Summary: In this study, 36 traditional medicines were evaluated using T-XRF and PBET methods, and potentially toxic trace elements were detected. By comparing the ADI values of each medicine with the USEPA RfD limits, it was found that the risks of these medicines were within acceptable range. In summary, this study provides new insights into the health risks of potentially toxic and essential trace elements in traditional medicines.

Summary: Studies have shown significant differences in the bioaccessibility of PTE in soil across different size fractions, with a general trend of higher bioaccessibility in finer size fractions. The relationship between bioaccessibility and soil size fraction varies for different elements, suggesting the need for consensus on methods to determine PTE bioaccessibility for more accurate human health risk assessment.

Summary: The introduction of complementary foods is a crucial step in the transition to solid foods for infants, but these foods may contain potentially harmful toxic elements. Understanding the bioaccessibility of these elements is essential for assessing the potential risks to infants. Standardized assessment methods and regulatory guidelines have been established, but there are still research opportunities and significant knowledge gaps.

Summary: Plantago subulata is a facultative serpentinophyte with predominantly ultramafic distribution in Serbia and Montenegro. The study showed that high concentrations of specific elements were found in the plant and soil samples from abandoned mining sites, indicating the accumulation potential of this species. The plant acted as an indicator species for elements like Zn, Ni, and Cr, and showed exclusion and root sequestration as tolerance strategies for elements like Cd and Pb.

Summary: This study investigated the deposited and dissolved bioaccessibility of potentially toxic elements (PTEs) in different sizes of particulate matter (PM) in a Chinese megacity. The results showed that fine PM had higher dissolved bioaccessible fraction (DBF) of certain elements compared to coarse PM. The presence of oxide/silicate compounds from coal combustion was found to lower the DBF of certain elements in fine particle sizes. Inhalation health risks were highest in particulate sizes below 0.43 μm and between 2.1-3.3 μm, with cancer risk exceeding the threshold value. Uncertainty analysis revealed that total concentrations and DBF of certain elements in the particle size segment below 0.43 μm had a greater influence on the probabilistic risk.

Summary: This study used one-step modification of fly ash to generate modified fly ash with high adsorption capacity for removing heavy metals from aqueous solutions. The modified fly ash showed a destroyed surface structure, 12 times increase in specific surface area, and successful adsorption of metal ions. The adsorption effects were influenced by pH, ionic strength, and co-existing cations. The adsorption mechanisms were ion exchange, electrostatic attraction, and complexation. The modified fly ash also showed the ability to release absorbed heavy metal ions in organisms and aquatic environments.

Summary: The knowledge gained from this study on the electrochemical behavior of diclofenac is crucial for the development of a voltammetric sensor for detecting the drug in water samples. Different carbon-based electrodes were examined, and the optimal voltammetric procedure for determining diclofenac concentration was established. The results showed that the glassy carbon electrode and the smaller surface of the screen-printed carbon electrode immersed in solution had the lowest detection limits.

Summary: The determination of the authenticity of extra virgin olive oils (EVOOs) has gained increasing interest, especially in Italy, which has the highest number of Protected Designation of Origin (PDO) oils in Europe. This study focused on using the inorganic content and electrochemical properties as markers to identify the region of origin and plant species of EVOOs. The results showed that the inorganic composition can be a useful marker for the geographical origin of EVOOs, while the voltammetric analysis can effectively distinguish the plant species of origin. This method could also be used to monitor the conservation status of the oils.

Summary: This work evaluates the air quality of two industrial cities in Italy, Turin and Biella, and identifies the main sources of pollution and its evolution over 15 years. The analysis reveals that urban activities and soil/road dust resuspension are the main contributors to metal pollution. Although Biella has lower pollution levels than Turin, the daily average concentration of PM10 frequently exceeds the European limit value.

Summary: A novel photoelectrochemical biosensor based on gold nanoparticles and specific structures was developed for highly sensitive detection of mercury ion. The multiple sandwich structures hindered electron supply and light harvesting, resulting in a weakened PEC signal, while the specific structures extinguished the PEC signal, enabling quantitative detection of Hg2+. The sensor exhibited high selectivity and stability, with potential applications in environmental detection, biological analysis, and medical research.

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.
