DETERMINATION OF PESTICIDE RESIDUES IN COUNTRY BEAN AND EGGPLANT COLLECTED FROM BARISHAL DISTRICT OF BANGLADESH

Abstract

The study was carried out to analyze pesticide residues in two common vegetables (country bean and eggplant) collected from five different locations of Barishal district during November 2019 to February 2020. The collected samples were analyzed using Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction technique and Gas Chromatography (GC) coupled with Electron Capture Detector (ECD) for the determination of residues of acetamiprid, cypermethrin, lambdacyhalothrin, and thiram in 30 samples of country bean and 30 samples of eggplant.

Among

the 30 analyzed samples of country bean, 5 samples (17% of the total number of samples) contained residues of acetamiprid and cypermethrin, and out of 5 contaminated samples, only one sample contained residue of acetamiprid, which was above the maximum residue limits set by European Union (EU-MRLs). While, in the case of eggplant, out of 30 analyzed samples, 4 samples (13% of the total number of samples) contained residues of cypermethrin and acetamiprid, where 1 sample contained residue of acetamiprid, which was above the EU-MRLs. None of the sample was found contaminated with thiram and lambda-cyhalothrin residues for both of the analyzed vegetables. This study reflects the overall scenario of pesticide residues remain in country bean and eggplant collected from different markets of Barishal district, which will help the consumer and policy makers to be aware of their health and safety.
