Sept. 5, 2002: New IAQ Technique Used At Ground Zero
Recently, AQS used the DustVOC to evaluate the acceptability of several office buildings in New York City following the 9/11 attacks. Buildings within close proximity to the Twin Towers had windows blown out and interior surfaces were contaminated with dust and debris resulting from the collapse of the towers. According to AQS, although the buildings had been cleaned, building dust analysis showed elevated levels of chemicals that were two to three times higher than typical commercial building dust. AQS also says that many of the chemicals found were known irritants and carcinogens. AQS recommended that all contaminated materials be removed if more thorough cleaning does not take care of the problem.
