PCB in Buildings: Identification and Remediation
Polychlorinated biphenyls (PCB) are among the most dangerous pollutants found in buildings. Widely used in Germany from the 1950s to the 1980s as plasticizers, flame retardants, and insulating fluids, PCB has been banned since 1989. However, many existing buildings still contain PCB-laden materials that must be professionally removed during renovation or demolition.
Where Is PCB Found?
PCB is most commonly found in elastic joint sealants used between precast concrete elements in 1960s and 1970s buildings. Other sources include paints and coatings, ceiling tiles, electrical capacitors and transformers, adhesives, and fire-protection coatings.
Health Risks
PCB is classified as carcinogenic under German hazardous substances regulations (GefStoffV). Exposure can cause cancer, immune system disorders, reproductive problems, skin diseases (chloracne), and neurological damage. PCB off-gassing from sealants into indoor air is particularly dangerous, with the precautionary limit set at 300 ng/m3.
PCB Action Levels
German regulations define clear thresholds: below 300 ng/m3 requires monitoring only, 300-3,000 ng/m3 requires medium-term remediation, and above 3,000 ng/m3 demands immediate action and usage restrictions.
Remediation Process (TRGS 521)
Professional PCB remediation follows TRGS 521 regulations and includes remediation planning, authority notification, containment with negative pressure, mechanical removal under full protective equipment, surface decontamination, post-remediation air monitoring, and expert clearance certification.
