Abstract After the collapse of the World Trade Center (WTC), bulk samples of settled dust were collected close to the WTC. Each sample was separated into four fractions according to aerodynamic particle size. All samples <2.5 μm fraction were analyzed by X-ray Fluorescence, and some 2.5 — 10 μm and 10 — 53 μm fractions were analyzed by Instrumental Neutron Activation Analysis. The 10 — 53 μm fraction contained the highest concentrations of elements used in construction materials (Al, Ca, Mg, Ti, Fe, Zn), while the <2.5 μm fraction also contained combustion related CI and Sb. Factor analysis of ambient samples (collected five blocks east of Ground Zero) was used to predict the factor scores for the 28 dust samples of the <2.5 μm fraction. A new combined dust factor was calculated and applied to predict the relative contribution of WTC dust to ambient PM2.5 concentrations in the three months after the WTC collapse.
