[Article in German]


PAH analyses in vegetables are often difficult to carry out; therefore two different clean-up methods, which allow elimination of interfering matrix components such as essential oils, waxes, carotinoids and chlorophylls were developed. Clean-up of 32 different vegetables samples consisted of either Bio-Beads S-X3 chromatography or semi-preparative HPLC on silica gel Si-60. PAH were determined by capillary GC-MS, which allowed the application of deuterium-labeled internal standards. The results are presented; higher PAH contamination was detected in kale and parsley.
