The 'World Trade Center cough' is behind the study.
NEW YORK (AP) -- Nearly 70 percent of the rescue and cleanup workers who toiled in the dust and fumes at ground zero have had trouble breathing, and many will probably be sick for the rest of their lives, doctors said Tuesday in releasing results of the biggest Sept. 11 health study yet.
The Mount Sinai Medical Center study is conclusive proof of a link between recovery work at the World Trade Center ruins and long-term respiratory problems, doctors said.
"There should no longer be any doubt about the health effects of the World Trade Center. Our patients are sick," said Dr. Robin Herbert, co-director of the group that has monitored the health of nearly 16,000 ground zero workers.
Herbert said that most of the patients in the study first came to ground zero between Sept. 11 and Sept. 13, 2001, which exposed them to asbestos, pulverized concrete, mercury and toxins that will leave them chronically sick.
"Our patients were very, very highly exposed, and are likely to suffer health consequences as a result of that for the rest of their lives," she said.
Herbert was joined by lawmakers who accused the federal government of not doing enough to protect the workers' health and not spending enough to treat them.
Mayor Bloomberg doubts it
Mayor Michael Bloomberg cast doubt on the study's claims, saying, "I don't believe that you can say specifically a particular problem came from this particular event."
Dr. John Howard, who was appointed by the Bush administration in February to coordinate the various ground zero health programs, called the findings "extremely important" and said they support other researchers' work, including a study of city firefighters.
The study, to be published Thursday in the journal Environmental Health Perspectives, focused mostly on what has come to be called "World Trade Center cough" in 9,442 ground zero workers examined between July 2002 and April 2004.
They included construction workers, police and firefighters and other volunteers who worked at the site, in the city morgue or at a landfill where more than 1 million tons of trade center debris were carted.
In lung function tests, ground zero workers had abnormalities at a rate double that expected in the general population; these problems persisted for months and in some cases years after the exposure, the study found.
Respiratory problems worsen
The study said that almost 70 percent of trade center responders had new or worsened respiratory problems during or after the attacks. Sixty-one percent of responders who had no health symptoms before the attacks developed problems while working at ground zero. One third of those tested had abnormal lung function, which Herbert said is a rate twice as high as the nonsmoking population.
Ironworker John Sferazo, who spent 30 days on the smoldering debris pile and now takes 26 medications a day to deal with his lung problems, said the White House did too little, too late. "If President Bush wanted this situation to be cleaned up, it would have been cleaned up long before now," he said.
He said he was having trouble getting words out at Tuesday's news conference because he is constantly short of breath and has restrictive airway disease. "I'm lucky if I can run a city block without dropping dead," said Sferazo, 51.
Lawmakers said the government has to develop a coordinated funding program to pay for health care for the workers for the rest of their lives, and said environmental officials failed to warn people about the danger of breathing the air near the site.
"It was obvious that the air was hard to see through, let alone hard to breathe," said Sen. Hillary Rodham Clinton.
