“…According to world food ethics (which are based on USA food rules) [ 28 ], the agricultural crops contaminated with residual pesticides (C1, P1, C2, P2) are certainly harmful to human health [ 29 ]. To simulate the detection of pesticides on fruits, apples were spiked with 10 −2 M standard solution containing C1, P1, C2 and P2.…”

Trace detection of common pesticide residue is necessary to assure safety of fruit and vegetables, given that the potential health risk to consumers is attributed to the contamination of the sources. A simple, rapid and effective means of finding the residue is however required for household purposes. In recent years, the technique in association with surface-enhanced Raman scattering (SERS) has been well developed in particular for trace detection of target molecules. Herein, gold nanoparticles (Au NPs) were integrated with sol-gel spin-coated Zirconia nanofibers (ZrO2 NFs) as a chemically stable substrate and used for SERS application. The morphologies of Au NPs/ZrO2 NFs were adjusted by the precursor concentrations (_X, X = 0.05–0.5 M) and the effect of SERS on Au NPs/ZrO2 NFs_X was evaluated by different Raman laser wavelengths using rhodamine 6G as the probe molecule at low concentrations. The target pesticides, phosmet (P1), carbaryl (C1), permethrin (P2) and cypermethrin (C2) were thereafter tested and analyzed. Au NPs/ZrO2 NFs_0.3 exhibited an enhancement factor of 2.1 × 107, which could detect P1, C1, P2 and C2 at the concentrations down to 10−8, 10−7, 10−7 and 10−6 M, respectively. High selectivity to the organophosphates was also found. As the pesticides were dip-coated on an apple and then measured on the diluted juice containing sliced apple peels, the characteristic peaks of each pesticide could be clearly identified. It is thus promising to use NPs/ZrO2 NFs_0.3 as a novel SERS-active substrate for trace detection of pesticide residue upon, for example, fruits or vegetables.

“…All the this section is fully explained in our previous research [21] starting from the preparation of the standard solutions of the 86 pesticides then, the determination of pesticides residues using GC-MS/MS following SANCO guidelines [22] and the fitness for purpose of analytical methods [23], it is worth mentioning that the preparation of the sample was including collecting of tomato from the local vegetables market of Al-Rass province, Al-Qassim region, Saudi Arabia, during the summer season in 2017, samples were cutting mixing, and homogenization, then, sample Extraction/partitioning and dispersive solid-phase extraction (SPE) cleanup was processed using an Agilent Bond Elut QuEChERS dispersive SPE, finally the extracts were capped and shaken by vortex mixer thoroughly and transferred to the GC auto-sampler for GC-MS/MS analysis using Thermo Scientific™ TSQ™ 8000 Evo Triple Quadrupole GC-MS/MS pesticide analyzer system and the same thermal program and the TSQ 8000 system which automatically optimized acquisition windows and set instrument duty cycle using timed-selected reaction monitoring (t-SRM) for maximum sensitivity. After that, Identification of compounds was based on comparison of their mass spectra with those recorded in the (NIST/EPA/NIH Mass Spectral Library -NIST MS Search Program v 2.0g, 2011).…”

“…The parameters for the 86 pesticides analyzed by GC-MS/MS are fully illustrated in our previous research [21].The maximum residual limit (MRL) of these pesticide residues is recommended by the European Union standards [22,24]. The samples of tomatoes have followed different methods of home preparation handling and processing: firstly, samples were collected from the market with no special processing, secondly, samples were rinsed with running tap water for 30-45 sec, thirdly, samples were boiled in tap water and finally samples were soakedin5%solution of commercial acetic acid as well as 2% sodium chloride aqueous solution.…”

This study was carried out to develop and apply a quick, yet efficient, analytical method for simultaneous determination of the residues of the 86 pesticides repeatedly detected in food commodity in Al-Rass province of Al-Qassim Region, Saudi Arabia. The suggested method is based on QuEChERS extraction procedures based on acetonitrile followed by a dispersive solid-phase extraction (d-SPE) with primarysecondary amine (PSA) and bulk of carbograph for clean-up, was applied prior to GC-MS/MS analysis, focusing in particular on tomato crops. The second aim of the study was to measure the levels of some heavy metals using FAAS technique, particularly, Cu, Cd, Zn, Fe and Pb. The third aim was to evaluate the effectiveness of some common household-type preparations and handling procedures for tomato on reducing the levels of the detected pesticide residues as well as the heavy metals. The current findings could provide that the proper home preparation of tomato samples, in particular, soaking in 2% sodium chloride solution and soaking in commercial 5% acetic acid has led to effective elimination of the pesticide ethion from those samples. However, results have shown that there was no significant effect on the levels of heavy metals in the investigated tomato samples after applying the common types of household treatments.

“…The levels of pesticide residues in vegetables can be affected by the ways of food processing, such as tap‐water cleaning, sodium hypochlorite solution cleaning, hot‐water blanching, and salting (Abdalla et al, 2017; Bonnechère et al, 2012; Yang et al, 2012). However, the effect of these methods is not ideal, and may even bring secondary pollution.…”

The effect of ultrasound, ozone, and their combination treatment on the removal of two common pesticides (trichlorfon and phoxim) in pak choi samples was studied in this work. The results showed that both ultrasound and ozone treatment alone can significantly remove trichlorfon and phoxim residues in pak choi (>90%), but they reduced the quality of pak choi (such as vitamin C and color). Ultrasound and ozone had a synergistic effect on the removal of pesticide residues in pak choi. The synergistic effect of combined treatment was evaluated from the perspective of pesticide removal speed, and found that their combination significantly accelerated the removal of pesticides. Compared with ultrasound or ozone alone, the removal rate constant of trichlorfon by the combined treatment increased by 121% and 347%, and that of phoxim increased by 159% and 367%, respectively. In addition, the combined treatment of ultrasound and ozone can well maintain the vitamin C and color of pak choi while removing pesticides. Therefore, the combined treatment of ultrasound and ozone can be used as an effective cleaning method to remove pesticide residues in vegetables.Practical applicationsReducing pesticide residues in vegetables is of great significance to human health, and how to maintain the quality of vegetables as much as possible while removing pesticides is a key issue. In this study, the combination of ultrasound and ozone significantly accelerated the removal of pesticides, and retained the vitamin C and color of pak choi well. Therefore, the combined application of ultrasound and ozone has the potential to be an industrial cleaning method for removing pesticide residues in fruits and vegetables without compromising quality.
