“…It is also easy to use and has a short detection time, and 30-40 preweighed samples can be processed in one hour. Te QuEChERS approach, however, has a poor purifying capacity, which might cause contamination issues and impair measurement accuracy [94]. It has always been challenging to prepare samples for the investigation of trace chemicals in problematic matrices [95].…”

In Ethiopia, using pesticides to manage pests in the growing of fruits and vegetables is a standard practice. Various classes of pesticides have been approved to combat pests, but the majority of those in use now are outdated broad-spectrum insecticides with significant residual effects on crops of freshly eaten fruits and vegetables. This review reveals that Ethiopia’s assessment of the residual pesticide level in fruits and vegetables has been lacking. According to the reviewed literature, crops that are often treated with pesticides in many countries have significant residual pesticide levels. However, Ethiopia has not adequately reported on this issue. Furthermore, due to a lack of knowledge regarding the impact of pesticide residues on human health, Ethiopians frequently use pesticides improperly to control pests in fruits and vegetables. The majority of consumers eat their fruits and vegetables unprocessed, without washing or cooking them first. To reduce the risk of pesticide residues in fruits and vegetables for consumer safety and to battle the health effects of toxic chemicals in humans, monitoring pesticide residues and raising awareness about the adverse effects of pesticides on humans are urgently needed. Before they may be registered and sold, pesticide residues in fruits and vegetables as well as in the environment must also undergo proper testing and evaluation. New pesticide generations that have fewer side effects on fruits and vegetables must also be developed. By washing, peeling, canning, or boiling fruits and vegetables before consumption, the detrimental effects of pesticide residues on human health can be minimized.

“…Sun et al (2022) used a combined sorbent package consisting of MWNTs-OH and PSA for the extraction and purification of 57 pesticides to remove the interferences of pigment in Lonicerae japonicae flower buds and improve the quantitative accuracy in pesticide residues analysis (15). Zhao and Shi used non-porous boron nitride nanorods (p-BNNRs) as clean-up sorbents to eliminate matrix interference in QuEChERS analysis method for the detection of five neonicotinoid pesticide residues in goji berries (16).…”

Previously published studies indicate that tea (Camellia sinensis) contains essential oils, flavonoids, phenolics, lipids, natural pigments, sugars, and oligosaccharides. These essential biomolecules in Camellia sinensis cause serious problems in the determination of pesticide residues. High amount of co extractives can exhibit chromatographic characteristics similar to some pesticides, which may cause serious matrix effects and significant interference in mass spectrometry analysis. In this study, we compared four polymeric resins as clean-up sorbents for the determination of 216 pesticide residues in tea by a high performance liquid chromatography triple quadrupole mass spectrometry. styrene-divynilbenzene (Diaion HP20), Polyamide 6, Polyvinylpolypyrrolidone (PPVP), and Amberlite XAD 7 were used as clean-up sorbents instead of PSA. However,to evaluate the effectiveness of the adsorbents, recovery studies were carried out using these adsorbents. In addition, GC-MS analysis was also performed to see the ability of these adsorbents to remove co-extracts. According to the recovery results, when the acceptable limit was accepted as 60-140%, it was determined that the resin that gave the best results with 170 pesticides was polyamide. Diaion was the second resin with 166 pesticides, while XAD, PSA which was used as control group and PPVP were determined as the third, fourth, and fifth resins with very close values of 159, 155, and 152 pesticides, respectively. According to GC-MS total ion analysis, it was observed that PSA gave the chromatogram with the least co- extract, while it was observed that PSA was the worst adsorbent in removing caffeine, one of the main bioactive compounds in tea. XAD-7 and Polyamide were found to be the best adsorbents in removing caffeine.

“…Up to now, researchers have proposed versatile sample pretreatment methods to extract targets from different samples, such as solvent extraction, solid phase extraction (SPE), the QuEChERS method (the Quick, Easy, Cheap, Effective, Rugged, and Safe method), etc. [8,[39][40][41][42]. Nanomaterials could be used for the extraction and enrichment of targets in complex matrices due to their small size, large specific surface area, and adjustable surface groups.…”

Imidacloprid (IMI) has been applied in agricultural production to prevent pests. It is vital to detect IMI residues with high sensitivity for food safety. In general, nanomaterials have driven the development of highly sensitive sensing platforms owing to their unique physical and chemical properties. Nanomaterials play important roles in the construction of high-performance sensors, mainly through sample pretreatment and purification, recognition molecules immobilization, signal amplification, and providing catalytic active sites. This review addresses the advances in IMI sensors based on the combination of nanomaterials and various analytical techniques. The design principles and performance of different chromatographic, electrochemical, and fabricated optical sensors coupled with nanomaterials are discussed. Finally, the challenges and prospects of sensors based on nanomaterials for IMI analysis have also been incorporated.
