چکیده
Pesticide residues in different crops, including food grains and vegetables are burning issues Bangladesh. Therefore, the present study was conducted to analyze organophosphorus pesticide three popular (cauliflower, hyacinth bean yard long bean) collected from five local markets of Narsingdi district The vegetable samples were extracted cleaned up using Quick, Easy, Cheap, Effective, Rugged Safe (QuEChERS) extraction technique analyzed by Gas Chromatography (GC) equipped with Flame Thermionic Detector (FTD). A total 45 analyzed. Among 15 bean, (20 % samples) contained above EU-MRL remaining did not contain any detectable selected pesticides. In case cauliflower, out samples, two (13% number EU-MRL. four (27% EU-MRLs. This reveals status residue contamination vegetables. Asian Australas. J. Biosci. Biotechnol. 2022, 7 (3), 114-121

Comparison of QuEChERS sample preparation methods for the analysis of pesticide residues in fruits and vegetables.
This article describes the comparison of different versions of an easy, rapid and low-cost sample preparation approach for the determination of pesticide residues in fruits and vegetables by concurrent use of gas and liquid chromatography (GC and LC) coupled to mass spectrometry (MS) for detection. The sample preparation approach is known as QuEChERS, which stands for "quick, easy, cheap, effec...
