Special Issue Information

Dear Colleagues,

The establishment of simple, sensitive, and efficient tools for the detection of ultratrace levels of contaminants in food matrices is necessary to ensure the safety of consumers. New varieties of pesticides continue to flood the market, requiring lower and lower detection limits for pesticides and therefore more sensitive, accurate, and efficient detection technology to achieve improved detection sensitivity and diversification of detection methods, shorten the response time, and improve the degree of automation of the instrument and the field detection capabilities.

To improve detection efficiency, detect potential threats in the form of pesticide residues in a targeted manner, and clarify the health risk, new, faster, easy to handle, environmentally friendly, and cheap methods are continuously needed thanks to the growing demands for legislative requirements in the area of food safety. Extraction methods should be generic to allow the detection of pesticides with different physicochemical properties. Thus, in addition to targeted pesticides, the scope of this analysis can expand if high-resolution mass spectrometry is used, performing targeted, nontargeted, and unknown analyses, including the detection of metabolites or unexpected pesticides.

The aim of this Special Issue is to provide insights into the progress and challenges in the development of analytical methods for pesticide residues in various food, plant, and nutraceutical samples. In addition to conventional targeted analysis and dissipation studies, suspect screening and unknown analysis are also welcome, applying high-resolution mass spectrometry or other suitable analytical techniques. Authors are kindly invited to contribute to this Special Issue, which I believe will have a significant impact in the field.

The production of nutraceuticals is a growing trend, as many consumers consider them an important part of the modern active lifestyle. Others rely on the use of nutraceuticals instead of prescribing pharmaceuticals to improve their health more naturally. One of the major concerns in the nutraceutical industry is the potential presence of contaminants. Even low concentrations of contaminant residues can be harmful, so analytical methods that are sensitive at ultratrace levels are needed. Dispersive liquid–liquid microextraction method combined with fast gas chromatography and mass spectrometry was developed for the inspection of pesticide residues in Carmelite drops. The most suitable recoveries are presented when the alcohol content is fixed at 20% in Carmelite drops. The method was validated; the linearity, limits of detection/quantification, the method accuracy and precision were obtained. The complex nutraceutical matrix causes significant complications in quantitative analysis; therefore, the main target of the work was placed on studying the effects of the matrix on the correct expression of the resulting concentration of contaminants in different types of samples. An in-depth study of matrix factors was carried out, and its relationship with the content of potential interferents from the medicinal products as well as other components added during the drops’ production was discussed. Related medicinal plant-derived nutraceuticals were tested, the method was applied for real-life samples, and positive findings are herein reported. Full article

This study investigated the degradation characteristics and conducted a risk assessment of four pesticides (Diniconazole, Dinotefuran, Metconazole, and Tebuconazole) in the leaves and roots of radish. Radish was cultivated in two greenhouse fields, and samples were collected at 0, 1, 2, 3, 5, 7, and 10 days after pesticide application. Sample analysis was performed using LC-MS/MS, and the recovery rates ranged from 70.1% to 118.6%. The biological half-life of Diniconazole was found to be 6.2 days (leaf and root), Dinotefuran was 5.3 days (leaf) and 4.6 days (root), Metconazole was 9.3 days (leaf) and 3.2 days (root), and Tebuconazole was 8.0 days (leaf) and 5.1 days (root). After comparing the maximum residue limits (MRL) of each pesticide in Korea with the residues during the pre-harvest interval (PHI), Diniconazole showed a Hazard quotient (HQ) exceeding 1, indicating potential risks for true consumers. Furthermore, Tebuconazole showed an HQ of 0.3 or higher, indicating a significant level of risk. Full article
