Continuing sources of PCBs: The significance of building sealants

Robson, Matthew / Melymuk, Lisa / Csiszar, Susan A. / Giang, Amanda / Diamond, Miriam L. / Helm, Paul A.

AbstractTo investigate the significance of building sealants as a remaining source of PCBs to the environment a combined measurement campaign and GIS-based stock estimation were undertaken for Toronto, Canada. This showed that 14% of buildings measured had detectable quantities of PCBs present in sealants, with concentrations from 0.57mg/g to 82mg/g (n=95). We then constructed a GIS-based database of remaining PCB-containing sealants in Toronto. This showed that there is an estimated 13t still present in the city. Mass balance calculations showed that up to 9% had been lost via volatilization alone. This potentially has important implications for both human exposure and the continued presence of PCBs in the environment.
