The largest health study yet of the thousands of workers who labored at ground zero shows that the impact of the rescue and recovery effort on their health has been more widespread and persistent than previously thought, and is likely to linger far into the future.

The study, released yesterday by doctors at Mount Sinai Medical Center, is expected to erase any lingering doubts about the connection between dust from the trade center and numerous diseases that the workers have reported suffering. It is also expected to increase pressure on the federal government to provide health care for sick workers who do not have health insurance.

Roughly 70 percent of nearly 10,000 workers tested at Mount Sinai from 2002 to 2004 reported that they had new or substantially worsened respiratory problems while or after working at ground zero.

The rate is similar to that found among a smaller sample of 1,100 such workers released by Mount Sinai in 2004, but the scale of the current study gives it far more weight; it also indicates significant problems not reflected in the original study.

For example, one-third of the patients in the new study showed diminished lung capacity in tests designed to measure the amount of air a person can exhale. Among nonsmokers, 28 percent were found to have some breathing impairment, more than double the rate for nonsmokers in the general population.
