According to preliminary findings from the World Trade Center Health Registry, people who were near the WTC on September 11 or worked in the recovery effort have had respiratory and/or psychological problems. Yes, it's no huge surprise considering what happened (the city's two tallest buildings, two commercial airplanes, thousands of people), but the NYC Department of Health calls the findings confirmation that "tens of thousands of registry enrollees reported significant respiratory and mental health symptoms." The WTC Registry hopes to monitor people for the next 20 years, as well as use the information to treat victims of other incidents (like large fires or accidents).
