A federal screening program that tested workers at ground zero for health problems 10 to 11 months after the terrorist attacks found people still showed lung, throat, or mental ailments, according to a study's preliminary findings.
The program found that 52 percent of workers suffered from ear, nose, and throat ailments, 46 percent showed pulmonary symptoms, and 52 percent reported such mental health problems as post-traumatic stress disorder as a result of their work in the WTC rubble.
