Oh, Lord, not the infamous "
Environmental Anomalies at the World Trade Center" abomination that Kevin Ryan and Steven Jones paid to have published.
First of all, what GIE quoted out of that paper doesn't rebut what I said. For starters, let me remind everyone that Swartz's comment was about the 1,3-DPP level increase
over background. The Ryan, Jones, Gourley paper lies about it. It states the truth, but then turns around and lies about it. Read the relevant section:
Ryan said:
The fact that this species had never been found before is a startling fact, considering that EPA has monitored extreme structure fires before, including those in which polyvinyl chloride (PVC) materials were present.
... Again, the EPA work they quote says:
This species has not previously been reported from ambient sampling.
"Ambient". I.e. "background". The significance of 1,3-DPP levels is it's presence compared to situations where large towers do
not collapse and burn. Yet, right after they quote the relevant EPA piece directly, they turn around and say:
The fact that this species had never been found before is a startling fact, considering that EPA has monitored extreme structure fires before, including those in which polyvinyl chloride (PVC) materials were present.
They clearly indicated that the significance of the 1,3-DPP presence was in comparison to
background levels, not in comparison to other structure fires. The phrase "... EPA has monitored extreme structure fires before" has nothing to do with "The fact that this species had never been found before". There is
no - repeat,
zero - substantiation of any claim that chemical surveys of previous fires showed little to no 1,3-DPP. Rather, they're taking the Swartz statement and twisting it. The dishonesty in the Ryan/Jones/Gourley paper is rank and offensive. It's an attempt to pull the wool over people's eyes, and it's insulting to see it attempted. Which is why it's sad to see people fall for it, like GIE here.
But is it true that, as the paper asserts:
"EPA officials and fire-fighting experts were well aware, from previous studies of a handful of spectacular and tragic fires in hotels, commercial buildings and downtown areas, that such blazes are capable of releasing a witch’s brew of some of the most toxic substances known—including mercury, benzene, lead, chlorinated hydrocarbons and dioxins..."
Yes. It is true. In fact, I discuss a specific instance of that specific issue
here. But where in either the info I posted, or the original source for the above quote does it say that any VOC levels, let alone 1,3-DPP ones, were openly measured in previous fires? Where is the quantitative data that buttresses the claim that 1,3-DPP is missing in other fires? That's not found in the source for that quote, you know. Follow the link; it's not to a report, nor a press release from the EPA, nor any sort of scientific journal; it's from Alternet, and is an activist article criticizing the government response to pollution issues associated with 9/11. The charge about "EPA officials and fire-fighting experts" knowing what substances come out of a fire is actually a
qualitative statement that they're aware of VOC's and other toxic compounds; it is far,
far from being a
quantitative statement saying that "X" levels of a certain VOC exists in standard structure fires, therefore the level in situation "Y" is significant. It certainly cannot be used to buttress the baldface lie that 1,3-DPP does not exist or exists in far smaller concentrations in other office fires.
Man, I'm tired of this. The Ryan/Jones/Gourley paper was already discussed and refuted here:

And because the beginning of the thread has a distracting level of argumentation and personality oriented responses, let me point out a pair of very on-point posts:

And let's re-bury the idiocy that is the Ryan/Jones/Gourley paper. It tries to resurrect a dead thesis with some novel applications of quote-mining, and keeps people on their toes by it's approach with discussions of volatile organic compounds, but ultimately it doesn't overcome the problems inherent in the thermite fantasy. We can all go on and on about how irrelevant the fantasy movement's deathgrip on 1,3-DPP is, but the overall point has always been that thermite is grossly contradicted, and any argument of minituae such as 1,3-DPP is irrelevant in the looming face of no overt signs of thermite use. Just read the thread above, and try your best to get past the bickering posts, because there's real substance there in between the personality conflicts.
