Paul Lioy, Scientist Who Analyzed 9/11 Dust and Its Health Effects, Dies at 68 — NYTimes.com

— From NY Times, July 11, 2015

Paul J. Lioy, an environmental scientist widely known for his analysis of the dust spawned by the Sept. 11 attacks on the World Trade Center and for his studies of its health effects over time, died on Wednesday after collapsing at Newark Liberty International Airport. He was 68.

The cause had not been determined, his wife, Jean Lioy, said.

Dr. Lioy (pronounced LEE-oy) was an internationally renowned authority on exposure science, a field concerned chiefly with pollutants and toxins that straddles environmental science and occupational health. He was the author of “Dust: The Inside Story of Its Role in the September 11th Aftermath,” a book for a general readership published in 2010.

At his death he was a professor of environmental and occupational health of the Rutgers University School of Public Health, in Piscataway, N.J., as well as the department’s deputy director for government relations.

From his home in Cranford, N.J., Dr. Lioy could see the plumes of dust that rose from the ruins of the trade center towers on Sept. 11, 2001. A million tons of dust would rain down on Lower Manhattan.

Once his initial horror at the spectacle subsided, the scientist in him began to wonder just what was in that dust.

“It was unprecedented in terms of the complex characteristics of the materials released,” Dr. Lioy told The Asbury Park Press in 2011.
