How is the progress of ozone pollution control in China?

In 1979, ozone has been used as the environmental quality standard, which is expressed as the maximum concentration per hour. Although it was a standard, it was not enforced everywhere at that time. Only a few monitoring stations in Beijing, Guangzhou, Lanzhou, Shanghai and other cities monitored it, but not many people paid attention to it. In 20 12, a new ambient air quality standard was formulated, which was implemented nationwide in early 20 16. The control standard of ozone pollutants was increased, and the index of 8 hours was increased.

Controlling ozone pollution is more challenging than controlling PM2.5 and other air pollutants, especially when the smog has not dispersed, and the ozone problem has become an environmental issue of public concern. ?

In some provinces of China, the problem of overcoming ozone pollution has also emerged. ?

For example, Tianjin Environmental Protection Bureau has formulated a 20 17 special rectification action plan for volatile organic compounds and ozone, focusing on industrial emissions, wall painting and decoration, spray car repair, open-air barbecue, catering fumes and so on. And implemented in May this year.

The 11th Party Congress of Shanghai proposed that in the next five years, it is necessary to "take the control of PM2.5 and ozone concentration as the primary task, and further promote the joint prevention and control of air pollution in the Yangtze River Delta region, so that ordinary people can see a bluer sky and breathe fresher air";

The 11th Party Congress of Guangzhou also proposed to carry out the action plan for air pollution prevention and control in depth, and "carry out urban air prevention and control focusing on the prevention and control of fine particles and ozone pollution".

In the process of industrial development and urbanization, ozone pollution, like smog, has become a big problem that puzzles everyone's life (or survival), but on the other hand, the current ozone control still exists in the primary stage, and we ordinary people still need to wait for a long time to really "fine weather".
