Monitoring of Pesticide Residues in Major Vegetables Collected from Different Markets of Gazipur and Narsingdi

Abstract

The study was conducted to analyze pesticide residues in three common vegetables (country bean, cauliflower and yard long bean) from 5 different markets of Gazipur and Narsingdi. The collected samples were analyzed using Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction technique and Gas Chromatography (GC) coupled with Flame Thermionized Detector (FTD) for the detection and determination of pesticide residue in country bean, cualiflower and yard long bean of 30 samples in each case. Out of 15 samples of country bean, 2 samples contained pesticide residues with above MRL in Gazipur, whereas it was 3 samples above MRL in Narsingdi and no detectable residues of the sought pesticides were identified from remaining samples. In case of cauliflower, among the same number of analyzed samples, 2 samples from each location contained pesticide residues with above MRL and rest of the samples had no detectable pesticide residues. From 15 yard long bean samples from each surveyed area, pesticide residues with above MRL was identified and quantified in 3 samples from each region. No pesticide residue was found from remnant samples. This study reflects the overall scenario of pesticide contamination in vegetables specially in country bean, cauliflower and yard long bean available in the local markets of Gazipur and Narsingdi city, which will help the consumer to be aware of their health and safety
