“…The identification and quantification of pesticide in the food are becoming the public interest. Several researchers [12][13][14][15][16][17][18] analyzed pesticide residues in fruit and vegetables in Greece, India, Spain, China, Japan and other developed country. A very little reference is available on the presence of pesticide residues in vegetables in Bangladesh [19].…”

Three modifications of the QuEChERS (quick, easy, cheap, effective, rugged and safe) method for determination of 35 endocrine disrupting pesticides in samples with high acid content such as lemons were studied. Pesticides extraction was performed using the original QuEChERS method, citrate buffered QuEChERS method (EU version) and acetate buffered QuEChERS method (AOAC version). Final extracts were evaluated by fast gas chromatography-mass spectrometry (GC-MS) analysis. Validation experiments for all three methods were performed using a spiked pesticide free lemon matrix and matrix-matched standard solutions. Four concentration levels (1, 20, 50 and 250 mg kg À1 ) were tested. Recoveries from 70 to 120% with a relative standard deviation <20% were obtained for the majority of pesticides. Linearity was evaluated at a concentration range of 1-250 mg kg À1 for the buffered QuEChERS (AOAC) method with coefficients of determination (R 2 ) higher than 0.9552 and for the original QuEChERS method with R 2 higher than 0.9232. The best linearity was obtained for the citrate buffered method with R 2 higher than 0.9656. The limit of detection (LOD) of the buffered QuEChERS (AOAC) method ranged between 0.1 and 18.4 mg kg À1 , for the citrate buffered QuEChERS method between 0.1 and 23.6 mg kg À1 and for the original QuEChERS method between 0.1 and 14.2 mg kg À1 . Results obtained by the three different QuEChERS methods were compared. The citrate buffered method is more suitable for the tested pesticides than the other two QuEChERS methods.Although the QuEChERS method is widely applied, it was shown that in difficult matrices such as lemons, the choice of modifications is analyte/matrix dependent. The three developed and validated methods were applied to the analysis of real citrus samples.

“…An approach utilizing narrow-bore columns for pesticide residues analysis was developed in our research group. Fast separation with narrow-bore capillary columns as a way to reduce the run times provides separation efficiency comparable or even higher than conventional capillary columns [ 4 , 44 , 85 ]. The wide majority of high-speed GC applications described in the literature have been carried out by means of reduced I.D.…”

Endocrine disrupting chemicals, among them many pesticides, alter the normal functioning of the endocrine system of both wildlife and humans at very low concentration levels. Therefore, the importance of method development for their analysis in food and the environment is increasing. This also covers contributions in the field of ultra-trace analysis of multicomponent mixtures of organic pollutants in complex matrices. With this fact conventional capillary gas chromatography (CGC) and fast CGC with mass spectrometric detection (MS) has acquired a real importance in the analysis of endocrine disrupting pesticide (EDP) residues. This paper provides an overview of GC methods, including sample preparation steps, for analysis of EDPs in a variety of matrices at ultra-trace concentration levels. Emphasis is put on separation method, mode of MS detection and ionization and obtained limits of detection and quantification. Analysis time is one of the most important aspects that should be considered in the choice of analytical methods for routine analysis. Therefore, the benefits of developed fast GC methods are important.
