Summary: Large quantities of phosphogypsum from Tunisian industrial waste have a negative impact on the hydrographic network and pose a risk to soil contamination and human health due to toxicity in the food chain. A study conducted in the M'Dhilla Basin of southwestern Tunisia revealed high levels of trace metal element pollution, particularly with Cd, Sr, and Zn, which exacerbate environmental problems and increase the carcinogenic health risks for inhabitants in the mining basin.

Summary: This study compared the concentration, distribution, source identification, and risk assessment of PAHs in soils from surrounding areas of an abandoned industrial district and an ecological village in Zhejiang Province, China. The results showed that industrial areas had higher levels of PAHs originating from fossil fuel burning and vehicle emissions, while rural areas had lower levels mainly from biomass burning and vehicle emission. Adults might face higher potential health risk than children, and the overall ecological risk of soil PAH pollution was low in rural areas.

Summary: Contamination of potentially toxic elements (PTEs) in children's park soils in 12 major cities of Pakistan poses potential health risks to the local population. The concentration of nickel exceeded permissible limits, while other PTEs were within acceptable levels. The contamination sources include industrial emissions, fossil fuel combustion, vehicular emissions, wastewater irrigation, solid waste disposal, and natural soil parent materials. Mitigation measures and strict enforcement of environmental regulations are recommended.

Summary: The present study investigated the heavy metal pollution in soils from an area with intensive industrial activities in South China. The results showed that the concentrations of Cd, As, Hg, Cu, Ni, Pb, and Zn were higher than background levels in both surface and subsurface soils. The primary sources of heavy metals were identified as agriculture, industry, transportation, and nature. Anthropogenic activities significantly influenced the spatial distribution of heavy metals in soils. The health risks of heavy metal exposure via different routes were found to be at an unacceptable level, with higher risks for adults compared to children. Therefore, monitoring heavy metal pollution in soils in rapidly developing areas, such as South China, is of great importance.

Summary: Transition metals have essential roles in biological tissues, but some, like cadmium, can be highly toxic. Disturbances in metal balance caused by micronutrient deficiency, pollution or genetic factors can lead to malfunction and diseases. This study used synchrotron X-ray fluorescence microscopy and mice with altered antioxidant enzyme functions to demonstrate the potential of SXRF as a powerful tool for studying biologically relevant metal balance in the pancreas and liver of mice models with disturbed glucose homeostasis.

Summary: X-ray fluorescence analysis is useful for detecting long half-life radionuclides, especially uranium isotopes that are difficult to detect by radiation measurements. This study proposes an energy-dispersive X-ray fluorescence analysis method for rapid screening of uranium-contaminated substances, and verifies the linear relationship between uranium concentration and signal intensity.

Summary: Protein aggregation is a characteristic of severe neurodegenerative disorders, and metal ions play a significant role in this process. Through analysis, it was found that the zinc content in cells increased threefold and the potassium enrichment increased tenfold, which may be a result of cellular stress response. Although the ion content in aggregate-containing cells differs from non-aggregate-containing cells, there is no difference in ion content at the location of intracellular inclusion bodies. These results suggest that changes in ion concentration are not exclusively linked to the formation of specific proteins.

Summary: This study assessed the air quality in urban parks and industrial areas using leaves from Callistemon citrininus and Acacia melanoxylon trees. The results showed variations in metal concentrations in the leaves, with Ca, K, and Mg found in higher amounts. Acacia melanoxylon seemed to perform better as a biomonitor. The contamination factor analysis revealed that Cu, Zn, Fe, and Al were the most contaminating metals in industrial areas, while Cu, Pb, Ba, and Mn were the most contaminating metals in park areas.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
