The Habitable Planet
Atmospheric Pollution (#111)
Once released, air pollutants react chemically with each other under solar radiation to become even more dangerous secondary pollutants. A company in the Northeast U.S. tracks the emission of pollutants at street level, while an international long-term study follows plumes of pollution from Mexico City across the continent and beyond.
