“…A further advance in this field is represented by the use of the isotope dilution method in conjunction with MS/MS, thus permitting contaminant residues to be assayed at the sub‐picomole level 18–20. Sample preparation, as one might expect, is an important step and most of the reported extraction methods are based on solvent extraction,21, 22 solid‐phase extraction (SPE),23 XAD resins,24 ultrasonic‐assisted matrix solid‐phase dispersion (UA‐MSPD)25 and, recently, use of the QuEChERS method 26 …”

Crop control is an important issue in both developed and developing countries. An environmentally friendly approach is represented by the so-called Integrated Pest Management (IPM), whereby synthetic pesticides are only applied as a last resort, under the strict control of suitable experts. European and US regulatory authorities, such as the US EPA, are constantly assessing the risks of exposure to the organophosphate (OP) class of pesticides and, among these, specifically dimethoate. The use of dimethoate is still allowed in many crops, including olives, which once was based in the Mediterranean area but now is expanding rapidly throughout the world. An important aspect of IPM protocols is represented by the availability of reliable and sensitive methods to detect pesticides residues. This paper describes an isotope dilution dimethoate assay based on the application of electrospray ionization tandem mass spectrometry (ESI-MS/MS) by means of a deuterium-labeled internal standard.

“…OPPs in edible oils and fats were determined by injector-internal headspace analysis, in which the oil or fat diluted with acetone was introduced directly by splitless injection into a moderately heated injector (17). OPPs were routinely screened in biota samples by GPC and CGC with thermionic detection (18). OPPs and primary and secondary metabolites were determined in beef tissue using silica gel HPLC with an acetonitrile/water gradient and diode array detection (19) and phenolic ester cleavage products of some OPPs in water by HPLC with electrochemical detection (110).…”
