“…Method validation was performed by checking the linearity, ME, LOQ, accuracy (indicated by recovery), and precision. 33 The linearity was constructed by plotting concentrations against the peak area, and appropriate linearity and coefficients over reasonable concentration ranges were achieved. All regression data for oxine-copper in cucumber and watermelon were obtained, as shown in Table 2 .…”

“…The chromatograms of the test pesticide standard were compared to the untreated tomato matrix sample, and no interference peak was observed, therefore establishing the specificity of the analytical method. The ability of the analytical method to detect a particular analyte from the mixture is referred to as selectivity or specificity of the method (Sharma et al 2021). It is defined as the ability of an analytical method to measure the desired analyte in a complex mixture (Chandran & Singh, 2007).…”

“…The availability of an appropriate analytical method and its reliability and robustness to address the required parameters of testing are the prerequisites to perform residue studies (Sharma et al, 2021). Method validation is a tool for determining the suitability of an analytical method for use in the laboratory for the analysis of a specific sample (Hoskins, 1961).…”

“…The capacity of a procedure to provide outcomes that are proportionate to the concentration of the variables is referred to as linearity (AOAC, 1993). The linearity approach assesses sensitivity at various dosages (Sharma et al, 2021). For precision and accuracy, the samples were spiked with all the test pesticides at 0.05, 0.10, 0.25, 0.50, and 1.00 mg/kg fortification levels and replicated five times (Dubey et al, 2021).…”

Pesticide residue in food commodities is a serious concern in relation to consumer safety and also the most significant barrier in the trade of food commodities. The dissipation pattern of four insecticides, namely novaluron, λ‐cyhalothrin, imidacloprid, and fenazaquin, was evaluated on tomato fruits and cropped soil. The residues were extracted using the QuEChERS analytical method and quantized using a gas chromatograph with electron capture detector, gas chromatograph mass spectrometer, and high‐performance liquid chromatography with photo diode array detector. The analytical method was validated using parameters like recovery, linearity, accuracy, matrix effect, and specificity, with limit of detection and limit of quantitation established to be 0.01 and 0.05 mg/kg, respectively, for all the pesticides. The average initial deposits (samples collected after 2 h of application) at the recommended dose of novaluron, λ‐cyhalothrin, imidacloprid, and fenazaquin were 0.593, 0.293, 0.227, and 0.431 mg/kg on tomato fruits, respectively, and were below the limit of quantification in soil. The pre‐harvest interval of 17, 8, 1, and 13 days was suggested for novaluron, λ‐cyhalothrin, imidacloprid, and fenazaquin on tomato, respectively. Risk assessment studies revealed that all pesticides under study are safe and do not pose any threat to humans as theoretical maximum dietary intake is less than the maximum permissible intake and acceptable daily intake.

“…The effectiveness of the washing procedure relies on the chemicals used, their mechanisms of action, their solubility in water, and when they are harvested [8]. Sonali sharma [9] reported that washing of fipronil and imidacloprid residues in chilli with microwave cooking reduced residues from 93%-100%. But however these methods may results in loss of vitamins etc.…”

Farmers that cultivate tomatoes use imidacloprid to combat sucking bugs even while the fruits are being harvested so that they can maintain a five- to six-time harvest. Decontaminating tomato fruits before eating is absolutely necessary due to the insecticide's slow dissipation rate and the fact that residues last in vegetables for 15–25 days. The quality of fruit has been compromised and cannot be used in salads, despite the fact that various heat procedures are effective in removing imidacloprid residue. Therefore, a study was conducted to assess the effectiveness of common electrolytes, namely NaCl and NaHCO3, and their combinations, on imidacloprid removal from tomato fruits. Fruits and washing solutions were extracted for imidacloprid residue and determined using the UFLC-PDA besides optimizing the concentration and period of decontamination or washing without dietary risk. Results indicates that the washing of the fruits with NaCl @ 1, 2 and 3% solutions for 10 minutes are efficient (98-100% removal) in decontaminating to below hazard quotient when sprayed with recommended 20 g ai/ha. Whereas, the NaHCO3 or its combination with NaCl 1% for 10 minutes was found to be efficient (92-100%) in decontaminating the fruits when sprayed with 40 g ai/ha. Increasing the decontamination period beyond 10 minutes increased the residue load on fruits to above hazard quotient and was above 1.0 when NaCl was used. Study suggests the washing of tomato fruits with 2%NaHCO3 or 1%NaCl+2% NaHCO3 for 10 minutes is the efficient decontamination way and to ensure safety to the consumers.
