether PM2.5 exceeds the standard, so it is impossible to judge whether there is smog.

The smoke lasted for several days.

Beijing, 65438+ 10, 13 (Xinhua) In recent days, the central and eastern regions of China have been continuously affected by smog weather, which will continue in the next few days, and various localities have started to take countermeasures. Orange warning. According to the forecast, the seriously polluted air quality in this city will continue in the next three days.

Beijing PM2.5 index 12 is on the verge of "breaking the chart", and the air quality continues to be seriously polluted at level 6. According to the data of Beijing Environmental Monitoring Center, as of 13 10, the air quality of all monitoring stations in the urban area was at a serious pollution level, and the air quality index AQI of all stations reached a peak of 500 except Haidian North New District and Haidian Botanical Garden.

According to the live data released by 12 19, the ambient air quality index AQI of Changchun is 3 12, which shows that it is seriously polluted.

Hebei Meteorological Observatory issued an orange warning signal for fog and haze on 13 16. It is estimated that there will be haze in the south of Tangshan, the south of Qinhuangdao, Baoding, Langfang and the south of the area from the night of 13 to the day of 14, and the local visibility is less than 200 meters.

From October 6th to October 2nd, 65438/kloc-0, the air quality in Nanjing's built-up area reached the pollution level for seven consecutive days. Some surrounding cities have also experienced air pollution simultaneously, showing regional pollution characteristics.

13 At 8 o'clock that night, the AQI index of all stations involved in PM2.5 in Changsha exceeded 200, which was "severe pollution", and the monitoring value of some stations exceeded 300, reaching "serious pollution".

Local environmental protection, health, transportation and other departments take measures to deal with it.

In the face of smog, all localities are launching countermeasures.

Beijing Environmental Protection Monitoring Center, through the official Weibo, advised the public to avoid going out and strenuous exercise as much as possible. The Beijing Municipal Environmental Protection Bureau announced that it will continue to implement the measures of emergency plan for heavy air pollution day. At the same time, the public is advised to travel by bus as much as possible to reduce pollutant emissions. Relevant departments, districts and counties have taken measures such as urging relevant pollutant discharge units to reduce pollution emissions, reducing the scale of earthwork operations on construction sites, and increasing cleaning and cleaning operations. For areas where the AQI index is predicted to reach 500, the measures of extremely heavy pollution day will be launched, and the party and government organs will take the lead in stopping 30% of buses.

The Beijing Municipal Education Commission launched an emergency plan on June 5438+02, requiring district and county education commissions in heavily polluted areas to immediately notify their primary and secondary schools to stop students' outdoor exercise activities in the next three days. The Beijing Municipal Transportation Commission has made overall arrangements for safeguard measures, and the rail transit operators are ready to increase temporary trains and strengthen the flow of people.

In addition to Beijing, various localities have also taken corresponding measures. The Meteorological Bureau of Jilin Province and the Health Department of Jilin Province jointly issued a yellow warning for meteorological conditions of respiratory diseases such as colds, cardiovascular and cerebrovascular diseases, and the traffic control department launched a secondary plan for bad weather traffic management;

Hebei Meteorological Bureau started the response to major meteorological disasters on 10 on 17; Nanjing Environmental Protection Bureau and Meteorological Bureau have started artificial rainfall mechanism, implemented artificial rainfall in a timely manner, and strengthened supervision over industrial enterprises;

Zhengzhou Municipal Transportation Commission restricted buses with excessive emissions, and at the same time strengthened the supervision and management of dust on the construction site, and ordered 15% of the construction site to stop construction. In addition, the emergency plan for heavy polluted weather in Zhengzhou has been formulated and is being gradually implemented;

Wuhan Environmental Protection Bureau issued an early warning of ambient air quality, strictly supervised the smoke and dust emissions of industrial enterprises, and ensured that the standards were met;

Changsha Environmental Protection Bureau has launched an emergency plan, including further strengthening dust control at the construction site, implementing vehicle exhaust detection, studying the elimination of yellow label vehicles, and increasing the emission reduction of nitrogen oxides in cement plants and thermal power plants.

The reporter learned from the environmental protection department that Jilin Province has not yet issued an emergency plan for heavy air pollution, and relevant policy plans are still in the pipeline.

Experts suggest that all provinces, autonomous regions and municipalities should establish a joint prevention and control mechanism.

Chen Ying, a professor in the Department of Environmental Science and Engineering at Fudan University, believes that the recent smog weather is the result of the combined action of pollutant discharge and atmospheric conditions.

Chen Ying said that the government should have a plan to deal with these heavily polluted weather. She suggested that from the perspective of pollution sources, reducing vehicle pollution emissions, including the government itself reducing the number of buses on the road, taking the lead in stopping driving, and advocating people to travel less and drive less; Urge key emission reduction enterprises, especially coal-fired enterprises, to study the possibility of stopping production with reference to the Beijing Olympic Games; Because the dust on the construction site is an important source of pollutants, the construction unit on the construction site is required to suspend operations.

However, because the atmosphere is greatly influenced by the surrounding areas and is regional, if only one city takes these measures, the effect is not obvious; For air pollution, it is necessary to establish a joint prevention and control mechanism for all provinces, autonomous regions and municipalities.

Chen Ying reminded that pathogen pollution is heavier and more active in winter influenza and smog weather. In addition to reducing outdoor activities, citizens should also pay attention to preventing influenza. Chen Ying reminded that the impact of PM2.5 pollution on health may not show up immediately, but may appear in a month or several months, so citizens should pay attention to their health. She also suggested that the government should give real-time warning to encourage citizens to work at home. If the smog persists, kindergartens and primary and secondary school students are advised to suspend classes.

Fuzhou News Network February 3 rd Yesterday, the website of the Ministry of Environmental Protection released the air quality status of key areas and 74 cities in 20 14, ranking seventh in Fuzhou and eighth in Xiamen.

According to reports, the former 10 cities with relatively good air quality in 20 14 were Haikou, Zhoushan, Lhasa, Shenzhen, Zhuhai, Huizhou, Fuzhou, Xiamen, Kunming and Zhongshan; The top 10 cities with relatively poor air quality are Baoding, Xingtai, Shijiazhuang, Tangshan, Handan, Hengshui, Jinan, Langfang, Zhengzhou and Tianjin. According to the ambient air quality standard, in 20 14 years, the fine particles (PM2.5, PM 65438) in key areas such as Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta, and in 74 municipalities directly under the central government, provincial capital cities and cities with separate plans, Haikou, Lhasa, Zhoushan, Shenzhen, Zhuhai, Fuzhou, Huizhou and Kunming,

In 20 14, Fuzhou's air quality fell out of the top ten, why can it rank seventh in the final comprehensive ranking? Environmental experts in Fuzhou believe that compared with other cities, Fuzhou's air quality is relatively stable and has little fluctuation due to meteorological influence. Although it once fell out of the top ten, it still ranks in the forefront of the country.

Yesterday, the air rankings of 20 14 and 12 in nine cities in Fujian Province were also released simultaneously, and Fuzhou ranked fourth. The proportion of days when the ambient air quality reached the standard in nine cities in the province was 93.5%~ 100%, and the average rate of reaching the standard was 98.9%, which was the same as 165438+ 10. According to the comprehensive index of air quality from low to high (that is, the air quality from good to bad), the ranking of cities divided into districts is: Ningde, Putian, Quanzhou, Fuzhou, Zhangzhou and Longyan (tied for fifth place, Xiamen, Nanping and Sanming.
