Summary: Analysis of 52 coal ash samples from individual households revealed correlations between the concentrations of studied elements, pH and coal grades. The maximum concentrations of arsenic, cadmium, lead and thallium in the ash samples were 50,900, 43,500, 128,900, and 6660 μg/kg, respectively. The results were compared with published data for industrial ash.

Summary: Lead and cadmium in non-mineralized raw milk samples were determined using dispersive solid-phase extraction with magnetic restricted access carbon nanotubes (M-RACNTs) followed by flame atomic absorption spectrometry analysis. M-RACNTs with magnetite nanoparticles and a chemically crosslinked bovine serum albumin (BSA) external layer efficiently captured the metals and excluded proteins from the milk, and could be easily separated using a neodymium magnet. The method was validated and proved to be simple, fast, sensitive, and selective, with a determination coefficient of 0.998 and a limit of quantification of 10 μg/L for both Pb2+ and Cd2+ ions, below the maximum residue limits in Brazil.

Summary: A novel IDBD reactor coupled with ETV was established for arsenic determination, investigating the evolution mechanisms of arsenic species using XPS. DBDA atomizes arsenic nanoparticles while DBDT traps and releases arsenic oxides, enhancing sensitivity and precision in seafood sample analysis. The method shows potential for rapid arsenic analysis based on direct solid sampling ETV instrumentation.

Summary: The elemental composition of the body's calcified tissues may reflect the environmental exposure of the population to heavy metals. This study assessed the elemental composition of maxillary bone samples from residents of two cities with different levels of lead and cadmium pollution. The results showed that residents from the more polluted city had higher levels of lead and cadmium, as well as higher levels of other essential metals.

Summary: The determination of heavy metals in drinking water is crucial for quality assessment and pipeline corrosion detection. This study developed a simple, cost-effective method based on cloud point extraction for preconcentration and determination of iron, lead, and cadmium, with a 20-fold reduction in detection limit. Results demonstrate high accuracy and reproducibility of this method for the analysis of iron, lead, and cadmium in water samples by FAAS.

Summary: A novel liquid phase microextraction method was developed for the simultaneous determination of lead and cadmium in different samples. The method utilized effervescent tablets to improve extraction efficiency, achieving good linear calibration range from 0.06 to 10.0 mg L-1 (Pb) and 0.02 to 1.50 mg L-1 (Cd). The study demonstrated that the proposed method is applicable for accurate determination of lead and cadmium in water and canned food samples.

Summary: This study assessed the levels of lead, cadmium, and tin in offals of chicken, cattle, and pig, as well as in canned food. The results showed that offal samples met the safety standards for human consumption, while some canned food samples exceeded the maximum level of tin set by Codex Alimentarius, posing a potential risk to consumers.

Summary: The disruption of copper homeostasis may lead to neurodegenerative disorders, highlighting the importance of understanding the role of Cu+ in physiological and pathological processes. A new near-infrared fluorescent turn-on probe (NPCu) was developed based on a Cu+-mediated benzylic ether bond cleavage mechanism, showing high selectivity and sensitivity towards Cu+ and successfully applied for bioimaging of Cu+ in living cells.

Summary: This research successfully achieved the simultaneous analysis of Cu(II), Cd(II), and Ni(II) ions in water samples by using a novel organic co-precipitant CCMBATT in combination with carrier element-free co-precipitation technique. The highest efficiency in terms of heavy metal recovery was achieved by optimizing factors such as solution pH, co-precipitant concentration, and sample volume.
