Health Hazard Evaluation Report HETA 86-472-1832, Commercial Office Buildings, Boston, Massachusetts
Surface and air contamination by polychlorinated biphenyls (PCBs) (1336363), polychlorinated dibenzofurans (PCDFs), and polychlorinated dibenzo-p-dioxins (PCDDs) were studied in two office buildings (SIC-9199) in Boston to obtain background levels for comparison with cleanup guidelines for another building, the 50 Staniford Street Office Building, which had experienced a transformer fire in 1981. Charles River Park Properties requested the study. Concentrations of PCBs on workspace surfaces ranged from less than 1 to 69 micrograms/square meter (microg/m2) and less than 1 to 100mecrog/m2. Concentrations of PCDFs on work surfaces ranged from 0.48 to 5.4 nanograms per square meter (ng/m2), and PCDD concentrations from 2.8 to 146ng/m2. Concentrations of PCBs in workspace air samples ranged from 0.06 to 0.31 micrograms per cubic meter. Airborne PCDFs were undetected except for hepta and octa isomers. PCBs were significantly correlated with PCDDs and PCDFs in terms of surface concentrations.
