Abstract By September 14, three days after the initial World Trade Center collapse, efforts at fire suppression and heavy rainfall had extinguished the immediate surface fires. From then until roughly mid-December, the collapse piles continuously emitted an acrid smoke and fume in the smoldering phase of the event. A knowledge of the sources, nature, and concentration of these aerosols is important for evaluation and alleviation of the health effects on workers and nearby residents. Here we build on our earlier work to ascribe these aerosols to similar processes that occur in urban incinerators. The simultaneous presence of finely powdered (circa 5 μm) and highly basic (pH 11 to 12) cement dust and high levels of very fine (< 0.25 μm) sulfuric acid fumes helps explain the observed health impacts, as do the high levels of very fine mass and its constituents. The unprecedented levels of several metals in the very fine mode aerosols can be tied to the liberation of those metals that are both present in elevated concentrations in the debris and have depressed volatility temperatures caused by the presence of organic materials and chlorine under anaerobic conditions. Health concerns focus on the workers at the site, as plume lofting protected most of New York City.
