Multiple pesticide residue determination in major vegetables purchased from Gazipur district of Bangladesh

Abstract

The present study was initiated to detect and quantify pesticide residues in three selected major vegetables (hyacinth bean, cauliflower and yard long bean) collected from 5 local markets of Gazipur district of Bangladesh. The vegetable samples were prepared by Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction technique and analyzed by Gas Chromatography (GC) equipped with Flame Thermionic Detector (FTD). In this study, 45 vegetable samples were analyzed. Out of 15 samples of hyacinth bean, 2 samples (13% of the total samples) contained pesticide residues above MRL and the remaining samples did not contain any detectable pesticide residues. In the instance of cauliflower, 2 samples (13% of the total number of samples) contained pesticide residues above MRL, while the remaining samples had no detectable pesticide residues. Pesticide residues with levels exceeding MRL were found and measured in 3 samples (20% of the total number of samples) from 15 yard long bean samples. From remnant samples, no pesticide residue was detected. This study depicts the overall scenario of pesticide contamination in vegetables specially in hyacinth bean, cauliflower and yard long bean available in the local markets of Gazipur city, Bangladesh. As a result, it is important to intensify routine pesticide residue monitoring in commercially cultivated vegetables. Asian Australas. J. Food Saf. Secur. 2022, 6 (2), 57-64

“…Over the last decades, many studies have been conducted to determine the pesticide residue in vegetable production in Bangladesh [10] , [101] , [102] , [23] , [4] , [5] , [53] , [6] , [63] , [64] , [82] , [90] . But the data were either on one pesticide group, a single pesticide, or a combination of pesticides in a single vegetable or a group of vegetables.…”

Monitoring of pesticide residues in yard long bean collected from Mymensingh district of Bangladesh

“…Gas Chromatography coupled with flame thermionic detector is widely used for the quantification of pesticide residues in vegetables, fruits (Alam et al, 2022;Rahman et al, 2021;Prodhan et al, 2021;Ahmed et al, 2021;, fish and dry fish (Hoque et al, 2021;Prodhan et al, 2018a;2010;2009), sugercane (Kabir et al, 2007), betel leaf and water (Prodhan et al, 2021a;2021b), as they are very much sensitive for the quantification of organophosphorus pesticides. Up until now, several research works have been conducted for the quantification of pesticide residues in vegetables in Bangladesh (Tasnim et al, 2022;Parvin et al, 2021;Hasan et al, 2021;Habib et al, 2021;Nahar et al, 2020;Islam et al, 2021;2019a;Prodhan et al, 2022;2018b;2018c;Hossain et al, 2014;Islam et al, 2014;Kabir et al, 2008;2008a). However, more research work is needed to find out the actual scenario of pesticide residues remain in vegetables in a specific area of Bangladesh.…”

Analysis of organophosphorus pesticide residues in selected vegetables purchased from Narsingdi district of Bangladesh using QuEChERS Extraction

“…In Bangladesh, a limited analytical method was developed using LC-MS/MS (Prodhan et al, 2022), but the majority of pesticide residue measurements are made using Gas Chromatography in conjunction with a flame thermionic detector in fruits and vegetables (Rahman et al, 2021;Prodhan et al, 2021;Ahmed et al, 2021;, fish and dry fish (Prodhan et al, 2018a;2010;2009;Hoque et al, 2021), sugarcane (Kabir et al, 2007), betel leaf and water (Prodhan et al, 2021a;2021b), because they are very much sensitive for the analysis of organophosphorus pesticides. Several studies have been done for the quantification of pesticide residues in vegetables in Bangladesh (Tasnim et al, 2022;Hossain et al, 2014;Alam et al, 2022;Parvin et al, 2021;Hasan et al, 2021;Islam et al, 2014;Kabir et al, 2008;2008a;Habib et al, 2021;Nahar et al, 2020;2019a;Prodhan et al, 2018b;2018c). However, additional study is needed to know the actual situation of pesticide residues remaining in vegetables in a specific region of Bangladesh.…”
