"The small particles are really much more injurious to the body, to the lungs, than inhaling the larger particles. The gypsum tended to be in larger particles, and that's why they were coughed out as the "WTC cough". When you breath something in that is extremely fine, like less than 2.5 microns, they will go right past the coughing mechanism, those hairs that when something hits the hair it triggers them all and you cough and you cough it out and so forth. Something that's really tiny can get past all of those and then all the way down to the bottom of your lungs and stay there for good long periods of time." Dr. Marjorie Clarke
