It seems like a hundred years ago but for many who were there it's still a fresh memory with accompanying health problems and nightmares. So many of the firefighters and police officers who didn't die from the attack died later from the effects of breathing dust made up of concrete, asbestos, mercury, diesel fuel, jet fuel and a host of other nasty things. Those exposed have a four times higher rate of upper respiratory and pulmonary problems than the general public. PTSD has been put at 10,000. Mt Sinai has an entire department dedicated to monitoring and treating those exposed. Anyone who worked at site can sign up to be monitored for present and future health effects
Nothing can bring back the lost lives of the office workers, firefighters and police officers, but we can do our best to take care of the living. If you were there as a worker at the site I encourage you to follow the links and sign up for medical monitoring. The importance being getting treatment and the information is helpful in developing treatments for others.
