ABSTRACT
The levels of PCB 28, 52, 101, 153, 138 and 180 were determined in blood samples of subjects (mainly teachers; n = 18) who had worked in a PCB-contaminated school-building for many years (average 14.2 years). The PCB concentrations in indoor air ranged up to 13,500 ng/m3. For comparison PCB blood levels were determined in 18 teachers working in schools not contaminated by PCB. The subjects of the reference group were matched with the exposed subjects with respect to age and gender. PCB 28, 52 and 101 were not detectable in the blood samples (detection limit 0.1 microgram/l). In the exposed subjects blood levels of PCB 153 and 138 were, on average, slightly higher and the levels of PCB 180 slightly lower when compared with the reference subjects, but the differences were not statistically significant. The levels of PCB 153, 138 and 180 increased with age. With the exception of two subjects the levels of these congeners were below the reference values proposed by Kappos et al. The results show that inhalative exposure to PCB 153, 138 and 180 is very low in comparison to PCB background exposure via food. Due to rapid metabolisation and elimination the blood levels of PCB 28, 52 and 101 are usually very low.
