Wow, are you saying thatthey have surveyed dust from similer disasters?
When did that happen?
Oh, yeah, dust from Katrina.
What do you think was in all that black smoke?

Please note the distortion from the cropping of the picture, and also that the contrast has been cranked up for the image.
Here's a link to the original picture (big difference):

So, so sad........
An intriguing photograph (below right) taken by Rob Miller, photojournalist with the New York Post, provides additional photographic evidence (Swanson, 2003) for the use of thermite or a sulfur-containing derivative such as thermate. We see debris and dust as WTC 1 collapses, with WTC 7 seen in the foreground, across the street from WTC 1.
469x383 pixels.
What if some really wicked mind would have used a thermite mix of iron oxide and depleted uranium, which could reach a max temperature of 4131°C, 7468°F , the boiling point of Uranium? And ignited the thermite mix with a sparkler.
Since we still have this explanatory problem with all that molten steel found in the deepest basements reported by several trustable sources.
We see the grave implications if we, or a serious neutral private investigation with access to everything they ask for, not blocked by blockheads in an evil administration, and backed by a reformed Congress and House, would come up with definite proof for even the most dickheaded "official theory" believer, that this administration was complient, or even planned 9/11.
The result COULD be a bloody civil war, with most of the US forces abroad, with a lot of their heavy equipment.
Can you imagine who would jump on the occasion?
That's why you have to be extremely carefull how to bring forward any solid proof, do it bit by bit, or all hell will break loose.
Leave enough room to let the greedy politicians revoke their decades long attitude, and step into the plate, to start a hard needed reform on all levels.
And I do care to much for all these fine and normal americans I know personnally and online, to set the stage for a bloody outbreak of violence.
Note: think about it: you own a Conspiracy site.
You see the postings go down, and the quality thereof.
You create your own team of intelligent opponents.
Ratings and postings rocketing to the sky again......Good idea, all benefit.
Just a thought.
If you convert the 2 charts of WTC 1 and 2 to the same sensitivity of 0-10 nm/s, instead of the offered by LDEO sensitivity of 10-100 nm/s, you will see that suddenly these 2 charts have collapse-preceeding peaks exactly as high as in the WTC 7 (0-10 nm/s) chart. And all three of them are identical, meaning they used the same type and power of charges for the first hard blow to all three structures.
"Then it's crystal clear that 3 identical heavy explosions preluded all 3 collapses.
Explosions which were comparable to the two plane impacts on 9/11, just compare the first two original LDEO 0-10 nm/s (plane impact) seismic charts, with the Long Lance 10x seismic charts of the WTC 1 and 2 collapses and the LDEO WTC 7 colapse original seismic chart.

""Pyrolysis of DPP at 375 °C in the gas phase (7) or attached to the surface of Cabosil (8) occurs by a free-radical chain reaction to produce toluene and styrene as the major products.""
(7) M. L. Poutsma and C. W. Dyer, J. Org. Chem., 1982, 47, 4903; K. E.
Gilbert and J. J. Gajewski, J. Org. Chem., 1982, 47, 4899.

Org. Chem., 1989, 54, 517.
It means that DPP as a gas which is burning, emanates toluene and styrene.
Not the other way round.
Which is a moot argument btw, since it was not DPP which was reported, but a much more complex derivative of it.

I should have said Polystyrene, not styrene. My bad.
Pyrolysis of polystyrene will produce diphenylpropane.

And you are right; it is a moot point since that is not the compound detected in the air samples.
Quote 1:
On pyrolysis, depolymerization of the polystyrene occurs and the product is styrene.
Quote 2:
Figs. 4 and 5 show characteristic pyrolysis products from the thermal degradation of two ternary mixtures—a mixture of poly(vinyl chloride), polystyrene and polyethylene (1:6:3 by weight, mixture 1) and a mixture of polystyrene, polyamide 6 and polyethylene (3:1:1 by weight, mixture 2). The obtained products differ significantly in both cases.
-snip-
Different products are obtained during the thermal degradation of mixture 2,
compare Fig. 5. The conversion of polyamide 6 into e-caprolactame is about 95%
resulting in an amount of 18% by volume e-caprolactame in the pyrolysis gases.
The amount of e-caprolactame is consistent with the available amount of
polyamide 6 in the mixture and a residence time of 26 min. The yield of styrene is
about 38% by volume in the pyrolysis gases whereas only a small amount of
ethylbenzene is formed. The amount of styrene dimer increases up to 25% by
volume and the amount of styrene trimer up to 15% by volume. Apart from that,
1,3-diphenylpropane occurs with an amount of 10% by volume.
The yield of styrene decreases when polyamide 6 is present in the mixture. In this
case a larger yield of styrene dimer and trimer is obtained.
And you are right; it is a moot point since that is not the compound detected in the air samples.
