Ozone pollution may occur in Sichuan 14 cities. What is the cause of ozone pollution?

Since 20 18, China's environmental protection issues have been put on the agenda, and relevant departments have put forward many requirements for specific measures of environmental protection, and even issued many relevant policies. In recent years, the environmental quality of China has really improved greatly. Compared with previous years, the air quality is obviously better, and many blue sky and white clouds appear more and more frequently, which is not only helpful for the people to keep happy, but also of great significance to the health of the general public.

However, on April 27 this year, CCTV reporters learned from the Sichuan Provincial Department of Ecology and Environment that from April 29 to May 3, ozone pollution may occur in Sichuan, and Chengdu, Zigong, Deyang, Mianyang, Leshan, Yibin and other cities 14 may be affected by this ozone pollution. So what exactly is ozone pollution? In fact, ozone pollution is essentially photochemical smog. Photochemical smog is the gas with pollutants discharged into the atmosphere during the operation of pollution sources such as automobiles and factories, which generates photochemical reactions under the action of sunlight and forms harmful smog with certain colors. This kind of smog not only has a very serious impact on the health of animals and plants, but also has a local corrosion effect on the materials of buildings, and will greatly reduce the visibility and affect the travel problems of local citizens.

So many netizens will ask: What is the cause of ozone pollution today when environmental governance is so strict? According to the notice issued by the office of the leading group of the local provincial pollution prevention and control station, the superimposed pollution of PM 2.5 is most likely caused by the centralized burning of straw in some cities in southern Sichuan and eastern Sichuan of Chengdu Plain. At present, the relevant departments of Sichuan Province have issued an early warning to the citizens in this 14 urban area to remind citizens and friends to pay attention to protection when traveling. Relevant enterprises are also required to discharge industrial waste in strict accordance with laws and regulations during the production process, and it is strictly forbidden to directly discharge unqualified sewage, gas and dirt into the natural environment; For grass-roots power grid personnel and business leaders, we will also strengthen environmental protection knowledge training, accelerate the development of major industrial industries to low pollution, low energy consumption and high environmental protection, and strictly investigate and deal with enterprises that fail to meet the standards for discharge and rectification; And increase the exposure of typical illegal cases to deter these enterprises, and also ensure that other enterprises will not cause further pollution to the environment and ensure the continuous improvement of air quality in the province.

Faced with this situation, we netizens should also take a warning, try to reduce driving trips in our daily lives, reduce the burning of some garbage and waste, and make contributions to our beautiful environment. ?
