Nearly 60% of Beijing's air quality is excellent this year. What does this mean?

It shows that the air quality in Beijing has improved this year.

According to this year's press release, the average number of excellent days from 1 to 10 in Beijing was 58.3%, up 0.6 percentage points year-on-year. The concentration of PM2.5 was 60 μ g/m3, down 6.2% year-on-year; The concentration of PM 10 was 86 μ g/m3, up by 10.3% year-on-year. This shows that Beijing's environmental protection is getting better and better, and the air quality will slowly pick up.

As we all know, the air quality has been getting worse and worse in recent years, especially in Beijing. And what impact will the deterioration of air quality have on us? Starting from the harm to human body, smog can induce respiratory diseases, cardiovascular and cerebrovascular diseases and various bacterial diseases, which greatly increases the probability of people suffering from cancer. And gloomy weather can also make people feel bored and depressed. The severity of smog reduces visibility, and only a few meters can be seen in severe cases, which greatly increases the frequency of accidents. Therefore, before Beijing, the necessary thing for people to travel was masks, and various anti-fog masks began to sell well.

Therefore, in recent years, China began to invest in smog control. First of all, measures to reduce coal consumption have been stepped up, so that many areas have begun to realize coal-free, and coal-fired boilers with 10 tons and below have been completely eliminated. The annual coal consumption has been reduced by 30%, and the total amount has been reduced to less than 7 million tons. Secondly, do a good job in the control of heavy-duty diesel vehicles, supply the sixth stage of refined oil, eliminate old motor vehicles and further promote new energy vehicles. Intensify industrial pollution control and emission reduction, complete the low-nitrogen transformation of 65438+100000 steam gas boilers, accelerate the implementation of the low-nitrogen transformation of Yanhua, and clean up and rectify 2570? Loose dirt? Enterprise. Strictly control dust pollution and carry out special positive value of muck trucks. Establish an environmental protection police force, strengthen environmental supervision and law enforcement, and severely punish illegal emissions. Finally, increase greening, many places have begun to implement the third generation of housing, which has a strong greening function.

Judging from the air quality in Beijing this year, we can see that Beijing has gradually improved its air quality, and gradually all parts of the country will increase air control efforts and return us to a green earth.
