Environmental Studies of the World Trade Center Area After the September 11, 2001 Attack.
This report describes the results of an interdisciplinary environmental characterization of the World Trade Center (WTC) area after September 11, 2001. The scientific investigation included two main aspects: imaging spectroscopy mapping of materials around the WTC, and laboratory analysis of samples collected in the WTC area. The report includes maps, graphs, and remotely sensed images of the area around Ground Zero, including mineral distribution maps, a sediment map, and a map of the dust plume. Analyses of ground sampling show that the dusts released from the WTC building collapse are largely composed of particles of glass fibers, gypsum, concrete, paper, and other miscellaneous materials commonly used in building construction, with minor asbestiform minerals.
