The extraction and clean-up procedures were optimised, and using stable isotope-labelled internal standards for each analyte, relative standard deviations (RSDs) of 0.92-10.6% and spiked sample recoveries of 80.6-97.8% were obtained. Limits of detection for PAHs were in the range of 0.15-0.77 mu g/kg and those for phthalates were in the range of 4.6-10.0 mu g/kg. The calibration curves exhibited good linearities with regression coefficients of R-2 >= 0.99. Twelve edible oils were examined to evaluate the efficiency of this method. Among the 12 analytes, dibutyl phthalates (DBP), diethylhexyl phthalates (DEHP), diethylhexyl adipate (DEHA), benzo[a] anthracene (B[a] A), chrysene (Chry) and benzo [b] fluoranthene (B[b] F) were detected in the range of 1.17-806 mu g/kg.
