Dust, published in 2009, is a book by Paul Lioy, an environmental scientist who was part of a group of scientists that sampled and analyzed the dust at the World Trade Center site after the September 11, 2001, terrorist attacks, focusing on the composition of the toxic materials in the dust. In the book, Lioy discusses what was in the dust, including how factors such as particle size, especially during the actual collapse and shortly after, affected the rescue workers.
The hardcover version of the book is around 250 pages. The book is informative, but it is not the easiest read. The better the knowledge of chemistry you have, the easier the book is to understand. While Lioy does write it in such a way that it can be understood even if you do not have a chemistry or chemical engineering degree, it is the cross between a news article intended for mass consumption and a peer-reviewed journal article. It does contain some interesting information, such as how the composition and particle size of the dust changed over various time periods, and why the amount of asbestos in the dust was not as significant an issue as some thought, as well as why they did not test for the presence of DNA in the dust.
The book does not focus on the actual 9/11 attacks. The discussion on the actual events amounts to a couple of paragraphs at most. So, if that is what you are most interested in, this book may not be for you. But, if you have followed the issues with the illnesses that people who worked at the Trade Center site have experienced, this is worth reading.
