I know fire fighters are exposed to many toxic substances. There are many more occupations along with every military organization that are also exposed to same or similar toxins. I just dislike one occupation being set out as the only one to these exposures. There were many people exposed to Manhattan's 9/11 incident besides first responders. Anyone living in the vicinity of the Towers were exposed to the same smoldering, blowing debris. I am sure someone was monitoring exposure rates at that time. It would not benefit everyone to limit exposures to just firemen. Sorry my feelings.
