Known thermite / thermate components or residues
Classical thermite residue in iron described by Hans Goldschmidt
1 iron
2 carbon
3 copper
4 silicon
5 manganese
6 aluminum
7 phosphorus
8 sulfur
An [original] thermite reaction as described by his inventor Hans Goldschmidt himself would leave the following residues:
1: 99% iron (elemental), 2: Carbon 0.10%, 3: copper 0.09%, 4: silicon 0.09%, 5: manganese 0.8%, 6: aluminum 0.07%, 7: phosphorus 0.04%, 8: sulfur 0.03%,
1/3 of the residue volume, about half the mass of the original Fe2O3 – Al-compound
The other 2/3 would be Al2O3, Korund, mostly slag, maybe as tiny ash blowing away with a plume of smoke.
Other typically thermite ingredients:
9 potassium
10 vanadium
11 titanium
12 tin
13 Fluorine
14 calcium
15 silicon
16 magnesium
17 sodium
18 oxygen

MeT: When thermite reaction components are used to ignite a fire, they produce a characteristical white-yellow flame in the reaction region, leaving clear evidence. These residues are almost unique in their chemical composition, in which they often contain abundant elements such as 2: copper, 1: iron, 9: potassium, 2: carbon and 6: aluminum, but also less common materials such as 10: vanadium, 11: titanium, 12: tin, 5: manganese, and 13: Fluorine. While some of these residues may be burned by the fires, many stay back as a feedstock.

1: iron, 14: calcium, 9:potassium, 15: silicon, 6: aluminum, 16 magnesium, 17: sodium,
Known thermite residue analysis Truth-Burn- “Burning Man” Spherules ca. 2007
1: Iron, 2: carbon, 18: oxygen, 18: sodium, 17: magnesium, 6: aluminum, 15: silicon, 9: potassium, 14: calcium,
Known thermate formular:
1: iron-oxide, 2 aluminum, bariumnitrate (21 barium, 17 sodium), 8 sulphur, binder BPAT C10H13NO2 (2: carbon, hydrogen, nitric oxide)
Now consider this together with the OSHA studies. I will highlight every known thermite residue with bold letters, and number them:
Metals
OSHA has taken a total of 1331 samples (excluding bulk and blank samples) to monitor worker exposures to dusts, fumes, oxides, and other compounds of metals such as antimony, beryllium, chromium, cobalt, copper, iron, lead, manganese, mercury, molybdenum, nickel, vanadium, zinc, cadmium, magnesium, and arsenic. To minimize the length of the "WTC OSHA Heavy Metal Monitoring Data tables" only the samples that showed detected results for these metals are listed. Results from these samples are generally well below the applicable OSHA limits. However, torch cutting and burning structural steel at the rubble pile have resulted in instances of overexposures as follows: 3: copper (17); 1: iron-oxide (28); lead (19); zinc oxide (1), antimony (1); and cadmium (3).

On german news magazine Telepolis a munich author Michaela Simon reported about a friend in NY, then living in 110 Greenwich St 10006, who documented the cleaning process in the hood after 9/11.
“A resident of 300 Albany Street send the garbage in his apartment [indicated by reporting mail before 2001-10-25] to have it analysed. The samples contained significant amounts of 1: iron, 10: vanadium, nickel, 6: aluminum, 14: calcium, 16: magnesium,17: sodium, chromium, 11: titanium, 5: manganese, 7: phosphorus, 9: potassium, molybdenum, cobalt, beryllium, 3: copper, zinc and arsenic.

EPA stated:
Results as of mid-January, 2002:
EPA detected fourteen metals: antimony, arsenic, cadmium, 5: manganese, nickel, 6: aluminum, 21: barium, 3: copper, 1: iron, 17: magnesium, 18: sodium, 14: calcium, 10: vanadium, and zinc. The first five of these metals are hazardous air pollutants (HAPs), also called toxic air pollutants, under the Clean Air Act. Although we detected these metals, their low concentrations mean they pose no potential for significant risk of long-term health problem s from the WTC cleanup effort.

Experts report other contents in this dust including "microscopic traces of nearly every element - chromium, 16: magnesium, 5: manganese, 6: aluminum, barium, 11: titanium, and lead." [N.Y. Times, "What Happened to That Cloud of Dust", Pg. B1, B7, 11/2/2006].
