WTC Dust

Dust:  The inside story of its role in the
September 11th aftermath by Paul J. Lioy

In the chaos immediately following the collapse of the towers, everyone was aware of the dust covering the area around Ground Zero.  But what was the dust?  Environmental scientist Paul J. Lioy samples and analyzes the composition of WTC dust in the days immediately following and in subsequent years.  In Dust he details particle size and organic and inorganic make-up of the dust.  EPA clean up of commercial and residential buildings is discussed as well as the health effects of ingestion of WTC dust.  Some of the chemical analyses was too detailed for me to casually understand, although the overall topic of the book was interesting for its unique look at a part of 9/11 history.
