1720 9-11 Firefighters have lung problems

Doctors have been monitoring 13,234 rescue workers from the New York City Fire Department. Of those, specialists have evaluated 13 percent -- 1,720 -- because they've showed signs of lung problems.
...
Between 20 percent and 25 percent of the 1,720 rescue workers have developed "really significant asthma," Weiden said

What was in that dust that has made so many sick?

One thing I found;

How dangerous was the dust released by the World Trade Center collapse? So far scientists disagree, and more research on the health effects is planned.
...
Cahill's main worry is "ultra fine silica" – or vaporized glass and dirt – which the DELTA group found in high concentrations. Unfortunately, he said, the heatlh effects of aerosolized silica have received little study.

Well, that's not true.

OSHA is also preparing to propose a standard
governing occupational exposure to respirable silica. Inhalation of
this substance, which is extremely widespread, causes lung disease,
silicosis and lung cancer.

What's really interesting, and disturbing, is this

In energetic nanocrystalline composites, the energetic material is grown within the pores of an inert gel rather than mixed into it.
...
The Livermore team synthesized nanocrystalline composites in a silica matrix with pores containing the high explosive RDX or PETN. The resulting structures contain crystals so small that they do not scatter visible light and are semitransparent.

Explosives embedded in glass?? Something stinks.

Hmm...so the proof of explosives used during 9/11 is in the rescue worker's lungs!

One advantage of silicon explosives over conventional explosives, which must be ignited by mechanical means, is that they can be ignited electronically, allowing the military to build safer explosives, which won’t detonate when dropped.

“Let’s say you have a computer chip collecting information on the ground and 10 minutes later you want it to flip over, or self destruct, or ignite so that it will show up on an infrared or night-vision camera,” says Sailor. “What we’ve shown in this paper is that a small voltage can be used to ignite this chip, so you don’t need any sophisticated devices other than the tiny voltages you already have flowing through the electronic circuits of the chip. You just need to send them through the part of the chip that contains the blasting cap

Just think about all the computers in the WTC>

Lets see- Silica aka sand, pulverized cement and gypsum board, particles
of glass and fiberglass, silicates fron fireproofing materials and asbestos
from insulation (North Tower had asbestos up to 36 floor)

Because of large amount of cement dust was very alkaline - was said
that inhaling the dust was like snorting DRANO.

Many of my friiends spent several weeks at WTC doing rescue/recovery

So did 3 of my uncles. What a coincidence. They have some stories to tell.

What stinks is that the workers were told to hurry up and clean up, and that the air was fine to breath.
