Summary: Chronic exposure to excessive environmental fluoride has led to the emergence of fluorosis as a major public health problem worldwide. This study found significant differences in the gut microbiota and metabolome of patients with coal-burning-induced endemic fluorosis, suggesting that alterations in these factors play a crucial role in regulating disease susceptibility and multi-organ damage after excessive fluoride exposure.

Summary: This study investigated the migration and emission behavior of arsenic and selenium in a circulating fluidized bed power plant equipped with fabric filter and wet flue gas desulfurization system. The results showed arsenic was mainly enriched in bottom ash and fly ash, while selenium was mainly captured by fly ash. Limestone injection into furnace promoted the retention of arsenic and selenium in ash residues.

Summary: This study investigated the associations and risks of trace elements related to skin and liver damage induced by arsenic exposure. Results showed that a decrease in Se was a risk factor for arsenic-induced skin and liver damage, while increases in Al and V were risk factors for skin and liver damage. Se and Al were found to have certain diagnostic values for skin damage, Se for liver damage, and the combination of Se and Al enhanced the diagnostic value for skin damage.

Summary: Evidence from epidemiological studies suggests that chronic arsenic exposure may be associated with a higher incidence of hypertension. This study investigated the relationship between arsenic exposure and blood pressure in a population of arsenicosis patients. The results showed that arsenic exposure increased the risk of hypertension and wide pulse pressure, primarily due to an increase in systolic blood pressure and pulse pressure. Higher levels of monomethylated arsenicals (MMA) and trivalent arsenic (As3+) exposure were associated with a greater risk of hypertension and wide pulse pressure.

Summary: This study investigated the clay samples from coal-bearing strata in the fluorosis areas on the border of Yunnan, Guizhou. The results showed that the clay samples had high fluoride content, acidity, and sulfate content. The research also found that the clay samples contained pyrite, which released hydrogen fluoride (HF) during heating. The possible reaction mechanism was the chemical reaction between acid and fluorine in the clay, producing HF. These findings provide new insights into the pathogenic mechanisms of coal-burning induced endemic fluorosis.

Summary: In order to evaluate the environmental risk associated with coal transport and burning, soil samples were collected in southern Italy. Analytical results showed that the majority of arsenic was found in the final residue of sequential extraction, mainly as occluded arsenic in rock formations. Speciation chemical analysis revealed that As(V) was the most abundant species present in the soil, with no organic arsenic species detected.

Summary: A temperature-modulated sensing strategy was proposed to identify and determine BTEX compounds. Highly effective identification of BTEX was achieved using linear discrimination and convolutional neural network analyses. Additionally, quantitative analysis of concentration was accomplished by establishing the relationship between concentration and response.

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 review investigated and analyzed the distribution, composition, and abundance of heavy metals and antibiotic resistance genes (ARGs) in landfill. The results showed that heavy metals have lasting effects on ARGs, and complexes of heavy metals and organic matter are common in landfill. This study provides a new basis to better understand the horizontal gene transfer (HGT) of ARGs in landfill.

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.

Summary: Based on the efficiency of catalytic ozonation techniques in enhancing sludge dewaterability, this study investigated its effectiveness in simultaneous reduction of antibiotics and antibiotic resistance genes. The results showed that catalytic ozonation conditioning changed the distribution of antibiotics and achieved high degradation rates. It also significantly reduced the abundance of ARGs, inhibited horizontal gene transfer, and decreased the signal transduction of typical ARGs host bacteria.
