During three periods from May 1978 until January 1979, 165 milk samples were taken, They were sampled in four areas in the Netherlands and analysed for individual chlorinated biphenyls by glass-capillary gas chromatography. In almost all of the samples seventeen compounds could be identified. On average nine of these compounds were present above the 2mu-g/kg level on a fat basis. It is shown that the PCB pattern in milk is not comparable with the peak pattern in technical mixtures, indicating that quantification based on comparison with Aroclor 1260 or 1254 is not desirable.
