Healthy/Unhealthy levels

[A Former User]

Where can I find tables to describe healthy and unhealthy levels of air particulate according to what is available on this app, that is, when it comes to different particulates that are selectable here, where can I go to find out if those particulates are at a healthy or unhealthy level?
