A method was established for the determination of five acylpyrazole pesticide residues in edible vegetable oils using gas chromatography-negative chemical ionization-mass spectrometry (GC-NCI-MS).  After being identified by GC-NCI-MS, the extracts were quantified using an external standard method that employs a matrix correction standard curve.
