Summary: Soil is a major recipient of contaminants, including organochlorine pesticides, despite being banned in the EU. A GC-MS/MS method was developed and applied to soil samples, revealing the presence of dieldrin. The subsequent health risk assessment showed negligible non-carcinogenic risk and tolerable carcinogenic risk, indicating the importance of continuous monitoring for persistent chemical residues in soil.

Summary: Pesticide residues in food have been a food safety issue for consumers. This study developed a validated method using QuEChERS and GC-MS/MS to detect fluopyram residues in fruits and vegetables. The results showed good recovery rates and low matrix effects for fluopyram in all food matrices. Market investigation revealed 19 positive samples with one tomato sample exceeding the EU MRL. Field trials on cowpea showed acceptable levels of fluopyram residues and dietary risk assessment indicated it was safe. This study's detection method provides better monitoring of fluopyram residues in food.

Summary: Craft beers produced by small local breweries are gaining popularity worldwide due to their unique composition and taste. However, the study found that most dark craft beers in Poland and the Czech Republic contain polycyclic aromatic hydrocarbons (PAHs), with levels varying between the two countries. Additionally, acrylamide was detected in all beers, with higher levels in Polish beers. Regular consumption of dark beers with high acrylamide levels poses a serious health risk.

Summary: This study investigated the presence of PFAS in plant-based food products and found multiple PFAS compounds in cereal-based products. Perfluorooctanoic acid (PFOA) was the most frequently detected compound, while perfluorobutanoic acid (PFBA) was the predominant PFAS in cereal-based products. These compounds likely originate from soil-root-shoot interactions and the ability of PFAS to interfere with proteins. Therefore, cereal-based products should be considered in future dietary exposure assessments.

Summary: This study aimed to investigate pesticide residues, polycyclic aromatic hydrocarbon (PAH) levels, and 5-hydroxymethylfurfural (HMF) content in selected European honeys. The results showed that the most frequently detected pesticide was 4,4'-DDD, found in 14 honey samples. Slovakian rapeseed honey was the most polluted due to the presence of eight pesticides. Organophosphorus pesticides (OPs) were detected in all samples, with at least one sample exceeding the acceptable limit. PAHs were detected in most samples. Some honeys exceeded the established HMF levels, while others met the requirements.

Summary: The aim of this study was to evaluate the concentration of HMF, furfural, PAHs, and pesticide residues in Polish bee products and assess their cancer risk. Sample preparation and analysis techniques were used to determine the levels of these compounds. The results showed that bee bread from the northeast part of Poland had the highest furfural content and samples from the same region had higher levels of HMF. PAHs were detected in the samples, but only benzo[a]anthracene and chrysene were found. Imidacloprid and acetamiprid were found in bee bread, while clothianidin was detected in honey samples. The study concluded that regular consumption of bee bread and pollen could pose a severe health threat due to the high concentration of PAHs and excessive recommended consumption dose.

Summary: This study investigates the effects of consuming fermented red beetroot juice on the profile and content of PFASs in the blood plasma and urine of volunteers. The results show that there is a downward trend in the perfluorocarboxylic acids and an upward trend in the perfluoroalkane sulfonates after consuming the juice. The intake of fermented red beetroot juice also leads to significant changes in hematological parameters, such as a decrease in MCV, platelet concentration, MPV, P-LCR, and hematocrit, and an increase in MCHC. However, no significant changes are observed in blood biochemistry, except for a decrease in total cholesterol and LDL-C levels.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.

Summary: This work proposes a rapid and sensitive spectroscopic method for detecting melamine in food products using rare-earth Terbium-doped Graphene Quantum Dots (Tb-GQDs) synthesized by microwave and simple chemical conjugation methods. The synthesized Tb-GQDs show a spherical shape with a size of approximately 6 nm and a quantum yield of 52%. The maximum detection limit for melamine concentration in milk and milk products is found to be 0.31 μM. The dual emitting Tb-GQDs provide a sensitive and effective platform for real-time detection of melamine in food samples, particularly in milk, and show promising potential in the food industry.
