Summary: ETAAS is a well-known method for determining trace elements in natural objects, especially promising for pharmaceutical analysis of medicinal plant raw materials. A new unified ETAAS technique has been developed for determining cadmium, lead, and arsenic in solutions obtained after acid decomposition of plant raw materials under microwave heating conditions. The technique was validated for specificity, accuracy, precision, repeatability, linearity, range, and robustness, and can be recommended for determining ecotoxicants accumulation in wild-growing and cultivated medicinal plants.

Summary: Urbanization and industrialization have resulted in high levels of heavy metal pollution around the world, posing a threat to ecosystems. In this study, the concentrations of arsenic, cadmium, copper, and lead were analyzed in eggshells of Common Cranes nesting in north-eastern Germany. The results showed that only copper and lead were present in the eggshell samples, and their concentrations were not considered toxic to birds. The study also found a significant decrease in trace element concentrations over the study period. While the ban of leaded gasoline and restrictions on heavy metal-based biocontrol products have contributed to this decrease, increasing agricultural areas have led to a gradual increase in copper levels. Additionally, the study revealed that heavy metals do not accumulate in the circulatory systems of adult cranes over time. This study is the first to assess heavy metal contamination in Common Cranes and highlights the potential of crane's eggshells as a bioindicator for monitoring environmental pollution.

Summary: A novel spectrophotometric method has been developed for the analysis of cadmium, cobalt, copper, iron, and lead. The method involves microwave-assisted in-situ complexation of metal ions with a ligand formed by the reaction of phenol, sodium nitrite, and streptomycin in an acidic medium. The method was successfully applied to the analysis of various real samples, including pharmaceuticals and industrially important products such as batteries. Optimum pH values and reagent concentrations were determined for each metal, and the method showed good sensitivity and detection limits for each metal.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
