Scientist who studied 9/11 dust dies


Paul James Lioy, an environmental scientist recognized for his evaluation of the well being results of the dust produced by the Sept. 11 terrorist assaults on the World Trade Center, died this week after collapsing at Newark Liberty International Airport. He was 68.

The reason for loss of life has not been decided, his spouse Jean Lioy advised the New York Times.

The creator of the 2010 printed e book “Dust: The Inside Story of Its Role in the September 11th Aftermath,” Lioy obtained two lifetime achievement awards — the Wesolowski Award from the International Society of Exposure Analysis and the Frank Chambers Award from the Air and Waste Management Association.

Lioy was a professor of environmental and occupational well being on the Rutgers University School of Public Health, the place he specialised in publicity science, in accordance with the college’s web site.

He was additionally the deputy director for presidency relations for the Public Health division at Rutgers University.

In this discipline, Lioy specialised with the toxins and pollution that have an effect on each environmental science and occupation well being.

After witnessing the dust rising from the ruins of the Twin Towers all the way in which from his residence in Cranford, New Jersey, Lioy turned one of many first scientists to assemble samples and check the dust from the positioning.

“It was unprecedented in terms of the complex characteristics of the materials released,” Lioy advised USA Today in 2011.

In an interview on the Rutgers web site, Lioy defined his findings: the dust was linked to an array of long-term well being issues, most alarming an surprising persistent cough skilled by some cops, residents and firefighters.

“In the first 48 hours, the government was concerned about asbestos being the primary threat,” Lioy mentioned. “But it was not. Asbestos exposure is a long-term problem. Once the ‘World Trade Center cough’ started appearing, we realized it wasn’t caused by asbestos.”

According to Lioy, three components induced the cough.

“First, cement dust was very alkaline — the pH was above 10,” he mentioned. “That irritated the linings of the lungs. Second, glass fibers got stuck in people’s upper airways, like wooden logs in a narrow stream. That trapped the cement particles and enhanced the irritation. And there were very coarse particles that comprised the vast quantity of the dust mass.”

Lioy was born on May 27, 1947, in Passaic, New Jersey. He obtained a B.A. from Montclair State College in physics and schooling, an M.S. from Auburn University in Alabama in physics and utilized arithmetic and a doctoral diploma from Rutgers University in environmental science.

He is survived by his spouse, Jean, whom he married in 1971; his son, Jason; his mom, additionally Jean Lioy; his sister, Mary jean Giannini and his two grandchildren.
