Air quality testing within One North End Avenue has been and will continue to be the first priority of this Exchange. As we previously indicated, the Exchange has engaged Ambient Group, Inc., an extremely reputable independent laboratory specializing in this area, to monitor the Exchange’s air quality. The Exchange has also taken a pro-active approach on testing for dangerous chemicals outside the building. Air quality tests were performed on September 14th, 20th, 26th, October 4th, 9th, 12th, 18th, 23rd, 26th, 30th, November 6th, 8th, 13th, 15th, 20th and, to date, all results have been well below the EPA, OSHA, ASHREA, and ACGIH levels.
The air samples collected were tested for over 300 types and/or isomers of chemicals including transmission electron microscopy (TEM) for asbestos structures, polynuclear aromatic hydrocarbons, Acenaphtene, Acenaphthylene, Anthracence, Benz (a) anthracene, Benz (a) pyrene, Benzo (b) fluorathene, Benzo (ghi) perylene, Benzo (k) fluoranthene, Chrysene, Dibenz (a,h) anthracene, Fluoranthene, Flourene, Indeno (1,2,3 cd) pyrene, Napthalene, Phenanthrene, Pyrene, Cadmium, Chromium, Copper, Iron, Lead, Manganese, Nickel, Silica and Zinc.
In order to address additional environmental concerns raised by the prolonged combustion process that continues at the World Trade Center site, Ambient Group, Inc., has secured a high-volume air sampling monitor that tests for air borne chemicals outside the building including chlorinated dioxins, PCBs, brominated dioxims and polycyclic hydrocarbons (PAHs). The results from these reports indicated that the levels of these individual compounds are very low and do not indicate that the combustion processes occurring at the World Trade Center site are causing hazardous concentrations of dioxins and PCBs in the outdoor air at One North End Avenue.
All test results are posted and made available to all building occupants on a weekly basis.
