DETERMINATION OF CYPERMETHRIN RESIDUE IN VEGETABLES (TOMATO, OKRA AND EGGPLANT) BY SPECTROPHOTOMETRIC METHOD

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.
