Indoor Air Polychlorinated Biphenyl Concentrations in Three Communities Along the Upper Hudson River, New York

Polychlorinated biphenyl (PCB) concentrations in indoor air were measured in upstate New York as part of a non-occupational exposure investigation. Adjacent studied communities have numerous sites of current and former PCB contamination, including 2 capacitor-manufacturing facilities. Study area home PCB indoor air concentrations were not significantly different than in comparison area homes. Study area home total PCB concentrations were 0.3-114.3 ng/m3 (median 7.9). For comparison area homes, concentrations were 0.3-233.3 ng/m3 (median 6.8). No correlations were observed between PCB concentrations in indoor and outdoor air; indoor concentrations were generally 20 times higher than outdoor concentrations Of catalogued home characteristics, the presence of fluorescent lights was significantly associated with total PCB concentration only in the study area. Indoor PCB concentrations measured in this work were similar to those in other communities with known PCB-contaminated sites and similar to concentrations reported in other northeastern US locations.
