Summary: This study evaluated the burden of As, Hg, Pb, and Cd in 314 marine fishes from the Amazon Coast. The results showed higher Hg concentrations in reef-associated fish compared to demersal fish. The study also found correlations between As, Pb, and Cd, suggesting similar dispersion properties and bioaccumulation homology. The concentrations of As exceeded guidelines and legal limits in a majority of the examined species, while Cd, Hg, and Pb levels were generally low. The estimated daily intake of iAs, Hg, and Pb were found to pose potential non-carcinogenic health risks.

Summary: The aim of this study was to determine the background concentration, soil contamination level, and human health risk of potentially toxic elements in Arica commune. Samples were collected from rural and urban areas, and environmental indices and US EPA model were used for analysis. Results showed varying degrees of soil contamination, with children being at higher risk compared to adults. However, no carcinogenic risk was found in the analysis of available concentrations for both adults and children.

Summary: Coal-fired industrial boilers are a significant source of trace metals emissions in China. A high-resolution emission inventory for Hg, As, Cd, Cr, and Pb in 2017 was established based on data from over 61,000 CFIBs. The study found that emissions were concentrated in northern and eastern regions, with seasonal variations and an overall decrease in emissions due to control measures.

Summary: Apple residues, banana peel, eggshell, potato peel, and sweet potato peel were tested as biosorbents to remove top priority contaminants (As, Cd, Hg, and Pb) from contaminated waters. The results showed that these biosorbents were able to significantly reduce the levels of contaminants in water within 3 hours, especially for Hg. The pH had no notable effect on the removal, but ionic strength influenced the removal of Cd and Hg.

Summary: This study aimed to investigate the combined ecotoxicological effects of Cd, Pb, Zn, Hg and regulation mechanisms in Solanum nigrum L. The co-exposure of these heavy metals hindered the transformation of Cd, Zn, and Hg into non-available forms. Each metal individually induced oxidative damage to S. nigrum L., but their combination further enhanced ecological toxicity. Internal regulation, such as hyperaccumulation of Cd in plant roots and immobilization in the cell wall and vacuole, and external regulation involving changes in soil microbial communities, played important roles in detoxification pathways.

Summary: This study presents the development of a microplate spectrophotometric method for determination of indole-3-carbinol in dietary supplements. The method is simple, rapid, and suitable for multi-sample analysis, making it a potential approach for quality control of indole-3-carbinol in dietary supplements.

Summary: In this study, the molecular structural characteristics and spectroscopic properties of complexes formed by substituting the central atom of heme with mercury, cadmium, lead, chromium, or arsenic were investigated using computational methods. The results showed that these complexes were stable and exhibited unique spectroscopic characteristics. Interestingly, the binding capacity of the heme ligand to lead was found to be significantly higher compared to iron and the other heavy metals studied. Additionally, the complex in which iron was replaced by cadmium displayed the highest chemical stability. These findings provide important insights for future pollution control programs and the enrichment of heavy metals using heme ligands.

Summary: This study analyzed the speciation, bioavailability, and human health risk of toxic heavy metals in urban soils of a heavy industrial city in NE China. The results showed that concentrations of Arsenic (As), Mercury (Hg), Lead (Pb), and Cadmium (Cd) in the soil all exceeded the background value of the study area. Mercury displayed the highest pollution level, followed by Cd, Pb, and As. The study also found that using bioavailable fraction for health risk assessment provided more reliable results.

Summary: Seaweed is considered a functional food with high nutritional value in Western countries, but human activities have led to an increase in pollutants like toxic metals and nitrates in edible algae. Legislation is necessary to regulate the content of toxic metals and nitrates in edible algae.

Summary: This study investigates the toxicity of nine trace metals to a rotifer under different salinity conditions, finding higher toxicity at low salinity and an intensification in single metal toxicity with increasing application factor and decreasing salinity. Lead was identified as the most toxic metal, while arsenic treatment showed enhanced growth for Proales similis. Treatments T1 and T2 were found to be the most toxic and often induced a synergistic effect.

Summary: This study analyzed the association between heavy metal accumulation in infants and the risk of orofacial cleft (OFC) in Bandung Regency. The results showed significant differences in the concentration of heavy metals Hg, Pb, and Cd, and an increase in Pb and Cd in infant blood was significantly associated with the risk of OFC.

Summary: This study aimed to determine the impact of different cooking methods on heavy metal residues in eggs. The analysis found that the dry-frying method was most effective in reducing heavy metal levels, while other cooking methods had little impact on the residues of other heavy metals. All heavy metal residues were within acceptable thresholds.

Summary: This study successfully prepared nanostructured MoS2 on cotton fabric, demonstrating its efficient adsorption capability for heavy metal ions within a short period of time. The adsorption process followed a Langmuir model, but was better described by a Sips equation indicating low energy adsorption dispersion. The hybrid structure of cotton and MoS2 showed exceptional adsorption efficiency for toxic heavy metal ions.
