Abstract:
A study was conducted to analyze pesticide residues in two common vegetables (cabbage and
lady‟s finger) collected from five local markets of Cumilla district during January 2018 to
May 2018. The collected samples were carried to the Pesticide Analytical Laboratory,
Entomology Division of Bangladesh Agricultural Research Institute (BARI), Gazipur on
the same sampling day. The collected samples were analyzed using Quick, Easy, Cheap,
Effective, Rugged and Safe (QuEChERS) extraction technique and Gas Chromatography
(GC) coupled with Flame Thermionic Detector (FTD) for the determination of pesticide
residues in 40 samples of cabbage and 40 samples of lady‟s finger. Among the 40
analyzed samples of cabbage, 5 samples (12.5% of the total number of samples) contained
residues of dimethoate and diazinon where 1 sample contained multiple residues and 5
samples contained residue above the maximum residue limits (MRLs). Out of 40 samples of
lady‟s finger, 4 samples (10% of the total number of samples) contained residues of
dimethoate and diazinon, where 2 samples contained multiple residues and 4 sample
contained pesticide residues above MRL. This study reflects the overall scenario of pesticide
residue remain in cabbage and lady‟s finger collected from local markets of Cumilla district,
which will help the consumer to be aware of their health and safety.
