Polychlorierte Biphenyle (PCB) in Fugendichtungsmassen von Gebäuden : Bestandsaufnahme für Berlin und neue Innenraumquellen.
Traduction en anglais : Polychlorinated Biphenyls (PCB) in permanently elastic sealants In buildings : Stocktaking for Berlin, and for new indoor sources.
Polychlorinated Biphenyls (PCB) in Permanently Elastic Sealants In Buildings Stocktaking for Berlin, and for New Indoor Sources : Since 1990 in Berlin the building blueprints and potaining documents for public utility buildings, in particular schools and child-care centres, have been serutinised and/or buildings have been visited for the possibility of the presence of elastic sealants containing PCB.
Pursuant to this, samples of the sealing material of suspected buildings were examined and air in the rooms was measured.
Results of measurements (n=410) in community rooms of schools and child-care centres were an average value of 114ng/m3 (maximum 7.360 ng/m3) and a geometrical mean of 155 ng/m3.
For measurements in schools (n=308), the geometrical mean was 229 ng/m3, whereas in child-care centres (n=102) it was 48 ng/m3.
Within the framework of the procedural method described above regarding the investigation of suspected buildings, about 15% of the school buildings and 3% of the child-care centres had indoor air values of over 300 ng/m3 (value indicating need for taking precautions) and 5% of the school buildings had more than 3.000 ng/m3 (the value warrauting an intervention, according to the now defunct Federal Health Office).
No values over 3.000 ng/m3 have been measured up to now in the community rooms of child-care centres. (...)
