“…In this study, imidacloprid residues were removed in the range of 65.16 -66.29% from grapes during washing with tap water and it is inferred that there is a strong correlation between water solubility (600 mg L -1 ) and removal of imidacloprid (Malhat et al 2021). Crushing/homogenisation does not impact residues, but it speeds up processes like hydrolysis and releases isolated enzymes, acids from the cuticle layer more quickly, reducing residues in the juice.…”

“…The residues found were less than the FSSAI and EU MRLs of 1.0 mg/kg. A negligible amount of systemic insecticides might be absorbed by pulp or fruits (Malhat et al 2021). In the case of juice preparation, pasteurisation (80 o C for 10 minutes) was led to the loss of imidacloprid residue (10.49%) and it might be due to evaporation, hydrolysis, or thermal destruction during heating.…”

Field and laboratory experiments were conducted to study the effect of simple decontamination methods and processing on imidacloprid, dimethoate, and emamectin benzoate residues in grapes and their processed products using Liquid-Chromatograph Mass Spectrometer validated method. Among the decontamination methods evaluated, sodium chloride (2%) solution was found effective and contributed to the reduction of imidacloprid (77.55%), dimethoate (83.27%) and emamectin benzoate (77.28%) residues in mature grapes. Grapes were processed into various products viz., fresh juice, squash and raisin as per standard effective steps for each product. Based on decontamination experiment ndings, washing with sodium chloride (2%) solution was included as an additional step in the standard protocol and has resulted in substantial removal of surface residues of selected insecticides. The processing factor calculated was less than one for all the products.

Pesticides have evolved into a crucial instrument in agriculture’s evolution as a plant protection agent for increasing food output. Moreover, pesticides contribute significantly by preventing a number of terrible diseases. However, both occupational and environmental pesticide exposure can lead to a number of health issues in people. It has been noted that pesticide exposures are becoming more and more associated with immune system suppression, hormone disruption, lowered intellect, abnormalities in reproduction, and cancer. Because of the great demand for farm produce and their lack of awareness of the hazardous consequences of pesticide residues in food, some farmers do not wait long enough for the residues to wash off after spraying before harvesting. As a result, residues in food products have appeared as a result of increased pesticide use in agriculture. Some of the primary tactics for reducing human exposure to pesticides are pesticide safety, regulation of pesticide usage, appropriate application technology, and integrated pest management.

“…The phytochemical properties of imidacloprid viz., water solubility (0.61 g/L at 20 °C), vapor pressure (3 x 10 -12 mmHg at 20 °C), octanol/water partition coefficient (Kow) (pH 7 -0.57 at 21 °C) and Henry's constant (1.7 x 10 -10 Pa•m 3 /mol) (Pesticide Properties DataBase, 2022). Imidacloprid residues in crops like mango, grapes, okra, potato, cucumber, strawberry, apple and soil have been quantified using Liquid chromatography with tandem mass spectrometry (LC-MS/MS), High-performance liquid chromatography (HPLC), Gas chromatography mass spectrometry (GC-MS) and Liquid chromatography with mass spectrometry (LC-MS) (Malhat et al, 2021;Hendawi et al, 2018;Majed et al, 2021;Mohapatra et al, 2012;Sahoo et al, 2012). While previous research estimated imidacloprid residues on different crops, no systematic study has been carried out on the dissipation kinetics, decontamination and risk assessment of imidacloprid in bitter gourd.…”

Imidacloprid is a broad-spectrum neonicotinoid class insecticide with systemic action, widely used on vegetables in India for the management of sucking insect pests. The overall pesticide usage profile in gourds growing districts of Tamil Nadu showed that imidacloprid as the most commonly used insecticide. The present study aimed to develop and validate an analytical approach for detecting imidacloprid and 6-chloronicotinic acid residues in bitter gourd fruit, juice and soil using LC-EI-MS (liquid chromatography coupled with electron ionization mass spectrometry) was undertaken. The persistence pattern, effect of household processing and risk assessment of imidacloprid on bitter gourd was studied by conducting field trials at single and double doses of 20 and 40 g a.i ha-1. Calibration curves showed a good linear relationship (r2>0.99) with the concentrations (0.0025–0.5 µg mL-1) of imidacloprid and 6-chloronicotinic acid. The limit of detection and quantification of the method were 0.008 and 0.025 mg kg-1, respectively. Accuracy of imidacloprid and 6-chloronicotinic acid residue recovery was in the range of 88–101 per cent with RSD of less than six per cent in all the matrices of bitter gourd. Initial deposits of imidacloprid at 20 and 40 g a.i ha-1 were 0.68 and 1.25 mg kg-1 and the residues persisted up to 10 and 15 days with their respective half-lives of 2.51 and 3.13 days. Simple decontamination techniques showed 33 to 80 per cent reduction of residues in samples collected up to 10 days after treatment. The estimated RQ was less than one indicating the level of risk to the consumer is negligible.
