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.
