Make sure you take a close look at the maps of sampling locations, the tables with more detailed results, and take note of the calendar dates when the sampling was done. I also recommend looking up the references provided by Jenkins.
C7, please acknowledge that you now know that WTC dust immediately after 9/11 did NOT contain even nearly 6% iron, that the mean is consistently close to 1% in several studies, that not even a single sample at a single location came near 6%, and that therefor the RJ Lee value of 5.87% is an extreme outlier and not explainable by a large amount of thermite in the towers. And that you now consider the possibilities that this outlier could be an error, or not mean what you think i means, or can be best explained be the deposition of additional iron durng the 9 months after the collapse dust had settled on 9/11.
Later in the paper, he works with additional data about airborne iron (aerosols) measured in the months after 9/11. Using his references, I found a database of the EPA data and downloaded the measurements at a location on Liberty Street; from that raw data is my value for aberage iron content of air on Liberty which may have precipitated into RJ Lee's dust.

Remember I did the work and showd my assumptions? Do you remember that you did not refute a single of my assumptions, and corrected none of my work?
If you read the RJ Lee report in context, you will find that this Table 3, that reports 5.87% iron spheres, refers not to inaccessible locations in the Building, but to accessible surfaces in the open Gash in the front of the building.
