Sampling and analysis of polychlorinated biphenyls (PCB) in indoor air due to permanently elastic sealants

The Contamination of Indoor Environments with Persistent Organic Pollutants

“…This was attributed to: (a) the narrower temperature range indoors and (b) the mitigation of summer peaks in concentration due to Although this study appears the only data available for PBDEs, its findings regarding seasonal variation are consistent with earlier studies for PCBs. Specifically, concentrations of six PCB congeners in ten indoor environments in summer and winter were found to be significantly higher in summer, despite room temperatures being fairly constant throughout the year (Balfanz, Fuchs, and Kieper, 1993). Similarly, concentrations of dioxin like PCBs in five indoor environments in summer exceeded those in winter (Volland et al, 2005), while two other studies have reported positive correlations between PCB concentrations in indoor air and the temperature of the room (Benthe et al, 1992;Kohler et al, 2005).…”

The effect of ventilation on the indoor air concentration of PCB: An intervention study

“…Possible sources of indoor PCBs include caulks, transformers, fluorescent light ballasts, ceiling tiles [2,3]. The indoor air of buildings with PCB-containing materials might be contaminated to a considerable degree [2,4].…”

Metabolic activation of PCBs to carcinogens in vivo—A review

“…Other possible sources for indoor PCBs are believed to be data screen terminals (Digernes and Astrup, 1982), ceiling tiles (Anonymus, 1988) and fluorescent lights (Harris, 1985). It was reported that the concentration of PCBs in indoor air can be at least an order of magnitude higher than outdoor air (Balfanz et al, 1993;Vorhees et al, 1997;Wallace et al, 1996), although the sources are not completely clear. A recent publication from Great Britain found a daily average total PCB intake of 0.49 μg/person/day for adults of which 30.6% (4.2 -63%) was derived from inhalation exposure (Harrad et al, 2006).…”
