The polychlorinatedbiphenyls (PCBs) collected from the trading floors and collected from the 9s'
and 10° floor of 22 Thames Street are all below detectable limits. The polychlorinatedbiphenyls (PCBs)
levels in the buildings are acceptable.
The polynuclear aromatic hydrocarbons (PAHs) are produced through combustion of fuels,
found in fuels, plastics, and other building components. The PARs in air samples were collected from
areas considered representative of the building. Two samples wore collected from the trading floors and
one sample was collected from the 9"` and 10' floor of 22 Thames Street to characterize the building and
to accelerate the building screening process. The PAHs in air realts are presented in the tables below.
