Abstract
A sensitive Spectrophotometric method was initiated for the determination of
pesticide residue of cypermethrin, from 75 collected samples of different
vegetables (tomato, okra and eggplant). A total of 75 samples (25 samples of
tomato, 25 samples of okra and 25 samples of eggplant) were collected from five
different locations (Kawran Bazar, Jatrabari, Shanti Nagar, Shyamoli and Mirpur1)
in Dhaka city. The proposed methods have been successfully applied for the
determination of cypermethrin in collected samples. Among the 25 analyzed
samples of tomato, 2 samples (8% of the total number of samples) contained
residues of cypermethrin, where one sample contained above the maximum
residue limits (MRLs) and one was below MRLs. Out of 25 samples of okra, 2
samples (8% of the total number of samples) contained residues cypermethrin,
where both were contained below the maximum residue limits (MRLs). Among
the 25 analyzed samples of eggplant, 3 samples (12% of the total number of
samples) contained residues of cypermethrin, where one sample contained above
the maximum residue limits (MRLs) and two were below MRLs. This study
reflects the overall cypermethrinresidue remain in tomato, okra and
eggplantcollected from different markets of Dhaka city, which will help the
consumer to be aware of their health and safety.
