If American standards do not reflect the air quality of Beijing, it is obviously not convincing. The standard is the United States. It is measuring the air in Beijing. The so-called American standards do not reflect the theory of air quality in Beijing.
This can only show that it is not citizens who feel that air pollution is serious, but that the current national standard is too “understatementâ€. Obviously, if the number of suspended particles with a diameter of less than 2.5 microns is not monitored and published, the air pollution level will obviously be greatly reduced, and “heavy pollution†may become “mild pollutionâ€, and the good weather will be many and numerous each year. There will be less and less bad weather. Or it may become a political achievement in managing environmental air pollution.
When will our air quality standards meet international standards?
