    Description / Table of Contents: Summary All individual polychlorinated biphenyls (PCB's) present in human milk and in butter were quantified. For calibration, a technical PCB mixture of known composition was used. The “real” total PCB concentration was determined by the addition of concentrations of the individual components. In human milk the calculated content was 50% and in butter 40% lower than values obtained by the usual calculation based on evaluation of some higher peaks of technical PCB mixtures. In addition, the approximate metabolization rates of the individual PCB components were calculated by comparison with the pattern of a technical PCB mixture (Clophen A 60).
    Notes: Zusammenfassung Sämtliche in Frauenmilch und in Butter vorkommenden Komponenten des Gemisches der polychlorierten Biphenyle (PCB) wurden quantitativ bestimmt. Die Eichung erfolgte dabei mit Hilfe eines technischen PCB-Gemisches von bekannter Zusammensetzung. Der „wahre“ Gesamtgehalt an PCB, berechnet durch Addition der Einzelwerte war bei Frauenmilch um 50%, bei Butter 40% niedriger als die Konzentrationen, die sich nach der sonst üblichen Berechnungsweise durch Bezug auf einige hohe Peaks technischer PCB-Gemische ergeben. Außerdem wurden die annähernden Abbauraten der einzelnen PCB-Komponenten im Vergleich zu einem technischen PCB-Gemisch (Clophen A 60) berechnet.
