away from established federal agencies, such as the Federal Emergency Management Agency, the U.S. Army Corps of Engineers and the Occupational Safety and Health Administration. He instead handed over responsibility to the "largely unknown" city Department of Design and Construction. Documents indicate that the Giuliani administration never enforced federal requirements requiring the wearing of respirators. Concurrently, the administration threatened companies with dismissal if cleanup work slowed. Workers at the Ground Zero pit worked without proper respirators. They wore painters' masks or no facial covering. Specialists claim that the only effective protection against toxins, such as airborne asbestos, is a special respirator. New York Committee for Occupational Safety and Health industrial hygienist David Newman said, "I was down there watching people working without respirators." He continued, "Others took off their respirators to eat. It was a surreal, ridiculous, unacceptable situation." The local EPA office sidelined the regional EPA office. Dr. Cate Jenkins, a whistle-blower EPA scientist, said that on September 12, 2001, a regional EPA office offered to dispatch 30 to 40 electron microscopes to the WTC pit to test bulk dust samples for the presence of asbestos fibers. Instead, the local office chose the less effective polarized light microscopy testing method. Dr. Jenkins alleged that the local office refused, and said, "We don't want you fucking cowboys here. The best thing they could do is reassign you to Alaska." Health effects There were many health problems caused by the toxins. 99% of exposed firefighters reported at least one new respiratory problem while working at the World Trade Center site that they had not experienced before. Chronic airway disease is the main lung injury among firefighters who were exposed to toxins during 9/11. Six years after the attacks, among those who never smoked, approximately 13% of firefighters and 22% of EMS had lungs that did not function as well as others around the same age. Steep declines in pulmonary lung function has been a problem since first detected among firefighters and EMS within a year of 9/11 have persisted. Increasing numbers of Ground Zero workers are getting illnesses, such as cancer. Between September 11, 2001, through 2008, there were 263 new cases of cancer found in 8,927 male firefighters who responded to 9/11 attacks. This number is 25 more than what is expected from men from a similar age group and race. There is a 19% increase in cancer overall, between
