Note: Exact publication date unknown. Introduction: The United States Environmental Protection Agency (EPA) has begun a reassessment of the presence of World Trade Center (WTC) dust in residences, public buildings, and office spaces in New York City, New York. Meeker and others (2005a) have identified slag wool (a man-made vitreous fiber, MMVF), gypsum (CaSO4_2H2O) (or anhydrite (CaSO4)), and phases compatible with concrete as signature components of the WTC dust. In addition to these phases, other MMVF, metal or metal oxides, mineral material, and asbestos are present in trace to minor amounts. Background dust samples collected from residences, public buildings, and office spaces will be analyzed by multiple laboratories for the presence of WTC dust. Other laboratories are currently studying WTC dust for other purposes, such as health effects studies. To assist in inter-laboratory consistency for identification of WTC dust components, this particle atlas of phases in WTC dust has been compiled.
