Pesticides in vegetable production in Bangladesh: A systemic review of contamination levels and associated health risks in the last decade

Toxicology Reports, Journal Year: 2023, Volume and Issue: 11, P. 199 - 211

Published: Sept. 9, 2023

This paper reviewed the published data on levels of different pesticide residues in vegetables (tomato, eggplant, beans, gourds, cauliflower, cabbage, cucumber, potato, carrot, onion, red chilli, amaranth, lady's finger, spinach, coriander, and lettuce) from Bangladesh last decade. Vegetable production has increased tremendously (37.63%) compared to decades, along with its use. The most observed groups used vegetable were organophosphorus, pyrethroids, carbamate, organochlorine, nereistoxin analogue group, neonicotinoids. More specifically, chlorpyrifos, dimethoate, diazinon, malathion pesticides. than 29% samples (1577) contaminated residue; among (458), cases (73%) exceeded maximum residue limits (MRLs). pesticide-contaminated cucumber (51%), tomato (41%), cauliflower (31%), miscellaneous (36%), eggplant (29%), beans (23%), cabbage (18%), gourds (16%). Among samples, above MRL (100%), (92), (78%), (73%), (69%), (62%), (50%), (50%) (p < 0.05). It was also that a single often multiple pesticides, farmers did not follow proper withdrawal period while using Hazard quotation (HQ>1) adolescents adults tomato, lettuce, coriander. There no health risk (HQ<1) okra. highest acute chronic HQ (aHQ, cHQ) for cypermethrin (bean) (aHQ=255, cHQ= 510) (aHQ=131, cHQ=263). these pesticides harmed air, soil, water, non-target organisms. Nevertheless, review will help government develop policies reduce use raise people's awareness harmful effects.

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

Asian-Australasian Journal of Bioscience and Biotechnology, Journal Year: 2023, Volume and Issue: 8(1), P. 8 - 16

Published: April 30, 2023

The farmers of our country mostly depend on chemical pesticides for crop protection due to the scarcity competent pesticide alternatives and enough knowledge safe pest management. As a result, there is great possibility remain residues in harvested crops. Keeping this view, study was conducted analyze organophosphorus yard long bean collected from five local markets Mymensingh district Bangladesh. samples were carried Pesticide Analytical Laboratory, Entomology Division Bangladesh Agricultural Research Institute (BARI), Gazipur same sampling day. analyzed using Quick, Easy, Cheap, Effective, Rugged Safe (QuEChERS) extraction technique Gas Chromatography (GC) coupled with Flame Thermionic Detector (FTD). Among 30 bean, 3 (10% total samples) contained residue quinalphos, which 2 quinalphos above MRL. This reflects overall scenario city. Therefore, monitoring vegetables should be strengthened.

Determination of pre harvest interval for selected pesticides in hyacinth bean in the agro-climatic conditions of Bangladesh

Asian-Australasian Journal of Food Safety and Security, Journal Year: 2023, Volume and Issue: 7(1), P. 47 - 55

Published: May 29, 2023

The present study was conducted to determine the pre harvest interval of chlorpyrifos and quinalphos in hyacinth bean agro-climatic condition Bangladesh ensure safe food for consumers. A supervised field trial undertaken experimental Entomology Division BARI, Gazipur selected pesticides (chlorpyrifos quinalphos) were sprayed with recommended dose (1.5 ml/L water). samples collected at 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 12 days after spray (DAS). extracted cleaned up using modified Quick, Easy, Cheap, Effective, Rugged Safe (QuEChERS) extraction technique residues determined by Gas Chromatography (GC) coupled Flame Thermionic Detector (FTD). residue detected upto 8 DAS (0.027 mg/Kg) a level above EU-MRL, 9 DAS, no detected. So, PHI set DAS. On other hand, which EU-MRL (0.02 mg/kg). At remained 0.009 mg/Kg, below EU-MRL. Asian Australas. J. Food Saf. Secur. 2023, 7 (1), 47-55

Development of analytical method for fipronil determination using Gas Chromatography Triple Quadrupole Mass Spectrometry

Asian-Australasian Journal of Food Safety and Security, Journal Year: 2023, Volume and Issue: 7(1), P. 40 - 46

Published: May 29, 2023

The application of fipronil for the control insect pests different crops is increasing day by day. As a result, it inevitable to remain residues in treated crops. Therefore, an urgent need develop analytical method quantification fipronil. Keeping this view, study was initiated and optimize residue using Gas Chromatography triple quadrupole Mass Spectrometry (GC-MS/MS). A number experiments has been conducted select parent ion precusor based on these findings, determination GC-MS/MS developed. linearity developed very good 0.999. optimization MS/MS parameters done properly through direct injection 100 ug/L standard solution Asian Australas.

Degradation of selected organophosphorus pesticide residues and their pre harvest interval determination in hyacinth bean grown commercially in Bangladesh

Asian-Australasian Journal of Bioscience and Biotechnology, Journal Year: 2023, Volume and Issue: 8(2), P. 30 - 37

Published: Aug. 29, 2023

The consumers are very much concerned about food safety. To ensure safe for the consumers, it is essential to follow pre harvest interval (PHI) of pesticides. Therefore, in order ascertain pre-harvest fenitrothion and diazinon hyacinth bean environmental conditions Bangladesh, this study was started. chosen organophosphorus insecticides (fenitrothion diazinon) were sprayed with recommended dose (1.5 ml/L water) a field trial at Entomology Division BARI, Gazipur. At 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 12 days after spray (DAS), samples taken. Gas chromatography (GC) Flame Thermionic Detector (FTD) used quantify residues prepared using modified Quick, Easy, Cheap, Effective, Rugged Safe (QuEChERS) extraction method. Fenitrothion residue found up 8 DAS, 7 DAS (0.018 mg/Kg), level above MRL. 0.007 mg/kg, which below Pre-harvest determined no 9 DAS. Diazinon MRL (0.016 mg/Kg). as 10 found. Asian Australas. J.
