A new book by Phaedra C. Pezzullo from the University of Alabama Press is the first (that I'm aware of) scholarly book on the subject
Using guided tours as a form of organizing and educating like this is a tactic somewhat widely explored, so I thought I'd post a few examples that include artists and activists' work.
- Sharon Stewart's early 1990s "Toxic Tour of Texas" is probably the first I became aware of.
- Free Soil's "Gardening Superfund Sites Bus Tour"
- Invisible 5 audio tour of California's I-5 Highway
- Silicon Valley Toxics Coalition Toxic Tour
- Ground Work's (South Africa) Household Toxic Tour
- Baltimore Toxic Tour on Youtube
- The Southern California Communities for a Better Environment's Toxic Tours
- Toxic Tourism in Tucson (an article that includes comments by noted Environmental Justice scholar Robert Bullard)
- in San Francisco
Obviously there are more...
