Title

SIMULTANEOUS DETERMINATION OF RESIDUE FROM 58 PESTICIDES IN THE WHEATFLOUR CONSUMED IN TEHRAN, IRAN BY GC/MS

Pages

  1048-1058

Abstract

 FOOD SAFETY has a direct impact on human health and as such is a growing concernworldwide. Presence of harmful pesticide residue in food is a serious cause for concern amongconsumers so it is important to monitor levels of PESTICIDES in foods. The aim of this studywas simultaneous determination of concentrations of 58 PESTICIDES in 40 WHEAT FLOUR samplescollected from Tehran market in January, 2014. The city under study (Tehran) was divided intofive districts and samples were collected independently from each district and sourced fromdifferent bakeries (n=40). A gas chromatography-mass spectrometry single quadrupole selectedion monitoring «GC/MS-SQ-SIM» method was used to quantify residue of 58 PESTICIDES inthe WHEAT FLOUR samples. Four of the 40 samples showed contamination with Malathion (2samples: 50. 96 ± 11. 38 and 62. 088 ± 11. 38 ppb) and 2, 4-DDE (2 samples: 19. 88± 15. 24 and13. 7 ± 15. 24 ppb). that had levels below MRLs of these PESTICIDES in Iran. Averages of recoveryof PESTICIDES at 6 concentration levels were in the range of 81. 61-118. 41%. The method wasproven as repeatable with RSDr in the range of 6. 5-29. 45% for all concentration levels. Thelimit of quantification for 37 of the tested PESTICIDES was calculated as 15 ppb and for the other21 tested PESTICIDES, the concentration was 25 ppb. In summary, results of these tests suggestedthat the WHEAT FLOUR consumed in Tehran, was within safety limits in terms of levels of pesticideresidues.
