For the first time a study has linked lung disease found in 9-11 rescue workers to the dust from the World Trade Center buildings. The rate of sarcoidosis in 9-11 rescuers after the World Trade Center disaster was 5 times higher than the rate of the disease in the 15 years before the disaster. The disease can produce inflamation in the lungs which breeds lumps of cells called granulomas.
So sarcoidosis has been identified as one of the diseases workers contracted from breathing Trade Center dust. Hopefully there will be further studies to determine what other diseases these workers have contracted from the World Trade Center dust.
