air quality standards

The air quality reflects the degree of air pollution, which is judged according to the concentration of pollutants in the air. Air pollution is a complex phenomenon. At a specific time and place, the concentration of air pollutants is affected by many factors. Man-made pollutant emissions from fixed and mobile pollution sources are one of the most important factors affecting air quality, including the tail gas of cars, ships and planes, industrial pollution, heating of residents' lives, garbage incineration and so on.

Urban development density, topography and meteorology are also important factors affecting air quality. In addition, the concentration of "negative oxygen ions" is also one of the signs of air quality. According to the standards of the World Health Organization, when the concentration of negative oxygen ions in the air is higher than per cubic centimeter 1000- 1500, it can be called "fresh air".
