toxic air

The image is striking and points to many scales at which we can think of air quality--personal air quality within an apartment, air quality from outside the building, sources of air pollution within the building. Each of these points to different processes which produce toxic and poor air quality. I would be curious to see how the ethnographer thinks about air quality in relation to these different sources, and what it does for her thinking about the pollution from outdoors (the refinery, vehicular pollution, etc).
