In this week’s episode, host Daniel Raimi talks with Nikos Zirogiannis, an assistant professor at Indiana University, about excess emissions of air pollutants—emissions that exceed the legal limits. Zirogiannis discusses some potential causes of excess emissions, the health effects of excess emissions, and the gaps in policy and data that could be addressed to help prevent these dangerous events.
