dioxin-like PCBs in ambient air, but no such analytical data have been
published.
Although indoor air levels of PCBs are generally very low, in certain instances
levels of up to several µg/m 3 have been detected. For people living or
working in such buildings, exposure to PCBs via air could contribute
significantly to the overall PCB exposure.
Because of the potential importance of the indirect contribution of PCBs
in air to total human exposure, it is important to control known sources as
well as to identify new sources.
