Chemical emissions from flooring can predict polychlorinated biphenyl (PCB) concentrations in room air, according to NIEHS-supported research. The findings could inform targeted remediation strategies for indoor spaces.

For decades, manufacturers blended PCBs with other substances as plasticizers for use in caulks, adhesives, and other materials. Although the U.S. banned PCB production in 1976, tainted building materials can still off-gas, meaning they can release gaseous chemicals into indoor air people breathe. Inhaling PCBs may lead to cancer, hormone dysfunction, or learning disabilities.
