Visualizing Air Pollution Along the Mississippi River

A map showing that there are more than 200 high polluting plants between East Baton Rouge and New Orleans.

ProPublica has created a series of data visualizations showing the high levels of air pollution that exist on an industrial stretch of the Mississippi River between Baton Rouge and New Orleans. The visualizations show that this stretch of Lousiana, which takes roughly 90 minutes to drive through, has more than 200 plants emitting toxic chemicals at high enough levels that the plants must report the emissions to the government. ProPublica estimates that the air in St. Gabriel, a city in one of the seven parishes, is more toxic than the air in 99 percent of the United States. 

Take a look.
