Abstract
In this work, we monitored 432 pesticide residues in 39 tomato samples (cherry tomato) obtained from local markets in Souss Massa region-Morocco. We used a QuEChERS combined with LC-MS/MS and GC-MS/MS, and the method was validated based on SANTE 11312/2021 guideline. The limits of quantification (LOQ) obtained for most of the pesticides analyzed are at the limit with default EU MRLs or well below other EU MRLs. Recoveries (between 70 and 120%) and RSDs (≤20%) are satisfactory for more than 95% of the analytes at spiking level of 0.01 mg/kg and more than 97% at 0.1 mg/kg. The results indicated that 22 out of 39 tomato samples are positives and the most of our samples had levels lower than the maximum residue levels (MRLs) with average concentrations between 0.011 and 0.156 mg/kg. The most found pesticides were azoxystrobin and difenoconazole in tomato (7 samples). Only buprofezin (0.095 mg/kg) was found above the EU MRLs (0.01 mg/kg). Also, banned pesticides namely benalaxyl, spirodiclofen and imidacloprid have been detected. The results of our study confirm the previous findings and gives insights on the occurrence of different pesticides in tomato samples from Souss Massa region-Morocco.

Abstract
Abstract
Background
The ever increasing pests and diseases occurring during vegetable crop production is a challenge for agronomists and farmers. One of the practices to avoid or control the attack of the causal agents is the use of pesticides, including herbicides, insecticides nematicides, and molluscicides. However, the use of these products can result in the presence of harmful residues in horticultural crops, which cause several human diseases such as weakened immunity, splenomegaly, renal failure, hepatitis, respiratory diseases, and cancer. Therefore, it was necessary to find safe and effective techniques to detect these residues in horticultural crops and to monitor food security.
Main body
The review discusses the use of conventional methods to detect pesticide residues on horticultural crops, explain the sensitivity of nanoparticle markers to detect a variety of pesticides, discuss the different methods of rapid test paper technology and highlight recent research on rapid test paper detection of pesticides.
Conclusions
The methodologies discussed in the current review can be used in a certain situation, and the variety of methods enable detection of different types of pesticides in the environment. Notably, the highly sensitive immunoassay, which offers the advantages of being low cost, highly specific and sensitive, allows it to be integrated into many detection fields to accurately detect pesticides.

Abstract
Every year, after grape harvesting, high quantities of vine-canes are generated. Due to the high amount of bioactive compounds present in this woody material, several studies reported their potential to be used in different sustainable applications. However, before employing vine-canes in this kind of products, their safety needs to be assessed. A robust method for identification and quantification of 30 environmental contaminants (12 organochloride pesticides (OCPs), 6 organophosphorus pesticides (OPPs), 5 polychlorinated biphenyls (PCBs) and 7 brominated flame retardants (BFRs)) in vine-canes was developed. For that, the extraction and clean-up procedures were optimized, namely the vine-canes size, the QuEChERS (quick, easy, cheap, effective, rugged and safe) composition and the amount of carbon used in the dispersive-solid phase extraction (d-SPE). Suitable analytical parameters were obtained: linearity (r2) >0.99 for all the studied compounds and for the solvent and matrix-matched standards; relative standard deviation (RSD) below 14%; and mean recoveries for two spiking levels (10 and 20 μg/kg) between 75 and 103%, excepting for the PCBs that ranged between 59 and 105%. The limit of detection (LOD) and quantification (LOQ) ranged between 0.38 and 1.09 and 1.26 to 3.64 μg/kg, respectively. Regarding the analysis of 19 vine-cane samples, corresponding to four different varieties (Touriga Nacional, Tinta Roriz, Alvarinho, and Loureiro) collected in four different years in the North of Portugal, five contaminants (aldrin, 2,2-bis(4-chlorophenyl)-1,1-dichloroethylene (p,p'-DDE), α-hexachlorocyclohexane (α-HCH), 2,4,4'-trichlorobiphenyl (PCB28), and 2,2',4,5,5'-pentachlorobiphenyl (PCB101)) were detected. However, only α-HCH (5.85 ± 0.32 to 5.99 ± 0.25 μg/kg) and aldrin (2.44 ± 0.15 μg/kg) were quantified above the LOQ. The screening of environmental contaminants in vine-canes is essential to waste valorization, especially if the goal is to apply them in products for human consumption.

Abstract
Eugenol compounds are widely used in the circulation and transportation of fresh aquatic products because of their good anesthetic effects. However, some studies have shown that eugenol compounds are potential carcinogens. Therefore, in order to ensure the edible safety of aquatic products, eugenol compounds in aquatic products need to be screened quickly. A method for determination of six eugenol residues in aquatic products was established by multiplug filtration cleanup (m-PFC), combined with gas chromatography-Orbitrap mass spectrometry (Orbitrap GC-MS). Samples were ultrasonically extracted with acetonitrile, and the extracts were frozen at −18°C for 1 h, then purified with the m-PFC column, and detected by Orbitrap GC-MS in full scan mode. The results showed the linear relationships for six eugenols were good in the range of 0.001–0.1 μg/mL, and the correlation coefficients (R2) were above 0.9950. The limits of detection (LODs) were 2–10 μg/kg, and the limits of quantitation (LOQs) were 5–20 μg/kg. The average recoveries at the spiked levels of 5–200 μg/kg were in the range of 76.4%–105.1%, with relative standard deviations (RSDs) of 1.2%–7.5%. Eighty aquatic products were detected by this method, of which only eugenol was detected in 12 samples, and eugenol and isoeugenol were detected in two samples at the same time. The other eugenol compounds were not detected in any sample. The detection rate of positive samples was 17.5%. The method is simple, accurate, and suitable for the rapid screening of eugenol compounds in aquatic products.

Abstract
Food analysis is a tremendously broad field that is constantly evolving. New methods have emerged to increase productivity, such as modern miniaturized and robotic analytical techniques. In this paper, a micro-solid-phase extraction system (µ-SPE) for clean-up was combined with a robotic autosampler to yield ready-to-analyze extracts. The system was evaluated for its applicability in routine laboratories. The new, automated, high-throughput µ-SPE clean-up method was applied to acetonitrile extracts and was developed for the analysis of pesticide residues in cereals by gas chromatography-Orbitrap mass spectrometry (GC-Orbitrap-MS). The µ-SPE clean-up efficiency was demonstrated in the removal of matrix-interfering components and in the recovery of pesticides. The sorbent bed mixture consisted of magnesium sulfate, primary-secondary amine, C18, and CarbonX, and effectively retained matrix components without loss of target analytes. Analysis of five types of cereals (barley, oat, rice, rye, and wheat) by GC-Orbitrap-MS showed that the method removed more than 70% of matrix components. The clean-up method was validated for 170 pesticides in rye, 159 pesticides in wheat, 142 pesticides in barley, 130 pesticides in oat, and 127 pesticides in rice. Spike recovery values were 70-120% for all pesticides and the repeatability, calculated as the relative standard deviation, was less than 20%. The limits of quantitation achieved were 0.005 mg kg-1 for almost all analytes, ensuring compliance with the maximum residue limits.

Abstract
A wide variety of pesticides have been used in agriculture to increase the yield, quality and extend the storage life of crops. However, the use of pesticide has been increased now a day due to the ever-increasing population and rapid urbanization. The continuous uses of these pesticides have resulted in contamination of the environment, crops and also caused potential risk to human health. For this reason, strict regulations are developed and regulated to monitor these compounds. To date, several techniques have been developed for the extraction and detection of pesticides, from traditional to advanced detection techniques. The present study delineates a comprehensive up to date overview of the available traditional methods (gas chromatography and high-performance liquid chromatography coupled with various detector) to advanced pre-treatment (polystyrene-coated magnetic nanoparticle) and detection (sensor development and nanotechnology) techniques used in the analysis of pesticides residue in various fruits and vegetables. Also, categorization of pesticides and its toxicity have been discussed.

Abstract
INTRODUCTION Pesticides are organic compounds widely used in modern agriculture, being relevant for helping plantations and increasing food production. The banana, a fruit with oriental origin, stands out for being widely produced in tropical and subtropical regions which, like other matrices, is susceptible to pest action. This review aims to evaluate the presence of pesticides in bananas according to Brazilian, European and Codex legislation. METHODS Four databases, ScienceDirect, SciELO, PubMed and Springer, were used to find relevant articles in the literature addressing methods for the determination of pesticide residues in bananas using the terms "banana", "chromatography", "pesticides" and "determination". The search stages included reading abstracts and titles, reading the full text, extracting data and analyzing data from eligible articles. The search was restricted to original research articles published in English from 2008 to 2018. RESULTS 404 articles were found from the initial research, with only 15 studies being considered eligible for this review. Mass spectrometry is the most widely used detection technique. 5 articles were seen to use a multiresidue method to analyze only bananas (pulp), and from these, only 2 studies used methods to analyze the pulp and peel. The articles analyzed 172 samples, with 59.3% of these being conducted in Europe, 32.5% being conducted in Asia and only 8.1% in South America. A total of 79.1%, 32.4% and 42.6% of samples were unsatisfactory according to the Brazilian, European and Codex legislation, respectively, with these samples being contaminated with pesticide residues. CONCLUSION This review presents the scarcity of articles aimed at identifying pesticide residues in bananas and the urgency of checking the quality of the fruit that reaches the population. The MRLs allowed by different legislations have clear divergences that do not ensure the lowest concentration values that guarantee consumer safety.

These tips are referred to as "QuEChERS Tips". Using loosely contained sorbent, dispersive solid phase extraction (dSPE) cleanup was performed with the QuEChERS Tips and automation. The main advantage of the QuEChERS Tips is that they are readily automated because this dSPE method does not require centrifugation. High recoveries (70-117%) and good reproducibilities (<12%) are shown for over 200 pesticides using automated QuEChERS Tips and GC-MS in various sample matrices.
