Asbestos continues to be public-enemy #1 when it comes to building material contaminants that property owners want to quickly identify and be thoroughly rid of when it comes to their properties and the air quality within it. That’s perfectly natural given the health risks associated with breathing in asbestos fibres, but there’s another potentially airborne contaminant that was incorporated into building materials in far previous decades that needs some attention paid to it as well.
PCBs, or Polychlorinated Biphenyls, were found in building materials used between roughly 1950 and 1979 in North America, both in Canada and the USA. As is the case with asbestos, one of the more common locations for them was in schools and other public-utility buildings and offices.
