During the initial days that followed the explosion and collapse of the World Trade Center (WTC) on September 11, 2001, fourteen bulk samples of settled dusts were collected at locations surrounding the epicenter of the disaster, and analyzed for persistent organic pollutants, including polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and select organo-chlorine pesticides. The PCBs comprised less than 0.001% by mass in three outdoor samples analyzed, indicating that PCBs were of limited significance in © 2006 American Chemical Society

104 the total settled dust across lower Manhattan. Likewise, organo-chlorine pesticides, were found at low concentrations in the bulk samples. Conversely, the PAHs comprised up to nearly 0.04% by mass of the settled outdoor dust in the six samples. Further size segregation indicated that the PAHs were found in higher concentrations on relatively large particles (10-53 |im). Significant concentrations were also found on fine particles (
