Hello makers!
I was looking for some NO2 rates cause I want to compare levels depending on the cities. I don't know what is the good (low) and bad (high) rates of NO2 in cities. I found information only in this site:

But the avarage rates of Air Quality Egg are in the range of 300-600 ppb. Could anybody help me with this?
