Until now, dust collected from near Ground Zero after the 9/11 attacks has been considered to be a single type of dust. This has been a reasonable assumption, given that the largest proportion of the dust has a light gray appearance. This report shows that there are actually several different types of dust (Fig. 6C), each containing a different proportion of fibers, crystals, chips and microspheres. Until now, the heterogeneity of the dust has not been adequately explained. No one has reported a specific examination of the different types of dust, and no one has related these images to the large scale images seen during the destruction of the WTC. What is clear is that the buildings produced distinct types of dust and fumes and that these materials came from different parts of the buildings that were constructed from different materials.

The advanced weaponry used on 9/11 fragmented steel into tiny chips and microspheres, crushed ceramics into finely grained white crystals, turned glass (or possibly paper) into short, straight fibers and nearly atomized aluminum into tiny droplets. During the moments of destruction, the overall structure of these materials was that of foam, a sort of sizzling, liquid building cascading down to the ground and covering lower Manhattan and rising into the sky. The process achieved this without excess heat and resulted in years of fuming and a distinct smell that was widely reported as “The WTC Stench”.

This paper gives the first explanation of the following image taken of a steel beam recovered from Ground Zero (Fig. 6D). This image depicts each major type of dust studied in this paper, the dark gray, lighter gray and rusty colored dust. Furthermore, it is obvious that the beam has increased in volume but decreased in material strength, as it has folded upon itself. Dark and lighter colored dust is seen (but not explained) in many images of the aftermath in NYC and in televised reports (Fig. 6C, 7A). Amazing images exist of the cleanup efforts at Ground Zero which also depict the dark and light dust (Fig. 7B-C). These images, taken after WTC 7 had been rebuilt in 2006, show the attempts of the cleanup workers to blast away the multiple colored dusty foam that was found in great abundance in the basement of the WTC.
