Summary: A sensitive and reliable quantitative LC-MS/MS method has been developed and validated for simultaneous determination of a wide range of veterinary drug and pesticide residues and mycotoxins in bovine urine. The method fulfills the requirements under Regulation 2021/808/EC and can be used for routine analysis of bovine urine samples.

Summary: This study developed a LC-HRMS method for screening, quantification, and identification of veterinary drugs and pesticide residues in pig muscle. The method involved extraction of tissues with acidic methanol/water with EDTA, followed by solid phase extraction. The extracts were analyzed using a MaXis Q-TOF mass spectrometer, with criteria established for screening and identification.

Summary: A simple and rapid analytical method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed for simultaneous determination of pesticide residues and mycotoxins in apples. Through optimization of microwave-assisted extraction, the method demonstrated superiority in extraction efficiency and rapidity compared to the QuEChERS sample preparation method.

Summary: Bees are exposed to environmental contaminants during foraging, resulting in the transfer of pollutants to beehive products. A study analyzed 109 samples of honey, pollen, and beebread, and found various pesticide residues. Despite the presence of pesticide residues, the risk assessment for human and bee health is not a major concern.

Summary: A validated multi-residue method using LC-MS/MS and GC-MS/MS for analyzing various pesticides in raisins was conducted according to DG SANTE guidelines. Results showed the presence of multiple pesticides in conventional samples, while no analyzed pesticides were detected in samples from organic farming. The study highlights the need for official controls on pesticide residues in processed samples, particularly on high consumption dried fruits like raisins.

Summary: The study assessed the occurrence and quantification of pesticides in gherkins cultivated in Turkey, finding that a proportion of samples contained pesticide residues, some of which were not approved in the EU. Multiple pesticide residues were detected in some samples, with some exceeding the maximum residue levels.

Summary: A novel and accurate method for the determination of folpet and phthalimide residues in tea has been developed, using solid-phase extraction combined with gas chromatography-tandem mass spectrometry. The method proposes converting all folpet to phthalimide prior to sample extraction and purification, and utilizes an isotopic internal standard for quantification. The study confirms the accurate determination of phthalimide content and its conversion to folpet content.

Summary: A freeze-dried bovine muscle-certified reference material (CRM), called BOTS-1, containing residues of commonly used veterinary drugs, was produced and certified. Liquid chromatography tandem mass spectrometry (LC-MS/MS) methods were used for value assignment, along with isotope dilution and standard addition approaches. Data from multiple organizations were used for value assignment. Results were obtained through an international inter-laboratory comparison. Primary standards were characterized using quantitative NMR (1H-qNMR). The certified mass fractions of the veterinary drug residues were reported with expanded uncertainties.

Summary: This study analyzed 222 pesticide active substances in 90 samples of seven different vegetables and fruits using LC-MS/MS and GC-MS/MS technology. The results showed that active substances were found in 39% of the samples, with 7% exceeding the maximum residue levels. Peeling and washing with hot water were found to be the most effective strategies for removing pesticide residues.

Summary: The study developed a two-dimensional high performance liquid chromatography tandem mass spectrometry method for analyzing multiple food contaminants and residues in cereals, including various mycotoxins and pesticides. Validation results showed good linearity, recovery rates, and stability for most analytes, but some analysis results were unsatisfactory for certain substances.

Summary: In recent decades, changes in human behavior and new technologies have introduced thousands of new compounds called contaminants of emerging concern (CEC) into the environment. These CEC compounds have been detected in various environmental compartments such as soil, surface water, air, and groundwater. This study used statistical analysis by self-organizing maps (SOM) to evaluate the trends of CEC in urban groundwater systems, and found that atrazine, hexazinone, simazine, and other compounds were frequently detected in groundwater samples. Caffeine was also commonly detected in the samples, likely due to a local population habit of consuming a hot drink made of yerba mate.

Summary: The growth of the field of medicinal herbs and the increased demand for plant-derived products have raised concerns about consumer health safety. Evaluation of mycotoxins and pesticide residues in medicinal herbs showed about thirty percent contamination. Data emphasized the importance of implementing international monitoring in these matrices.
