Abstract:
A wide variety of chlorinated aromatic compounds are released intentionally and/or unintentionally in the environment. Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) and polychlorobiphenyls (PCBs) are well known environmental contaminants. Another class of organochlorinated compounds consists of polychlorinated biphenylenes (PCBPs), whom toxicity is comparable to PCDDs and shows the same mechanism of action. It is known that the formation of PCBPs is strictly correlated with the release and combustion or pyrolization of capacitor and transformer fluids, office furnishings and computers. Despite these assumptions, there are very limited and dated studies on these toxic chemicals except observations on building fires. 2,3,6,7-TeCBP concentrations (the most common congener) have been investigated in air sampled in an industrial building containing electric material after a fire, in an extended time, in order to evaluate the persistence. The concentration was monitored over an extensive range of time and compared to ambient air levels.
