Determination of pesticide residues in eggplant using modified QuEChERS Extraction and Gas chromatography

Abstract
Food poisoning through pesticide contamination is a burning issue now a days all over the world. Peoples are suffering and dying in a large number from this problem every year. It is also a threat to the future generations. Foods like vegetables are being contaminated with pesticide for larger yield but the residual effect of this pesticide is devastating. So the study about the determination of pesticide residue in vegetables of a certain place is an important matter of public interest. This study reflects the overall scenario of pesticide residue contamination in eggplant available in the local markets of Mymensingh Sadar, Mymensinghfrom December 2015 to June 2016. 50 samples of eggplant were analyzed which were collected from 10 markets of Mymensingh Sadar, Mymensingh. A simple and efficient multiple pesticide residue analytical method (QuEChERS extraction) and gas chromatography-flame thermonized detector (GC-FTD) were used for the determination of pesticide residues. Among the 50 analyzed samples, 11 (22% of the total number of the samples) contained pesticide residues of diazinon, dimethoate, quinalfos, and chlorpyrifos, of which, 2 had multiple pesticide residues and 5 samples contained residue above the European Union maximum residue limit (EU-MRLs). Chlorpyrifos was detected as the most used pesticide in eggplant in the studied area. Eggplant samples collected from K.R market did not contain any residues of pesticides.
