Traduction en anglais : Human Biomonitoring on polychlorinated biphenyls in a contaminated primary school.
In the classroom air on a primary school polychlorinated biphenyls were present in a wide range extending to 10.220 ng/cbm ; in a side room even 19.550 ng/cbm were measured.
The school was closed down, a flame retardant paint was detected to be the main source of this contamination. 130 differently exposed persons gave blood specimens for measurement of PCB concentrations.
Compared with a comparative reference collective of equal age reported by the analysing laboratory, the PCB blood concentrations of 92 actual pupils were even lower.
A comparison with five near-representative child collectives of South Germany did not show any obvious difference.
The reference values of the German Human Biomonitoring Commission were exceeded by 4 of 92 pupils for PCB 138, by 6 pupils for PCB 153 and by 6 pupils for PCB 180.
In a group of 9 teachers and 1 cleaning person the median values of reference collectives of equal age reported by the analysing laboratory were exceeded by 8 persons for PCB 138,7 persons for PCB 153 and 8 persons for PCB 180.
Percentiles of these reference collectives and the reference values of the German Human Biomonitoring Commission were not exceeded. (...)
