Ongoing research, legislation and regulation continue to raise the visibility of the potential risks and hazards of PCBs in building materials.
As Chairman of the American Industrial Hygiene Association’s (AIHA) Committee on Indoor Environmental Quality, I was proud to be involved in the development of a newly released white paper on this topic.
“PCBs in the Built Environment” provides a comprehensive overview of the issue, evaluates the exposure potential for building occupants, and identifies gaps in the current knowledge base that would help occupational and environmental health professionals better understand the associated public health risks.
PCBs are a group of manmade chemicals that were used to make various building materials and products, such as caulking, grout and light ballasts, from the 1950s to 1970s. In the U.S., the production of PCBs was banned in 1979, and their use and disposal is restricted, due to the associated health and environmental risks. Building owners and occupants are rarely aware of the existence of these materials, or the potential dangers.
The new AIHA white paper contributes to the discourse on the issue by reviewing the following areas:
While I served as the paper’s editor, my TRC colleague Bart Ashley, CIH, CSP chaired the paper’s full development. It was a yearlong process involving extensive research, the participation and collaboration of many industry experts representing a number of AIHA Committees—Construction, Environmental Issues, Exposure Assessment Strategies, Indoor Environmental Quality and Risk Assessment – and an outside peer review process. Bart and I extend our sincere thanks to everyone involved.
Together, the paper’s authors concluded that action in the following areas will help develop sound public policy related to PCBs:
