PCB-containing wood floor finish is a likely source of elevated PCBs in residents blood household air and dust: a case study of exposure

摘要

BackgroundPolychlorinated biphenyls (PCBs) are persistent pollutants identified worldwide as human blood and breast milk contaminants. Because they bioaccumulate, consumption of meat, fish, and dairy products predicts human blood concentrations. PCBs were also used widely in building materials, including caulks and paints, but few studies have evaluated the contribution of these exposures to body burden.
