I didn't get the impression that it was said as a negative critique of film, but if you want citations in that direction it's easy. Just look up all the crap the Kodak plant has been found to dump into the water/environment around Rochester. Lots of dioxins, carcinogens, etc. Tons of methylene chloride just to name one example. It's a giant chemical production plant, what do you really expect? GMO kelp and rainbow farts?
