“…The determination of some isomeric pesticides is problematic: sometimes only one isomer is reported, because either the isomers co‐elute or one isomer is completely ignored. This seems to be the case for mevinphos by LC–MS/MS,1, 2 dimethomorph by LC–MS/MS,2–6 phosphamidon by GC–MS/MS7 and LC–MS/MS2, 5, 8 and chlorfenvinphos by LC–MS/MS 5. However, other methods monitored both isomers, e.g.…”

The mass spectrometric behavior of four pairs of stereoisomers was investigated by liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS). The E- and Z-isomers of the pesticides chlorfenvinphos, dimethomorph, mevinphos and phosphamidon-each with one double bond-were chosen for this study. The MS response of the individual isomers was investigated by infusing the isomers individually into the MS or after the separation of isomer mixtures via high-performance liquid chromatography (HPLC). In the case of dimethomorph, the same MS response was found for the two isomers. In contrast to that, the individual isomers of chlorfenvinphos, mevinphos and phosphamidon showed different MS response both in the single ion monitoring (SIM) mode in single quadrupole MS and multiple reaction monitoring (MRM) mode in tandem MS. The MS response of the isomers partly depends on (1) the declustering potential of the precursor ion in the SIM mode, (2) the selected transition and (3) the collision energy in the MRM mode. Consequently, quantification by summation of the peak areas of the isomers is inaccurate due to over- or underestimating of one of the stereoisomers. Accurate quantitative results can only be achieved when the compound-specific MS parameters are separately determined for each isomer. This can be done by using pure isomers or by the determination of the MS parameters after HPLC separation and the measurement of the actual isomer ratio with an independent technique.

“…Although gas chromatography is the technique preferably used for analysing pesticide residues in agricultural food products (Huskova et al 2008;De Pinho et al 2010;Taga and Bilgin 2010), the use of liquid chromatography for such applications is increasing. Nowadays, liquid chromatography coupled with mass spectrometry (LC-MS) is becoming one of the most powerful techniques for residue analysis of polar, ionic or low volatile pesticides in fruits and vegetables (Hatakeyama et al 2006;Pang et al 2006;Ferrer et al 2007;Wang et al 2007;Pan et al 2008;Takatori et al 2008;Tseng et al 2009). …”

In this study, 175 pesticide residues in various vegetable and fruit samples grown in different regions of Hatay, Turkey, were investigated. Residue analyses were performed using liquid chromatography-tandem mass spectrometry with the QuEChERS method. In tomato, plum and apricot samples, pesticide residues were below the limits of detection. In other samples, at least one pesticide residue was detected. Twelve pesticides (acetamiprid, carbendazim, chlorpyrifos, fenarimol, fludioxonil, hexythiazox, imidacloprid, metalaxyl, pyridaben, pyriproxyfen, thiabendozole, triadimenol) were found at levels between 0.003 and 0.759 mg kg(-1). Only in cucumber samples, acetamiprid residues were found at levels greater than the maximum acceptable limit in Turkish Food Codex and European Union maximum residue limits (EU MRLs). In other samples, the detected residue amounts are less than the MRLs declared in the Turkish Food Codex and EU MRLs.

“…In order to overcome the question of undesirable recoveries for certain PH-sensitive pesticides, the acetatebuffering version QuEChERS method was put forward by Lehotay et al in 2005 and then received as ''AOAC Official published Method 2007.01'' (Lehotay, Ma s stovská, and Lightfield 2005;Lehotay 2007), and the citrate-buffering version in combination with accessorial graphite carbon black (GCB) cleanup was entitled the European Committee for Standardization (CEN) Standard Method EN 15662 (2008) European Standard EN 15662, 2008). Additionally, necessary moisture was obtained through adding water to dry samples (Payá et al 2007;Takatori et al 2008;Nguyen et al 2008;Koesukwiwat, Sanguankaew, and Leepipatpiboon 2008;Koesukwiwat et al 2010;Mastovska et al 2010), and an amount of fat components removed by freeze-out, adding hexane and=or C18 sorbent were introduced to the QuEChERS methodology Payá et al 2007;Takatori et al 2008;Nguyen et al 2008;Tsiplakou et al 2010;Przybylski and Segard 2009).…”

Determination of Pirimicarb and Paclobutrazol Pesticide Residues in Food by HPLC-ESI-MS with a Novel Sample Preparation Method

et al. 2013

View full text Add to dashboard Cite

A rapid and simple extraction method for the determination of the pesticides of pirimicarb and paclobutrazol was developed by liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Extraction was performed by using a modified QuEChERS-based (a portmanteau word for Quick, Easy, Cheap, Effective, Rugged, and Safe) sample preparation procedure. The ''QuEChERS'' method combines salting-out liquid-liquid extraction with acetonitrile and a dispersive solid-phase extraction (d-SPE) clean up. Validation studies were carried out in tomato, cucumber, cauliflower, apple, grape, pear, mung bean, peanut, and shrimp as representative matrices. No significant matrix effect was observed for tested pesticides. Limits of quantification were lower than 10 lg kg À1 and recoveries of the spiked samples were in the range between 74% and 110% (with intra-day precision, expressed as relative standard deviations, lower than 9.5%) for all the pesticides. The result of this strategy was satisfactory and the developed method was successfully applied to detect the pesticides of pirimicarb and paclobutrazol in various food matrices.
