Definitive confirmation of pesticide residues was obtained by comparison of parent and fragment ion intensities and mass numbers of eluted pesticides and reference pesticides. Table I lists the residues encountered and the mass numbers and intensities of the characteristic fragments employed for identification in the adipose tissue sample. The mass spectral fragmentation patterns for all the compounds included in Table I with the exception of -HCH have been adequately discussed by other investigators (7). 

Within the framework of this philosophy, this symposium is concerned with several topic areas pertinent to the problems associated with the identification and confirmation of pesticide residues at submicrogram levels. The purpose of this symposium is to survey the present status of the classical physical, chemical, and biochemical techniques employed for residue analysis to evaluate critically the more recently applied, relatively unexploited techniques which have become available for the detection, quantitation, and characterization of pesticide residues and finally, to examine and discuss the current needs and problems, stimulate and encourage greater research activity, and point the way to future developments in the analysis of pesticide residues.

A large number of analytical methodologies aiming the detection of pesticide residues in VOO at very low concentration levels are being published nowadays. Among them, GC remains the most extensively used technique in routine laboratories for the analysis of these analytes in VOO it is usually employed in combination with ECD, NPD, and EPD. However, the relatively low sensitivity needed for some pesticides and the difficulties in confirmation of results due to the complexity of the matrix under study force to use GC-MS. With the use of GC-MS/MS techniques, simultaneous determination and confirmation of pesticide residues has been obtained in one analytical run this improves the analytical accuracy and shortens the analytical time [112,113],...
