We used logistic and restricted cubic spline regressions to assess individual associations and dose-response relationships between phthalate metabolites and gallstones, quantile g-computation and Bayesian kernel machine regression to assess mixed associations of phthalate metabolites with gallstones, and subgroup analyses to explore potential effect modifiers.

The global prevalence of dietary Se deficiency is a significant public health concern, largely attributed to the low levels of Se present in crops. The sufficient Se in plants and humans is determined by the presence of stable Se sources in the soil. The Leizhou Peninsula is an important agricultural region in China, but the concentration and spatial distribution of Se in its soils remain unclear. To address this issue, we analyzed Se concentration data from 3333 soil samples collected at the depth of 0-20 cm from the Leizhou Peninsula, covering an area of 13,225 km². The results indicate that the mean soil Se concentration was 0.50 mg kg^-1, with Se-enriched soils being widely distributed. This provides prospects for the development of Se-enriched crops. Using random forest (RF) modeling and correlation analysis, the clay minerals (Fe-Al oxides), chemical index of alteration (CIA), and soil organic carbon (SOC) have been identified as the principal determinants of Se distribution in soil. During the weathering processes of the basalts, Fe-Al oxides serve as a crucial factor in Se accumulation in the red soils. Furthermore, the tropical climate further contributes to increasing the degree of weathering and the proportion of clay minerals and SOC in the soil. Atmospheric deposition derived from marine and precipitation is another important factor that promotes Se flux into soils. In conclusion, the distribution pattern of Se is jointly determined by the weathering process of basalt and climatic conditions. The results of the geographically weighted regression (GWR) analysis revealed that SOC, Al₂O₃, TFe₂O₃ and CIA change spatially and exhibit a spatial non-stationarity relationship with Se.

Altogether 22 hydrothermal spring samples were collected from the six hydrothermal provinces in Southern Thailand in early November of 2023. Geochemical data represented by calcium chloride and sodium chloride type, most of which were influenced by seawater intrusion. In addition, the hydrothermal springs that located along local fault zones were mainly controlled by water‒rock interactions, indicating that hydrothermal spring quality was influenced by weathering. Hydrothermal springs located along the coastlines of the Gulf of Thailand and Andaman Sea were dominated by evaporation. Radon activity concentrations show value levels from 9 Bq/L (PG1) to 7,070 Bq/L (SR3), with an average of 580 Bq/L. Radon levels of hydrothermal spring attractions can be divided into three categories: (a) low radon levels below 100 Bq/L, (b) moderate to high radon levels between 100 and 580 Bq/L, and (c) very high radon levels greater than 580 Bq/L. The total annual effective doses for adults due to ingestion and dominantly inhalation of radon at hydrothermal spring attractions varied from 0.01 to 19.30 mSv/year.

Their long water change cycles lead to an obvious cumulative effect on pollutants. In this study, a targeted screening method for 74 PFAS in aquatic environment was established. The contamination characteristics of PFAS in surface water samples (0.5 m below the water surface) and bottom samples (0.5 m above the lake bottom) of plateau Lake Yangzonghai were studied and compared to a reference site in Dianchi Lake which has been severely affected by anthropogenic sources. Results showed that 32 PFAS were detected in Lake Yangzonghai with the total concentration (∑₃₂PFAS) ranging from 14.95 to 26.42 ng L^-1. Among the 27 PFAS with available standards for accurate quantification, 22 PFAS were detected, with the concentration of ∑₂₂PFAS ranging from 13.27 to 20.17 ng L^-1. Significant differences (p < 0.05) in PFAS concentrations were observed between surface water (22.12 ng L^-1) and bottom water (18.18 ng L^-1), demonstrating a stratification phenomenon. The spatial differences in PFAS concentrations in surface water were minimal, indicating that the surface water was uniformly mixed with limited local disturbance from human pollution. The main PFAS monomers were perfluorooctanoic acid (PFOA), 8-3 fluorotelomer carboxylic acid (8-3 FTCA), perfluoroheptanoic acid (PFHpA) and 2H-perfluoro-2-decenoic acid (8-2 FTUCA), while PFBA was not detected.

Employing EPA health risk assessment methods, the research delved into the implications of pollutant exposure on human health. Results unveiled average annual concentrations of PM_2.5, SO₂, NO₂, and CO, standing at 27.22 µg/m³, 72.48 µg/m³, 26.8 µg/m³, and 2.06 mg/m³, respectively. Intriguingly, PM_2.5 displayed positive correlations with temperature and wind speed, while exhibiting negative associations with relative humidity and precipitation. Conversely, both SO₂ and NO₂ concentrations showcased negative correlations with temperature, relative humidity, wind speed, and precipitation. Furthermore, CO demonstrated negative relationships with both wind speed and precipitation. The analysis of mean hazard quotients (HQ) for PM_2.5 and NO₂ indicated values exceeding 1 under 8- and 12-h exposure scenarios, pointing towards concerning health risks. Spatial distribution revealed elevated CO levels in the northwest, north, and east areas, while NO₂ concentrations were predominant in the north and south regions.
