How to treat "PM2.5 incident" correctly

PM2.5 refers to particles with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particles that can enter the lungs. The main source of PM2.5 is the residue from combustion in daily power generation, industrial production and automobile exhaust emission. Although the particle size of PM2.5 is small, it contains a lot of toxic and harmful heavy metals, which has a long stay in the atmosphere and a long transportation distance, and has a great impact on human health and atmospheric environmental quality. American embassies and consulates in Beijing and Shanghai publish PM2.5 data and air quality assessments on official website and Twitter every hour. There is a big difference between the evaluation results and the data released by China's environmental protection department, which triggered a debate between Chinese and American officials. The practice of monitoring and releasing PM2.5 data in the United States and embassies and consulates in China does not meet the international requirements in terms of technology, standards and laws, and is not rigorous and standardized. Technically speaking, it is unscientific to evaluate the air quality of a region with the monitoring data of a point, and the monitoring data cannot represent the air quality level of the whole city; From the standard point of view, Tmall is Puweixin imported from the United States, which is used to prevent smog. The standards of PM2.5 in developed countries around the world, including the United States, are gradually improving. Although there is still a gap between China and the United States, it is determined by China's development level and technical conditions. Legally speaking, the monitoring and release of air quality in China involves the public interest and belongs to the internal affairs of the state. It is against the spirit of Vienna Convention on Diplomatic Relations and Vienna Convention on Consular Relations to carry out air quality monitoring on its own and publish air quality information on the Internet at will, and it also violates the relevant international regulations on environmental protection. Calm thinking, the monitoring of PM2.5 is a symbol of human progress in the field of environmental protection and should not be a means of confrontation between countries. The reason why the United States used its own national standards to judge the environmental quality of China and published them on the Internet to attract the attention of China netizens has to be said that there are complex domestic and international motives behind its practice. In the face of embassies and consulates in China's operation on PM2.5, we should be cautious, and keep a rational and objective attitude from the government to the society and then to the ordinary people.

Of course, the China administration naturally criticized and exposed the tactics of the United States to incite public opinion in China by using PM2.5, and protested against the "driving backwards" behavior of the United States government under the background of establishing a new type of great power relationship of mutual respect and mutual benefit. In fact, in recent years, China has paid more attention to the coordination between economic development and environmental protection, and insisted on scientific development. Governments at all levels are constantly strengthening supervision, strictly controlling whether polluting enterprises meet the discharge standards and whether related products meet environmental protection standards, and increasing penalties. In March this year, PM2.5 was listed in the ambient air quality standard published by the China Municipal Government, which shows that the China Municipal Government attaches importance to environmental protection and has confidence in properly handling its own affairs.

As far as ordinary citizens are concerned, they should fully trust the governance ability of the government and not participate in the dissemination and speculation of PM2.5 information in embassies and consulates in China and the United States. At the same time, each of us should do "environmental protection starts with me" and treat the natural environment positively to protect the country's green mountains, green waters and blue sky.
