From the Associated Press:

"James Zadroga spent 16 hours a day toiling in the World Trade Center ruins for a month, breathing in debris-choked air. Timothy Keller said he coughed up bits of gravel from his lungs after the towers fell on Sept. 11, 2001. Felix Hernandez spent days at the site helping to search for victims. All three men died in the past seven months of what their families and colleagues say were persistent respiratory illnesses directly caused by their work at ground zero."

Then there's this from Common Dreams:
"A week after the attack, the EPA announced that the air near ground zero was safe to breathe, but the agency did not have enough information to make such a guarantee, the inspector general's report said.
"Christie Whitman was too premature to say it was safe," Cahill said Tuesday. "I think the EPA should have known. The EPA had its own reports saying it could be dangerous. Why didn't the EPA bring in their own people from all over the country? They could have. Never thought of it. They did later. But not in the time that mattered."
WHITE HOUSE PRESSURE
The White House "convinced EPA to add reassuring statements and delete cautionary ones" by having the National Security Council control EPA communications, the inspector general's report found."
