Could Dangerous PCBs be in Your Home?


Homeowners may want to test homes constructed or renovated between 1950 and 1978 for PCBs in caulk materials.

Westmont, NJ

Polychlorinated biphenyls (PCBs) are a type of organic compounds that has been classified as persistent organic pollutants due to its toxicity. Last month the U.S. Environmental Protection Agency (EPA) announced new guidance to communities on PCBs in caulk from buildings constructed or renovated between 1950 and 1978.

The EPA now recommends testing for PCBs in peeling, brittle, cracking or deteriorating caulk in buildings. Production of PCBs in the United States was halted in the late 1970s, but prior to then it was used in some electronics and building materials, including some caulks.

PCBs persist in old building materials and can contaminate surfaces, soils and the indoor air quality (IAQ). According to the EPA, PCBs have been shown to cause cancer and numerous other serious health effects in animals. These include issues with the immune system, reproductive system, nervous system, endocrine system and other negative health effects.

Millions of homes across the country were either constructed or renovated during the nearly 30 year time period of concern. Homeowners should be aware of the EPA’s guidance and consider testing suspect material for the dangerous PCBs.

EMSL Analytical, a leading provider of advanced environmental laboratory services, has recently doubled instrument capacity for PCB analysis at their NELAC certified laboratory in Westmont, New Jersey to handle the increased sample volume. “Concerned homeowners can easily submit a piece of caulking materials to EMSL to learn if they need to be concerned about PCBs in their home,” reported Joe Frasca, Executive Vice President at EMSL Analytical. “The cost is $250, but it is a small price to pay to ensure a property doesn’t have issues with PCBs.”
