? Sichuan may have contiguous ozone pollution, 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 strong oxidizing properties, so it has a strong bactericidal effect. In addition to killing the reproduction body, it can also achieve the purpose of deodorization. But the strong oxidizing property of ozone will cause harm to human health. Ozone can cause cell damage and even cancer when inhaled in large quantities. Ozone has many hazards and can cause vision loss, neurotoxicity, dizziness, headaches and memory loss. Ozone will lead to the deterioration of human skin, wrinkles, black spots, because it destroys the human body's vitamin E. Ozone will also destroy the body's immune function, inducing chromosomal changes in lymphocytes, accelerating the aging process, causing pregnant women to give birth to deformed babies. When the human body inhales too much ozone, it strongly stimulates the human respiratory tract, causing sore throat, chest tightness and coughing, triggering bronchitis and emphysema.

Causes of ozone formation:

Ozone is mainly formed by nitrogen oxides and volatile organic compounds. precursors? which are formed by chemical reactions in the atmosphere, especially in hot summer conditions. Among them, nitrogen oxides mainly come from the combustion of fossil fuels, automobile exhaust emissions, etc., and volatile organic compounds mainly come from the emissions of exhaust gases from industries such as dry cleaning, organic chemicals, and surface coating, and the volatilization of oil and gas from gas stations.?

Ozone is mainly gaseous, wearing a mask can not effectively protect, the best way to avoid contact. People should stay away from roadsides, renovations and other heavily polluted places. Sunlight is very strong when children, the elderly and other sensitive groups, try not to go out in the sun. Priority should be given to the development of products and services that emit fewer volatile organic pollutants, such as water-based paints, regular oil filling stations and natural gas filling stations. Natural gas recovery facilities and vehicle refueling without gasoline odor can provide strong support for ozone pollution prevention and control.
