Abstract
The study was conducted to detect and quantify the residue of seven commonly used organophosphorus pesticides (acephate, chlorpyrifos, quinalphos, diazinon, malathion, dimethoate and fenitrothion) in eggplant and tomato samples collected from local market of commercially grown four different regions viz. Bogura, Narsingdi, Jeshore and Cumilla for the comparison between the detected residue level with maximum residue limit (MRL) set by European Union. A total of 80 analyzed samples of eggplant and tomato, 21.25% of the total number of samples contaminated with acephate, chlorpyrifos, fenitrothion and diazinon residues which were above the EU-MRLs. Out of 40 analyzed samples of eggplant, 11 samples were contaminated with acephate, diazinon fenitrothion and chlorpyrifos residues. All of the contaminated samples (27.5% of the total number of samples) had chlorpyrifos (0.02-0.046), acephate (0.017-0-0.39), diazinon (0.11-0.47) and fenitrothion (0.20) residues which were above the EU-MRLs. The eggplant samples collected from Jeshore and Narsingdi received more pesticides than Cumilla and Bogura regions. In case of 40 analyzed samples of tomato, 6 samples (15% of the total number of samples) had chlorpyrifos (0.27-0.43), diazinon (0.25) and fenitrothion (0.10) residues which were above EU-MRLs. Malathion, quinalphos and dimethoate residues were not found in any of the tested samples which might be applied at recommended doses. Asian Australas. J. Food Saf. Secur. 2021, 5 (1), 27-31
Highlights
Vegetables grown in Bangladesh are very popular to consumers
The analytical results of the eggplant and tomato for the detection of pesticide residue are summarized in Tables 1 and 2
The results revealed that 11 samples (27.50% of the total number of samples) contaminated with fenitrothion (0.20), diazinon (0.11-0.47), acephate (0.017-0-0.39) and chlorpyrifos (0.02-0.046) residues which were above the maximum residue limit (MRL) provided by European Union
Summary
Vegetables grown in Bangladesh are very popular to consumers. These are conceded as a source of many nutrients, including potassium, dietary fiber, vitamin A, and vitamin C. One potential drawback associated with a shift toward more intensive vegetable production is the common reliance of most vegetable producers on heavy application of pesticide (Hossain et al, 2000). Pesticide residue in food has become a consumers safety issue. Very little references are available on the presence of pesticides in vegetables in Bangladesh
