New studies shows that a high percentage of cleanup and rescue workers who worked at the World Trade Center following Sept. 11 continue to face physical and health problems. This according to officials at the Mount Sinai Medical Center.

Nearly 50 percent of the workers report they still suffer from problems such as nasal congestion, hoarseness, headaches and throat irritation. Another 30 percent suffer pulmonary problems, including shortness of breath, persistent cough and wheezing. In addition nearly one in five of the workers have been diagnosed with post traumatic stress disorder.
