determination of 14 organochlorine pesticides (OCPs) residues in tamarind peel, fruit and commercial pulp was optimized using gas chromatography (GC) coupled with electron-capture detector (ECD) and con firmation by GC tandem mass spectrometry (GCeMS/MS). Five procedures were tested based on the original QuEChERS method. The best one was achieved with increased time in ultrasonic bath. For the extract clean-up, primary secondary amine (PSA), octadecyl-bonded silica (C18) and magnesium sulphate ( MgSO 4) were used as sorbents for tamarind fruit and commercial pulp and for peel was also added graphitized carbon black (GCB). The samples mass was optimized according to the best recoveries (1.0 g for peel and fruit; 0.5 g for pulp). The method results showed the matrix-matched calibration curve linearity was r2> 0.99 for all target analytes in all samples. The overall average recoveries (spiked at 20, 40 and 60 mg kg1) have been considered satisfactory presenting values between 70 and 115% with RSD of 2e15 % (n ¼ 3) for all analytes, with the exception of HCB (in peel sample). The ranges of limits of detection (LOD) and quantification (LOQ) for OCPs were for peel (LOD: 8.0e21 mg kg1; LOQ: 27e98 mg kg1); for fruit (LOD: 4e10 mg kg1; LOQ: 15e49 mg kg1) and for commercial pulp (LOD: 2 e5 mg kg1; LOQ: 7e27 mg kg1). The method was successfully applied in tamarind samples being considered a rapid, sensitive and reliable procedure.
