How does Weather Link query the air pollution index?

You can see it with the "Ink Weather" software. You can read this article about how to divide degrees:

At present, the air pollution index adopted in China is compared with the national air quality standard through the measured pollutant content. When it is just equal to the secondary standard, its index is set as 100, and the higher the pollutant content, the greater the index. Generally defined, the index is 0-50, the air quality is described as excellent, 5 1- 100 is good,1-150 is light pollution,151.

The prediction of air pollution index can remind the public, especially those who are sensitive to air pollution, such as those with heart disease or respiratory diseases, to take preventive measures when necessary before serious air pollution occurs.

Influence of air pollution index, air quality level and air quality on human health

0-50 grade I is excellent. At this time, there is no air pollution problem and there is no harm to public health.

5 1 100 I is good. At this time, the air quality is considered acceptable, and there is no harm to public health except that a few people are particularly sensitive to certain pollutants.

10 1- 150 ii( 1))。 At this time, people who are sensitive to pollutants, such as children and the elderly, patients with respiratory diseases or heart diseases, and people who like outdoor activities, will have an impact on their health, but basically have no impact on healthy people.

15 1-200II (2)) light pollution.

20 1-300IV (1)) and IV2)) Moderate and moderately severe pollution At this time, almost everyone's health will be affected, especially sensitive people.

At this time, everyone's health will be seriously affected.
