Air quality is unhealthy, #CodeOrange today. Mon Valley residents – aka those with respiratory diseases, elderly and children take care outside (with the freezing temps). Thank you @alleghenyhealth for activating Everbridge the alert to the public! #SmellPGH #airquality

‼️#Stinkburgh Alert! Strong inversion predicted for tomorrow morning in Pittsburgh. Looks like it might get worse over the weekend. Submit #SmellPGH complaints and @HealthAllegheny complaints as you encounter stench! @GASPPgh @BreatheProject @cmucreatelab

SmellPGH app screen shot showing triangles where people have reported smells in Allegheny County. Air quality monitors show air from green to yellow to red in the region.

#Stinkburgh Alert! Polluted/smelly air today in Pittsburgh. More likely this week. Watch out for some light impact of wildfire smoke from Canada on our regional air quality this week, though only time (and wind) will tell if we get hit worse in the coming weeks. #SmellPGH

Really fun feeling when my air purifier suddenly ramps up to high gear and then my throat starts hurting. I thought I left that behind in the realm of the #ClairtonCokeWorks and the #SmellPGH app…
