PCBs in a Child Care Center

Friday, July 20th, 2012

Cambridge Environmental recently evaluated whether polychlorinated biphenyls (PCBs) detected in the air in a Child Care Center would be harmful to infants and others.  The measured concentrations exceeded U.S. EPA’s guidelines for allowable concentrations of PCBs in air in schools, but were, in our toxicologic judgment, acceptably small.  Nonetheless, we recommended that the building be systematically surveyed, in hopes of finding important PCB-sources, and then of determining what remediation, if any, would be beneficial.
