✦ Synopsis

The influence of the analytical error in the multidimensional gas chromatographic determination of mono-ortho substituted chlorobiphenyls in biota on the calculation of their TCDD equivalents is negligible compared with the influence of the high uncertainty of toxic equivalency factors reported in the literature.

The mono-o&o chlorobiphenyls (CBS) 60,74,114,123,157,167 and 189 were determined in Aroclor mixtures and aquatic organisms by multidimensional gas chromatography with electron capture detection (MDGC/ECD), using a combination of an Ultra 2 and an FFAP column. MDGC/ECD is recommended as the most suit
