There will be contiguous ozone pollution in Sichuan, which provinces and cities will be affected?

? There may be contiguous ozone pollution in Sichuan, and Chengdu, Zigong, Luzhou, Deyang, Mianyang, Suining, Neijiang, Leshan, Nanchong, Yibin, Guang 'an, Dazhou, Meishan and Ziyang may be affected by this ozone pollution.

? Hazards of ozone pollution: ozone has a strong oxidizing property, so it has a strong bactericidal effect. Besides killing the propagule, it can also achieve the purpose of deodorization. However, the strong oxidation of ozone will do harm to human health. Inhaling a lot of ozone can cause cell damage and even cancer. There are many hazards of ozone, which can lead to vision loss, nerve poisoning, dizziness and headache, and memory loss. Ozone can lead to skin deterioration, wrinkles and dark spots, because it destroys vitamin E in the human body. Ozone can also destroy the immune function of human body, induce lymphocyte chromosome lesions, accelerate aging, and make pregnant women give birth to deformed children. When the human body inhales too much ozone, it strongly stimulates the human respiratory tract, causing sore throat, chest tightness and cough, causing bronchitis and emphysema.

Causes of ozone formation:

Ozone is mainly produced by nitrogen oxides and volatile organic compounds? Precursors formed by chemical reactions in the atmosphere, especially in high temperature environment in summer. Among them, nitrogen oxides mainly come from the combustion of fossil fuels and automobile exhaust emissions. The volatile organic compounds mainly come from the exhaust emissions of dry cleaning, organic chemical industry, surface painting and other industries and the volatilization of oil and gas in gas stations. ?

Ozone is mainly gaseous, so wearing a mask can't effectively protect it. The best way is to avoid contact. People should stay away from roadside, decoration and other places with serious pollution. When the sun is strong, sensitive people such as children and the elderly should try not to go out in the sun. Priority should be given to the development of products and services that emit less volatile organic pollutants, such as water-based coatings, conventional gas stations and natural gas stations. Natural gas recovery facilities and vehicles have no gasoline smell when refueling, which can provide strong support for ozone pollution prevention and control.
