Traduction en anglais : Management of indoor pollution with polychlorinated biphenyls (PCB) demonstrated in two schools at Hagen, Germany.
An indoor pollution of polychlorinated biphenyls (PCB) of about 4000 ng/m3 could be reduced by an average amount of 68% by temporary sealing of the primary source in combination with intensive cleaning.
The costs were around DM 100,000. - for the school building containing 12 classrooms.
Due to this procedure a continued usage of the building is possible until a concept of decontamination is available.
In another building the PCB indoor pollution was reduced by 73% in a representative trial restoration, whereas the stripping of the paint with a chemical caustic substance induced a significant reduction of the PCB concentration.
The usage of special air conditioners - called « Luftwäscher » - in the classrooms did not reduce the PCB concentration.
