1、How poisonous will the air be after heavy fog falls? What does the air quality level 6 mean?
The Ministry of Environmental Protection announced the daily urban air quality report on January 12. The top 10 cities with the highest API pollution index are: Shijiazhuang in the first place, Handan in the second place, Baoding in the third place, Tangshan in the fourth place, Tianjin in fifth place, Zhengzhou in sixth place, Jinan in seventh place, Qinhuangdao in eighth place, Jining in ninth place, Urumqi and Wuhan in tenth place were tied. This ranking does not include PM2.5 and ozone pollution index.
In the past few days, haze weather has shrouded most of central and eastern China, and its momentum continues unabated. Heavy fog has caused serious air pollution. According to the national urban air quality real-time release platform of the China Environmental Monitoring Center, on the 12th, the air quality in Beijing, Hebei, Shandong and other places reached serious pollution, with the PM2.5 index approaching the maximum value.
Beijing's first "brown" face PM2.5 value exceeded 900
The "face" over Beijing began to become gloomy from the 11th, and the fog became thicker and thicker on the night of the 11th. The Beijing Meteorological Observatory reported on the 22nd A yellow fog warning was issued at 30:00. Until the morning of the 12th, the plain areas of Beijing were still shrouded in heavy fog, with visibility in the urban and southeastern areas less than 500 meters.
With the worsening of smog, Beijing’s air quality is getting worse and worse. As of 10:00 on the 12th, among the 35 monitoring stations in Beijing, 31 monitoring stations were all classified as Level 6 serious pollution, the highest level, displayed in maroon. This is the first serious pollution day Beijing has encountered since it officially started implementing new air quality standards this year. Data from the Beijing Environmental Monitoring Center shows that as of 18:00 on the 12th, the air quality in Beijing’s urban areas has reached serious pollution levels. The urban PM2.5 concentration is very high. PM2 in places such as the Temple of Heaven, Qianmen, East Fourth Ring Road, Chaoyang Agricultural Exhibition Hall, and Fengtai .5 concentration monitoring values are all around 750 micrograms/cubic meter (ie 0.075 mg/cubic meter), which is on the verge of "exploding". According to the "Ambient Air Quality Standards" announced by the State Council in February 2012, the annual and 24-hour average concentration limits of PM2.5 are set at 0.035 mg/cubic meter and 0.075 mg/cubic meter respectively. As of 23:00 in the evening, the real-time concentration of PM2.5 at monitoring points such as Xizhimen North, South Third Ring Road, and Olympic Sports Center in Beijing exceeded 900, and the Xizhimen North monitoring point reached a maximum of 993 micrograms/cubic meter.
Experts from the Beijing Environmental Monitoring Center said that judging from the analysis results of the pollution situation forecast, the heavy pollution process affecting Beijing this time will not be significantly improved before next Monday.
Severe pollution in many places has exceeded the upper limit of measurement
The air quality of many cities in Shandong, Hebei, Henan, Hubei and other places is also seriously polluted, with PM2.5 and PM10 monitoring indexes reaching peak values.
On the 12th, Jiangxi was hit by the largest dense fog since 2013. Many counties and cities experienced heavy fog with visibility less than 500 meters, and visibility in some areas was less than 50 meters.
At 7:05 on the 11th, the Sichuan Provincial Meteorological Observatory issued the No. 5 orange fog warning. Visibility in some places will be less than 200 meters. On the 11th, the Chengdu Municipal Environmental Protection Bureau released an air quality daily report and forecast. Due to heavy fog, the air quality level in the main urban area of Chengdu on the 11th and 12th was slightly polluted.
The reporter saw from the Hebei Province Air Quality Automatic Release System that at 16:00 on the 11th, the air quality of the 11 districts and cities in Hebei Province except Chengde was "severely polluted" and Zhangjiakou was "excellent", and the remaining 9 cities All are "severely polluted". Among them, the air quality index in Shijiazhuang, Handan, Xingtai and Hengshui is even "off the charts", with values reaching or exceeding the upper limit of measurement of 500. The primary pollutants are mostly PM2.5 and PM10.
The ambient air quality monitoring data of Tianjin Environmental Protection Bureau shows: around 7 pm on the 11th, among the 17 monitoring stations in Tianjin, the ambient air quality index (AQI) of 16 monitoring stations in the last 24 hours was above 300. It is classified as "severe pollution".
As of 17:00 on the 11th, the air quality index of nine monitoring points in Wuhan's urban areas was all above 200. It is understood that this is the fifth severely polluted day since Wuhan entered the New Year, and the primary pollutant is PM2.5. The air quality index at some monitoring points once exceeded 300 on the 10th, setting a record for the most serious air pollution in the new year.
Forecast experts from the Henan Meteorological Observatory explained that due to the recent stable atmosphere structure, high air humidity near the ground, weak surface pre ssure field, low wind, and low night temperatures, heavy fog appears. Since the atmosphere is in a stable state, there is neither vertical movement nor horizontal flow, so pollutants in the air cannot diffuse, resulting in haze.

Lyrics:
North wind passing by this lonely city
Instantly cold
Dust flooded the whole sky
Like my lost dream
br/>The dim street lights lengthen my figure
Who is walking with me in the wind and fog
I am a drifting bottle floating in this city
I don’t know when the dream in my heart will be realized
/>The north wind passed by this lonely city
It was instantly cold
Dust flooded the entire sky
Like my lost dream
The dim street lights lengthened my figure
Strong wind Who is walking with me in the fog
I am the drift bottle floating in this city
Floating with the waves in the vast sea of people
I am the drift bottle floating in this city
I don’t know when the dream in my heart will come true
I am a drifting bottle floating in this city
Floating with the waves in the vast sea of people
I am a drifting bottle floating in this city
I don’t know when the dream in my heart will come true
I am a drifting bottle floating in this city
Floating with the waves in the vast sea of people
I am a drifting bottle floating in this city
I don’t know when my dream will come true
