The Nose Knows

Air pollution is invisible, and sometimes that makes it a bit difficult to talk about. Still, we encounter air pollution every day. Sometimes our nose can sniff it out and alert us. In “The Nose Knows,” we explore our region through smells and discuss some tools used to talk about and track those foul odors.

Call to Action: Sign our petition to end illegal violations of the hydrogen sulfide standard in Allegheny County.


Lisa Minetti: Lisa was born and raised in the Pittsburgh area and became active in air quality issues before moving away temporarily to Philadelphia and then New York City. Upon her return, she got swept up in a tirade of continued air quality issues and has once again returned to activism. Read an article she wrote here.

  1. The smell of wood smoke is the most obvious but few people see it as pollution.
