Many workers who worked in the World Trade Center after the September
eleventh attacks became sick. They breathed a mix of dust, smoke and chemicals
in the ruins of the Twin Towers and a third building that fell. Some went clays
without good protection for their lungs. Five years later, many of the thousands
who worked at Ground Zero in the early days after the attacks still have health
problems. Doctors at Mount Sinai Medical Center in New York City have announced
the results of the largest study of these workers. The study confirmed high
rates of breathing problems in members of the building trades, firefighters,
police officers and other workers. Almost seventy percent of the workers in the
study had a new or worsened breathing problem. These problems developed during
or after their time working in the mountain of wreckage. About sixty percent
still had breathing problems at the time of their examination. The researchers
say they decided to study the effects on breathing first because other disorders
might be slower to appear. Mount Sinai says it tested almost twelve thousand
people between two thousand two and two thousand four. Eight out of ten of them
agreed to have their results used in the report. The new results added strength
to a Mount Sinai study released in two thousand four. That study was based on
only about one thousand workers. Some lawmakers have sharply criticized city and
state officials for letting workers labor at Ground Zero without satisfactory
equipment. Officials have also been criticized for saying the air was relatively
safe. State and federal officials have promised more than fifty million dollars
to pay for treatment of the workers. Doctor Robin Herbert is one of the
directors of the Mount Sinai testing program. She says people are still coming
to the hospital for treatment of problems that were caused by the dust at Ground
Zero. In her words:" My worry is that money will be gone in a year, and what
happens then?"
