Gefährlicher Luftverschmutzungsgrad in der Zavaryan St

I was looking at the map and noticed Shengavit had the highest pollution, with the wind direction blowing up towards the center and reaching Komidas, with center pollution being slightly below Shengavit, and Komidas even further below. Which made me question if Shengavit is the center of pm2.5 pollution? is there some fabrication there? I know that there are many houses there, and I assume many of those burn wood. Just a theory.
