“…The m-PFC method greatly shortens the purification time and improves the sample preparation efficiency for the analysis of pesticide residues. Using QuEChERS extraction-based automatic m-PFC method, carboxyl-functionalized multi-walled carbon nanotubes (MWCNTs-COOH) were filled in the m-PFC column as an adsorbent with good adsorption performance (Song et al, 2022), which can integrate cleaning and filtering into a single run before injection into the detection instrument. In another study, Dong et al (2021) used the m-PFC method of complex adsorbents to adsorb and purify tea samples and evaluated the purification effect of the chromatographic column based on the removal rate of interfering components.…”

Due to its rich health benefits and unique cultural charm, tea drinking is increasingly popular with the public in modern society. The safety of tea is the top priority that affects the development of tea industry and the health of consumers. During the process of tea growth, pesticides are used to prevent the invasion of pests and diseases with maintaining high quality and stable yield. Because hot water brewing is the traditional way of tea consumption, water is the main carrier for pesticide residues in tea into human body accompanied by potential risks. In this review, pesticides used in tea gardens are divided into two categories according to their solubility, among which water-soluble pesticides pose a greater risk. We summarized the methods of the sample pretreatment and detection of pesticide residues and expounded the migration patterns and influencing factors of tea throughout the process of growth, processing, storage, and consumption. Moreover, the toxicity and safety of pesticide residues and diseases caused by human intake were analyzed. The risk assessment and traceability of pesticide residues in tea were carried out, and potential eco-friendly improvement strategies were proposed. The review is expected to provide a valuable reference for reducing risks of pesticide residues in tea and ensuring the safety of tea consumption.

The present study describes an efficient analytical method for analyzing apple pesticide residues. This novel approach employs ultrasound-assisted cleaning (UAC), solid-phase microextraction (SPME), and gas chromatography/mass spectrometry (GC-MS). A fiber coating with carbon nanomaterials (CNMs) was used for the extraction process. The methodology underwent extraction process optimization and analytical method validation. Moreover, its applicability for detecting pesticides in apples was evaluated. The validation showed satisfactory results with linearity coefficients greater than 0.99 (R2 > 0.99) and linear working ranges from 0.5 ng·g−1 to 300.0 ng·g−1. The limits of detection and quantification (LODs and LOQs) ranged from 0.1 ng·g−1 to 0.3 ng·g−1 and from 0.5 ng·g−1 to 0.7 ng·g−1, respectively. The calculated recovery values ranged from 79% to 98%. The precision presented a relative standard deviation (RSD) lower than 14%. The validated method was applied to apple samples acquired from different markets and fruit stands in Belo Horizonte, Minas Gerais, Brazil. Organophosphate pesticides typically used in Brazilian apple production areas were detected in some samples. This study demonstrates the utility of UAC and CNM microextraction as an effective and highly efficient approach for analyzing pesticides in apples.

“…Regarding extraction techniques, several protocols for the determination of pesticides can be found in literature such as liquid-liquid extraction [21], solid-phase extraction [22], solid-phase micro-extraction SPME [15], matrix solidphase dispersion [22], pressurized liquid extraction [23], dispersive liquid-liquid microextraction (DLLME) [24], QuEChERS [25,26], and automated multi-plug filtration cleanup [27].…”

“…Additionally, most pesticides are volatile and thermostable, so GC had become the main separation technique applied to multi-residue analysis [7,28]. Nevertheless, liquid chromatography has been successfully applied to pesticide multi-residue analysis, mainly for high polar, non-volatile, and/or thermally labile compounds [26,27,29]. For both GC and LC techniques, detectors based on MS are predominantly employed [26][27][28][29].…”

In this work, a cost-effective gas chromatography-mass spectrometry method was validated for the analysis of twenty-five pesticide residues in herbs and infusions using a quick, easy, cheap, effective, rugged, and safe procedure or a dispersive liquid-liquid microextraction method, respectively. Figures of merit of the method showed good accordance with current guidelines. From the 58 herb samples studied (pertaining to 20 different species), 80% presented at least one detectable pesticide, with 62% of them above the maximum residual level. Results showed that pesticide residues from naturally contaminated herbs were not transferred at a significant rate to the herbal infusions. When a control assay was conducted by spiking a blank herb sample with a large amount of each pesticide (7 mg/L) 15 analytes were detected below the limit of quantification in the infusion.
