In the first half of the year, the air quality in Shanghai was the best level in the past 8 years.

Crystal sky, double rainbow, and the sunset with red half of the sky, the summer beauty has become the "standard" of the recent circle of friends in Shanghai. In recent years, the city's ecological environment has continued to improve. Today (6th), Cheng Peng, director of the Municipal Bureau of Ecology and Environment, revealed in the "2022 People's Livelihood Interview" that in the first half of this year, Shanghai's air quality has been further improved, and many indicators are the lowest level in the past 8 years.

Not only that, the "greasy" trouble brought by the fireworks of the restaurant, the problem of disturbance caused by the square dance and drag racing "bombing street", when the "carbon points" accumulated by low -carbon behavior can be converted into real benefits ... These citizens care about Specific environmental issues have also responded and improved.

Crystal sky is resident, Shanghai's ecological environment continues to improve

In 2021, 335 days of environmental air quality in Shanghai reached excellent level, and the excellent rate of environmental air quality index (AQI) was as high as 91.8%, which is the best year of air quality over the years. In the first half of this year, Shanghai refreshed a new record- "In the first half of this year, Shanghai's overall air showed a improving trend. Most indicators were the lowest in the same period in the past 8 years." Cheng Peng said.

The quality of air is getting better and better. For citizens, the most intuitive feeling is that there are more and more crystal sky, and for the environmental protection department, the change of the environmental air quality index (AQI) is concerned. Cheng Peng explained that the AOI index includes six pollutants monitoring indicators such as fine particles (PM2.5), inhalation particulate matter, sulfur dioxide, nitric oxide, ozone and carbon dioxide.

Among them, PM2.5 was the main pollutant that made people "smell the color change", and during the "Thirteenth Five -Year Plan" period, Shanghai has exceeded the restraint indicator of this ecological environment (PM2.5 national indicators 37 micrograms/cubic meter, Shanghai is 32 micrograms/cubic meter PM). Last year, the average concentration of Shanghai PM2.5 decreased to 27 micrograms/cubic meters, which was the lowest value for monitoring records.

However, the concentration of ozone pollutants has increased in recent years. According to Cheng Peng, in the first half of this year, the city's oxygen concentration was 156 μg/m3, an increase of about 10%compared with the same period last year. Not only that, since 2017, ozone has exceeded PM2.5 for 5 consecutive years to become the main pollutant in our city.

Isn't ozone an important substance that blocks ultraviolet to protect the earth? How to become pollutants? Cheng Peng said: "Actually, ozone is also divided into good 'ozone and' bad 'ozone." In addition to absorbing the "good" ozone of the sun's ultraviolet radiation, ozone with high ground concentration near the ground will cause asthma, respiratory tract infection, etc. The disease has become ozone pollution. He further stated that in the second half of the year, the municipal ecological environment department will do a good job in the collaborative emission reduction of volatile organic matter and nitrogen oxides, and strengthen the control of oxygen pollution. "Multi -polluting objects will be the focus of the continuous improvement of Shencheng's future air quality."

Plaza dances to disturb the people to rely on, and fireworks are no longer "greasy"

In addition to the blue water and blue sky, the citizens of Shanghai also care about the environmental issues of a lot of subtle places. During the live broadcast, some citizens called to ask. The recently opened food and supper also brought pollution of oil fume. What should I do? Cheng Peng introduced that in recent years, in order to effectively prevent oil and control pollution, the municipal ecological and environmental department has established a pollution control system with source prevention, process control, and severe consequences.

According to him, in the management of oil fume pollution of key catering enterprises in the city, many districts have explored many good methods for refined management: for example, the "Green Shield" data platform has been built in Jing'an District to open up the parties of the catering environment management. Data interaction channels and sharing environmental management information; Xuhui District has prepared a negative list of catering and selection sites to guide enterprises to reasonably choose catering business addresses; and Huangpu District successfully negotiated the ecological compensation case of catering oil smoke emissions exceeding standards, promoting enterprises to enhance environmental awareness ... Mowing

In addition to the oil fume, in the hot summer, the citizens who opened the windows to get cold have more troublesomeness of noise pollution. Cheng Peng responded that since the "Sixth Five -Five Environment Day" this year, the new "Noise Law" was officially implemented. Compared with the old version, the new "Noise" has increased the object of prevention and control, expands the scope of legal applications, and focuses on the difficulties of noise such as square dance, motor vehicle roaring "bombing streets", and bars.

In addition, Cheng Peng said that in the "Carbon and Benefit" that citizens care about, the "Shanghai Carbon Puhui System Construction Work Plan" has been soliciting opinions from the society in February. At present, the "Plan" is undergoing expert demonstration and risk evaluation. Prepare to be introduced in the second half of the year. "For example, in the fields of new energy, public transportation, low -carbon consumption, Shanghai will first carry out pilot demonstrations, connect the Shanghai carbon market, explore multi -level elimination channels, and explore the establishment of regional personal carbon accounts."
