Which is why these substances are monitored by the EPA, which has identified a risk-free vary for just about every. When any just one of them surpasses their safe range, an air quality warn is induced.
What is an air good quality alert?
The AQI is divided into five groups, primarily based on the amount of pollutants in the air and the corresponding well being danger they pose. As a measurement resource, the AQI spans from to 500. An AQI of 50 and below suggests the air high quality is very good. The AQI increases with the amount of money of air pollution to mirror the increasing wellness threat, initially for choose teams of people, and then for everyone.
